I was on my way to a concert, concert traffic, on RT 1 going to Foxboro Stadium. We're dead stopped I give my buddy the keys to unlock the trunk, then when I try to turn on the car, it won't start. We pushed it a half mile and put in a parking lot. After sitting for a while it started.

This is the second time this happened. I had let the car sit, I work in the city and probably drive it once a month, sometimes more. I came back from a Doctors appointment, stopped to get a burrito, and the thing wouldn't start.
I towed it to a Chevy dealership. The threw me a $3,000 bill, and told me a Unicorn, excuse me a squirrel had chewed some computer wires and they weren't sure how long that would take to fix. The also told me they had to replace the passlock thing, $500 and a bunch of other crap. I don't drive it much so I haven't had them do any work.
Thank god for this site, if I didn't see all these other complaints I would have wasted three grand fixing a car that isn't worth the time. When I have a moment I'm going directly to a Honda/Toyota dealership and getting myself a new foreign ride.

Well I've been dealing with this for a year now. Most of the solutions have worked, aside from actually getting it repaired. But they are now no longer helpful. But since it is electrical...we all know the warranty on that from good ole' GM.
Now.... 9 out of 10 starts the lights strobe. It sounds as if there is a mad man in my glove box (actually coming from the passenger side fuse box) desperately performing morse code. When this happens..there is no A/C.. meaning it won't even come on. Then it will come on and just blow heat. I have to pull on my lights to stop the strobe effect, but the morse code still happens. I have driven with the sound alarm, radio locked, and seat belt lock light on. It seems to resolve in anywhere from 10 to 20 minutes.
I'm from the midwest..grew up in the General Motors town. Everything was GM. I will NEVER buy another American car...and Mr. Smith.. go figure.

I'm putting this in the 2002 Impala site, and also sent it to the 2005 site, since most seems to have been written about here and since I went to this 2002 description most to read about my problem. My vehicle is a 2005 Impala.
POSSIBLE SOLUTION. IT WORKS FOR US.
A Solution that Worked for Us. Pass Lock, Security Light Problem.
Here's a solution that worked for us and might for others who have had this problem.
Background: Bought a 2005 Impala in May. After about 100 miles of driving, the Security Light started coming on intermittently. Then one day my wife went to start the car and no start. I tried it and no start. I did the 10 minute wait and it started. I reported the problem on this site, but read other sites as well. I wrote to the individual who said he had a two minute fix on post #77 of 2002 complaints but he never responded. I had decided to have the lock cylinder and key replaced, but also decided to try all kinds of things first. And I found something that worked. I got into the car, put the key in, turned it to ON, but NOT to start. I let all the seat belt dinging sound stop as well as a slight electrical or mechanical sound in the column. No more sound. Then I turned the key to START. No more Security Light problem since for either of us. We have driven hundreds of miles just to see if something would happen. Stopped on the open road, drove 100 miles in one stretch, etc. THIS WORKS FOR US. So here it is in short:
1. Get in the car and shut the door.
2. Don't do anything except put the key in the lock and turn it to the ON position.
3. Let all the sounds do their thing and come to a stop. QUIET.
4. Turn the Key to START and start the engine.
It works for us and maybe it will for you.

Car would not start when turning key in ignition. Happened to us a couple times. Once at a self-serve gas station, wife got out of car to pump and had left the keys in the ignition. wouldn't start for about 10 minutes no matter what she did... it seemed to have tripped some security delay timer. We have noticed if you leave the keys in the ignition this tends to happen more. I have not had this re-occur for about 8 months by implementing the following habits (maybe I'm just lucky)
1. Never leave the keys in the ignition
2. Always turn the key completely off before pulling out (the key can be pulled out of the slot slightly before the off position)

Here is my story with a happy ending.
So I am aware of the passlock system but am looking for some more precise directions. Here is the story. Nieces car- She drives it home with no problems, gets in it the next morning and the key will not turn. I go and get a key and tumblers for it which also has the pass lock 3 wire sensor on it. I get that installed and it won't crank, security light flashing 3 times then battery light, back to security and so on. I let it set for ten minutes and the security light is no longer flashing but is steady, still alternating between security and battery light. Try to start it, still no crank and the security light goes back to blinking.So I read where this ten minute thing needs to be done 3 times, try that same result. Try the reset six times, try the E-brake set while doing it, door open, locked, unlocked, battery unhooked and rehooked after a minute, reaching through the window while on my knees and praying, etc. you get the point. Got the old key to turn in the old tumbler, put it back in and went through the resets and it does the same thing. Jump a screwdriver across the starter and it cranks fine. Next step is to haul the car to my house to work on it, just not sure what I am going to do once it is at my house.
So here is what I have done. I had hauled the car to my house to work on it rather than going to where it was at every night after work. I took the locking piece out from the old key and tumbler set that keeps the cylinder in place (normally the key must be in a certain position to release the cylinder) just in case the key locked up again and would not turn I could now pull the cylinder out at any time. I run the whole reset/reprogramming thing on the old key/cylinder. It works this time and when the key will turn, it starts and there are no security lights. I take the old key and cylinder out and put the new one in. The car starts but the security light is on steady. Stick the old one back in and it still starts with no security light. There are 3 wires (black, white and yellow) going to the passlock sensor, I cut the yellow and hook one end of my OHM meter to the yellow end coming from the cylinder and pierce the black wire with the other end for the OHM meter. At this point the car will still start but has the security light on and will not give me a constant reading so I put the car in reverse (won't start in reverse) and turn the key to the start position and hold it there. The meter slowly climbs to a steady .887K of resistance. I mention the slow climb because when the car was starting it would crank longer than I would expect before starting, in fact it cranked for about the same time it would take for the reading to settle. I do not know that much about resistors, normally if I need a resistor I just go to radio shack and find the one closest to my reading. The problem that I ran into is that they did not have anything that matched what I was looking for. So I buy an assortment of resistors for $12. There are literally hundreds in this bag. I plan on experimenting with resistors in series and twisting two together and such to get the correct resistance. I learn that by twisting two together you get roughly half the advertised resistance reading (some or many probably already know that but I did not). After testing numerous resistors with the meter I find one that reads 1.7??K, I twist two of those together and get a reading of .879K, close enough to the .887K a was looking for. So I strip some of the coating off of the black wire, not breaking it's connection to the cylinder. I hook one end of the resistors to the stripped section of black and the other end to the previously cut yellow wire (end going to the BCM this time, tape off end to cylinder). I solder these connections and tape everything. I did the reset of leaving the key on for ten minutes. Now with new key and cylinder it starts immediately and there are no security lights and I don't think there ever will be on this one anymore.
All of the searching that I had done shows that the passlock system is a known problem on these cars, leaving people stranded until the 1/2 hour key reprogramming is done. This could be something that could be done to avoid that problem in the future.
I have since performed this bypass on other vehicles with the same security system.
Anyone that wants more advice to do this or lives close enough and wants me to do this can contact me by E-mail. shofner_aron_w@yahoo.com
I will gladly perform this bypass for much less than what most have already paid the dealerships.

Just flat out embarrassing, really. I couldn't lend the car out to anyone, didn't want to risk stopping off at a convenience store on the way home from work for fear of it not wanting to start again. The occurance is completely random, and the remedy's are completely random. It's not a matter of doing things in a certain succession or waiting a certain amount of time. Problem is a loose connection at the terminal of the Body Control Module (BCM). Either simply needs to be cleaned or the BCM and opposing terminals needs to be replaced. Replacing relays, starter, ignition switches, etcetera won't solve the problem; it'll just waste your money.
Tell your mechanic to find GM Technical Service Bulletin #040847003 for instructions on how to fix this problem. FYI: GM will charge 200-500 bucks to fix this.

All I have to say is I am glad I am adding to this escapade. I drove my car literally out of the showroom and away I went!!! I absolutely LOVE this car and I have never had ANY problems with this car until now. Its roomy, great handling, sporty and great on gas for its size.
Lets reiterate now what everyone has said and my past experience, Check Engine light on one day off the next? No response from the ignition when you turn the key? Security Light Blinks or on one time then off the next? Dash lights blink on and off and then after the key sits in ignition for a minute all the dummy lights come on sometimes they blink Check Engine Soon, Service Traction System, Battery, Low Fuel, BUT, I have found that if all the lights come on the dash and the radio does NOT come on there really is no power to the car, as soon as that Radio comes back on you are in action!!! Or When you put the key in the ACC position you are getting a ticking noise from the passenger side fuse panel, I pulled those relays out and it didn't do anything, when car decided to start it started without the Battery Relay so no worries there its not the relay. I have taken the key out and back in several times no response from ignition. I have taken the key out of the ignition and the car would still be chiming like the key was in the ignition : ) I too have taken the battery out, unplugged computers, and the problem is intermittent!
This started happening about two weeks ago and its getting more frequent. From reading I heard there may have been hope to bypass the passlock. If you know of anyone who has had this done, PLEASE email me. I don't want to get rid of this car ITS PAID OFF FINALLY! Still love GM but not if they can't address the #1 thing wrong in the Impala category!!! Makes me look at that Foreign Competitor closer since they have almost forever warranty and I have never heard of anyone having problems that couldn't be fixed! Get off your A** GM and fix this! Count me in for a class action!

Finding this site through searches on the internet I am surprised by how many people have the same problem I did as far as the intermittent crank and waiting for 10 mins because of the passlock system failure. I want to thank all of the people for the valuable information. From all the reading I've done it looks like even the newer Impala's are having the same problem. Its a shame that Chevy is dancing around this issue and cannot fix this. I see alot of people spending alot of money and there problem is not fixed. Clearly this is a recall problem that even a blind man can see. However dealing with the same frustration that all of you had to endure I believe I have come up with a fix that worked for me. Ever since I did this fix I have not had the security light come on at all and my car has started fine now. I have not had the intermittent crank or the having to wait 10 mins to start the car. Also this fix is very easy and takes about 2 mins to do. The thing I find amazing is the fact that I am not GM certified and I fixed the problem that they should know. Now first of all Im not going to say that this fix is going to work 100% for everybody. It worked for me.

My 2002 impala never wants to start because of the passive lock system. I have been stranded lots, and I do mean lots of times. At first letting it sit for 10 to 15 min worked but now 2 years later its all night. I have disconnected the battery, I have put the key on ACC with my foot on the brake taken it out of park and slammed it back into park and the started it. That only works sometimes. What should I do?

Ok so I'm another added to this list of owners whose Impala's have this stupid passlock problem. In short the security light comes on and I can't turn over the engine. Waiting 20 minutes and cycling the ignition a few times starts the car but its getting more frequent.
I visited the dealership a few days ago and they said "the sensor needs to be replaced". So yeah about 300 bucks...but wait there's more to this tale.
Months back there was only one issue with this car...it didn't like to start on the first try. Never though anything of it...just tried again and away I went. After doing some research I've found people who have had starter issues that have caused this passlock issue to arise. Apparently the wiring is bad with the starters...which I would agree as the starter works...just not the way it should. Anyway I'm going to look into the issue further...I refuse to pay hundreds of dollars for an electrical problem...thats ridiculous. I agree that there should be a recall for these issues as there's definitely enough of them.

My car would start only when it wanted to....sometimes without a glitch, then out of nowhere, I was stranded! There was no pattern, just random!! I tried everything my manual told me to try, including some extra stuff (holding my breath, finger in ear, foot on the ground-other one sticking out the window) you get the idea...nothing worked! Finally, I took it to someone who knew what they were doing (at the dealership), after taking it to someone who did not know what they were doing, and after he replaced the ignition and gave me the new keys(that was the most expensive part $95) I was home free!! Never happened again!! The other work did not cost but $50..I had a warranty!

I took my car to Goodyear only to have my radio fuse unplugged and I was told that I have to take it to the dealership because they were the only ones who can fix it. Goodyear kept saying that I need to get another control module. This is crazy, Chevy needs to consider this a recall because this is too many complaints of the same problem!!

What is up with the security light on this car? I have had the passlock sensor replaced 2 times already once under and extended warranty and the second time out of pocket, now 5 moths later after I had it fixed its broke down again due to the passlock sensor, sad part is my mechanic is going back and forth with Chevy to get the part replaced under warranty because its only been 5 months and Chevy wont do anything about it considering this is the 3rd repair in less then 3 years, If so many Chevy owners are having this problem why hasn't a class action suite been filed against Chevy, I mean come on its 400-600.00 a pop everytime it has to be replaced and its just not fair!!!!!

I purchased my Impala new and never had any issues until about 2005. We were driving home from a trip and the check engine light came on and stayed on for about 400 miles. We had to have it reset by the local auto store even though there were no error codes.
Then about a year later I drove about 10 miles to the bank, got out, went in, came back out within 5 minutes and my car would not start. I never noticed any lights coming on such as the security light. I called my husband and by the time he got there, it started. It has only done it 4 times since, usually at inconvenient times or locations such as at the gas station, at work at night on a very cold winter night, and twice in the garage when I needed to run errands.
I just noticed last year that the security light would come on and then go off. Sometimes it would stay on for a long time. I also noticed my Onstar lights started acting weird. One day the light on the right would be green, the next day it would be red. I would call Onstar to have them run a diagnostic check and they would always tell me that I had a bad connection in my Onstar antenna. I never had that checked out since I didn't plan to keep the Onstar much longer.
We have never spent any money to try to fix it. The dealer says they have never heard of it so why bother giving them money for nothing. They did say that it could be the chip in the key. I have tried both keys and that didn't seem to help.
We have found that if we wait 10 minutes, it usually starts right up. However, the most recent time (which happened to be on that cold winter night) I tried to start it when leaving work and it didn't start. I let it sit for 10 minutes and it didn't start. Then my husband suggested I take the key out and wait 10 more minutes. It didn't start that time either so he suggested that I put it in neutral and it started right up without waiting another 10 minutes. It has not happened since! We dropped our Onstar subscription in December. I wonder if that is somehow related? Or it could be that it is about to happen any day now.
We just purchased a new car in November. Guess what? It is not GM!! We purchased our first foreign car--a Nissan! There was no way we could bring ourselves to purchase another GM and we had decided a long time ago that we were finished with Ford after owning several with all kinds of problems.

I've been putting up with this for almost a year. The initial time it happened, I was stumped. Came in the house, got online and did a search for "starting issues with 2002 Chevy impalas". This site was a top hit, I checked it out and was very surprised at how many other people are putting up with this.
At time it does not start. I have to do the emergency brake routine. Sometimes the security light stays on sometimes not. Service engine light is on, sometimes not. Sometimes the security light stays on for the duration, sometimes not. Today I noticed that my security light is on and there is a "tick" noise coming from the passenger fuse box. Head lights blink in sync with the tick noise. Tick noise stops when I pull on my headlights. Now the A/C system likes to tick when I use it when the security light is on. If the security light is off, the the A/C works just fine.
I come from a GM family. Many relatives and friends have worked, still work or have retired from GM. I did my part to support the auto industry since is was falling so far behind in the competition by purchasing this car brand new. Sad to say, my next car will not be American. Sorry GM...the quality of the foreign cars is superior to our lack luster domestic models.

The problem was due to the Internal failure in passlock sensor...which was replaced....well low and behold it happened again! The dealership wants to charge me $400 to fix the problem. I called 800-222-1020 and was told by the person answering the phone that I could have an email address to voice my complaint!!! He suggested that I take down an address and write a letter, which I plan on doing!! The dealership tried to tell me that this happens more frequently than not and blamed the problem on a key issue since the system had to be reprogrammed all at my expense of in excess of $400.00....UNACCEPTABLE....for the price I paid for the vehicle!!!

I've had the same problem as everyone else here. I went to start the car and nothing, even though the lights and dash and everything seemed bright. It first started about 6 months ago where the same thing happened. I took it to an electrical repair shop at that time and they couldn't find anything wrong at all, so I just left it. About 3 months ago the check engine light came on and stayed on for 2 or 3 days and never came back on again. In the last few weeks the security light would stay on continuously sometimes when I'd use the car, but not every time. Tonight was the second time it failed to start.
I bought the car new and I really like it and the way it handles and everything but I've been thinking of trading it in because I don't have too much confidence in its long term reliability. This problem now is really gonna speed up the process of trading it in and I can tell you, it certainly won't be another Chev.
Has anyone heard of a good cheap way of bypassing the passlock sensor or any word on GM doing a recall for this obviously common problem?

Had body control module replaced by GM dealer, $470, - no help. They said then would try (?) replacing ignition and Passlock module - $700 - 900 estimate! GM customer service no help, so I'm not even trying to deal with them anymore. I like the car for several reasons; size, driveability, relative comfort, and especially gasoline economy. BUT, this problem trumps them all. I am very interested in potential by-pass surgery which two or three have expressed on this site. Someone please give me the details someone.
Have also had steering gear problems twice and major problem with intake manifold gaskets leaking coolant. Over $1000 for repairs of these.

This gets to be so annoying. You go out to start your car and nothing happens. We put a new starter on b/c this is what the auto parts store said and that didn't work, now they telll us it needs an ignition control modulator----why pay all this money, evidently it is an ongoing issue with ALL of the impalas that GMC needs to fix.

Exact same problem as everyone else. Security light on, sometimes interior lights will stay on while driving, keyless entry doesn't work, power locks and truck wont work, occasionally car will not start, etc. The car not starting has happened several times. Usually I can unplug the positive battery cable and then wait a few min. and it will start. Other times I will have to wait several min., leave the driver side door open and it will start. Good news is that the car will start....eventually. Bad news is that NO ONE knows how to fix it. I am looking for information on how to bypass the passlock system. I have heard this will fix the problem. I have an after market Pioneer stereo with an iPod adapter installed so my OnStar is already disabled. Anyone with information can email me at jenniepace@hotmail.com. THANK YOU!!!!

Same problem as all the rest. Now I don't feel so bad. A family member just bought
this car for me. It's pretty, drove well from the lot. After reading all the post (every
one) I feel chumped. I'm trying to figure out - how I can give it back since it's
a couple weeks old. Maybe the dealer will take it back. That's what GM is afraid.
I noticed a problem with the key and ignition and/or icylinder. I had know ideal it was on this level of complaint. And like the rest of the post here, I'm having the same problems w/ the flashing of the security lights - additionally, I it also rest the time as if
you unpluged the battery. Starting to show starting issues. For now, the option seems to be, put the key in, let the system recognize the key (for a few seconds), while the door is open, and start the car. I'm not sure how long that will last - but I getting pretty damn tired of it already. I noticed problems when closed the door and try to start
immediately.
Additionally, I have already given notice to family not to drive it. That hurt, especially when you have a teen looking pretty hard at driving something. Oh well, this won't be
that car.
No one likes the media, and GM already has problems. But if you won't this problem
to get any notice - then the media is your only option w/ class action lawsuit of course. "60 Minutes" perhaps, maybe on a couple morning shows. The Net is a
great information source, but you need the media to get the correct attention it
deserve. Additionally, someone will need to have dangerous, adverse consequences
happen before it becomes a class action lawsuit. Until then GM can pretend it doesn't
exist until the cows come home.
This is an automatic recall; but GM has told you what you can do w/ it. Deal with
it, or get rid of it. But we're not going to recall it.
It reminds me of the problem with "FORD" design problem with the "ignition
control module" mounted on the distributor on all models from 88-92. The module
would cook/burn-up after lengthy travel and you would come to a stop. It sound like
a fuel pump problem, and/or flooding problem but it wasn't. It was a 29.95 module.

My problem is not unlike everyone else's who owns an impala or malibu. Its the worst car i have ever owned. My car used to do the problem where all the lights would flash in
information box, like the battery, the security, everything accompanied by the radio
locking and the AC blowing hot. I seem to have gotten that problem fixed, my
electrical mechanic said he found a wire backed out of the computer and touching
the back of the computer causing it to short out. Although I am still having the passlock
problem. The same symptoms happen, the security light will flash, and within a few days
the car wont start. I have replaced the ignition, ignition switch, body control module, and
the wiring harness to the bcm. Nothing works, every time I leave the mechanic they
say, thats going to fix it, and I always return within 3 days. The next thing i am going
to try to bypass the passlock sensor, I just don't know how. If anyone has done this
and can explain how, please let me know. I told my mechanic that this can be done
and he said find out how and he will do it. I will never own another GM product again
in my life, I dont care how long their new warranty goes, its not worth it because they
wont stand behind their product.

Problem started happening more and more. Finally got ignition replaced. Two weeks later, another computer went down. Contacted GM for help, guidance, advice. Never received an answer. After two costly repairs and no communication from GM, I came up with a great solution. Final solution was to get rid of GM car and buy a Toyota. My mechanic said this problem is only found in Impalas and Malibus. Should be a recall, but buying American, GM would never admit it.

As much as I would like to gripe, rant and yell at Chevrolet and GM, I'd rather help you guys with my advice. The passlock problem arises from the fact that the ignition system does not recognize your key by the time you first turn the ignition switch after inserting the key into it. You have probably noticed that after inserting the key, with the door open you hear the "ding, ding, ding, ding,..." sound, alerting you that door is open. This may often come as a very faint "ding, ding, ding,...." increasing in volume as seconds go by. At times, there is NO "ding, ding, ding..." DO NOT TURN THE KEY. This is a sure sign the car will not start if you turn the key. Instead, remove the key, and re-insert it until you hear the loud ding, ding, ding, ding, (annoying as it is) with the door open. I have made it a habit to insert, remove, insert, remove, insert, before turning the key.
Rule here is to give the system time to recognize your key; if you are in a hurry, follow this procedure, so you don't miss the important meeting, date or pick-up.
And, yes...next time...shy away from Chevrolet!!!

Same as many of you who wrote in here my 2002 /3.8L Impala has been giving me problems since 2004. Spending money at many mechanic shops including the dealership gave no result until today. Every time something is done about it like changing the battery, replacing the ignition switch, wait the 10 min or the 30 min or keep the driver door open worked for short period of time, but never solved the problem permanently.
GM wouldn't admit there terrible engineering, everybody should call GM and let them know about this problem and ask them to start a recall as soon as possible. If anybody was able to find a solution for this problem please let me know. Thank you in advance.

This car was not really giving me problems just a few minor things. It is well taken care of; however, this problem has been annoying me for quite some time now. My car always starts out on the second or third try. Starting is a difficult process for a car and it wears out the parts the most.

HOW DO YOU REPROGRAM SECURITY SYSTEM? What is causing these problems. Security system seems to prevent car from starting. Stranded again. Car towed home again. Security and other lights come on, radio does not, Disp. hold in time will come on and then go out, items do not come on to scroll. Previously, removed fuse for door locks (use door locks manually) trunk lock hasn't worked in months. IT APPEARS TO BE THE COMPUTER SYSTEM-PASSWORD-SECURITY SYSTEM. I Called in a complaint to NHTSA (NATIONAL ___TRAFFIC & SAFETY). They have live people to take complaint over the phones for investigation to possibly recall. call 888 327 4236.

Same problems as most of the others. Radio won't work and displays LOCKED, anti-theft red LED remains lit, SECURITY warning in message center, and airbag/seatbelt icon stays on. Day running lamps will not come on and occasionally power lock switches will not function. My car will usually at least start in this mode, but then fail the next time. All problems have been during start up; thankfully it's never died on me while running. All other driving functions and gauges work properly even in this lockout mode.
Replaced ignition cylinder and housing (which contains the PassLock sensor), but the problem persists. The 3 cycle (30-minute) reprogramming procedure has worked for me every time (5 times over 2 months) - allowing the car to start, even if it doesn't always clear the error (warning lights and such). BCM connections look OK. I plan on trying a new ignition switch and if that doesn't work will bypass the PassLock system as others have suggested.
Since it's not explained in great detail, I thought I'd write out the reprogramming procedure. This is actually to program a PassLock sensor to accept a new key, but can be used to "reprogram" it to your existing key:
1) Turn key to START and leave it in the ON position. Car will not start, and the SECURITY warning will display in the message center.
2) After 10 minutes, the SECURITY warning will disappear. Turn the key to OFF and wait approximately 10 seconds.
3) Repeat steps 1 and 2 a total of three times.
4) The car should start on your fourth attempt.

Security light went on for no reason but then went out. Within 2 weeks car wouldn't start. Had it towed 3 times. Replaced battery ($200), cleaned keys with eraser, threw a key out. Replaced computer system ($800.). Still have problem. Try not to change keys. Security light going on is an indicator it will happen. When it does, let car sit for 15-20 minutes with key in ignition.

Anyone with the passlock problem can be fixed for about $5 and a little bit of time and know how. Bypass the passlock sensor and you will have no more trouble with it. I bypassed mine, and have no problem since. If you would like info, send me a message and I will help you fix if you are interested.

Same problem as everyone else. The problem has gotten worse though. Before, I could just wait in the car for about 10 minutes and it would start, but now it will not start and my battery will get drained down if I don't disconnect the battery. I have seen the head lights would not turn off, the dome light would not shut off. The radio would not work, the locks would click, the truck unlatched all by itself. Right now the car is parked and not being used. If I need to drive it, I connect the battery cable, do my running without shutting the car off, get it back home and disconnect the battery.

I have had nothing but problems with my 2002 Impala. I go out to start the car and it won't start. It's really embarrassing especially when you are at a gas pump and can't move for 10 minutes. I have figured out that if you get out of the vehicle do not open the doors again for 10 minutes or it won't reset. If you are in the vehicle you need to sit for 10 minutes and wait. I cannot afford to have the problem fixed by the looks of the cost. I am a single mom and rely on my vehicle a lot. I am glad to see that I am not the only one with this pain in the ass problem. Obviously Chevy needs to upgrade their parts????? I would love to get into the lawsuit if anyone has any info about it.

This car ran with no problems up until two months ago when it started showing the Security light and randomly refusing to turn over. When we took it to the dealer they recommended replacing the BCM and ignition switch for a whopping $1000. Hell no. After reading up on the problem we found a report by GM which describes the following:
"Security Light On, Engine Will Not Crank, Diagnostic Trouble Codes B2958 and/or B2960 (Repair Poor Terminal Connections at Body Control Module - Models: 2000-2005 Chevrolet Impala, Monte Carlo
Condition
Some customers may comment on an engine that will not crank. Others may comment on the security light being on.
Technicians may find DTCs (diagnostic trouble codes) B2958 and/or B2960.
Cause:
These conditions may have several different causes. In each case, however, testing of the BCMs (BodyControl Modules) replaced for these conditions are frequently found to be operating to specifications and are believed to have been replaced needlessly. A change was made to the BCM hardware in February of 2003. An
updated BCM can be identified by a GMAN169 or higher number found on the BCM part label. This hardware change was made to prevent the remote possibility that a BCM, built after the GMAN169 number,
could be the cause of these conditions.
Correction:
The following are the likely causes of these conditions:
1. Damaged or loose/unseated terminals in these BCM connectors may cause a security light or no start condition:
^ BCM connector C1 (24-way, pink in color), terminal B9 (white wire, circuit 1459)
^ BCM connector C1 (24-way, pink in color), terminal B12 (black wire, circuit 1835)
^ BCM connector C2 (24-way, grey in color), terminal A3 (yellow wire, circuit 1836)
So, this is a known GM issue and your dealer should read this report as well so that they do not overcharge you.

I'm having the same problem as everyone else. My car sometimes starts ... sometimes doesn't. I've tried all the recommendations about leaving the key in the ignition for a certain amt of time. Sometimes it works ... somtimes it doesn't. There have been times my husband and I did get my car to start but the lights keep flashing but radio doesn't turn on. I also don't think my air conditioning works at that moment either. I also have a problem with my turn signals not working all the time. I know that's a separtate complaint but I thought I've voice my opinion now. My automatic door locks aren't working either. Car was great up until this and I'm furious to hear that Chevy won't stand behind the problem and do the recall. I'm not going to spend $700.00 to try and get my car fixed if Chevy won't guarantee that will fix it. THEY MUST DO A RECALL!!!!

Whew.... I am so glad I am not the only one who has encountered this problem. One day out of the blue in mid August, the '02 Impala just died.
The warning signs were there but I did not know they were warning signs..... almost inaudible clicking noises from the dash, the "Security" warning light briefly making its presence know in quick flashes upon starting and the keyless fob working intermittently (sp?).
At the end of the work day in Phoenix (still 110+ degrees), the car would not start. Jumping did not help. I called my brother, took the battery out and I took it back to where I bought it from since it was still under warranty. I reinstalled the battery and the car started fine.
The next day, the car died again in traffic after the A/C was turned on. Took the battery out again and the store was very understanding in giving me a second battery in two days. This got me thinking, "Could it be the alternator?"
I replaced the alternator ($167.00 plus $30.00 for friend's labor and $20.00 for belt tool) and the car ran fine for about four days. However, during that time, the same warning signs started appearing again. On the fourth day..... dead again.
The power source worked for a few minutes allowing me enough time to close the windows. Like others, the key just turned in the ignition. I called a tow truck ($77.00) to a local shop. The diagnosis ($90.00) indicated an electrical problem beyond their capabilities and involved manufacturer recoding. However, they were able to get the car started again.
I said "Thank you." and drove to Bill Heard Chevrolet on McDowell Road and Scottsdale Road in Scottsdale, Arizona. They could use the auto shop's printout but it might not solve the problem.
I returned the next day and paid for a dealer diagnostic ($95.00) and went to work. They called a few hours later and indicated an ignition switch failure. They were 80% certain this would solve the problem. I paid for a new ignition switch ($402.00) and left.
The car worked fine for another few days before dying again on a Saturday after 4:00 pm. Now the power door locks stopped working as well. After praying to a higher authority and turning the key in the ignition for about 10 minutes, the car started again.
I took the car back to Bill Heard Chevrolet on Monday morning and they did another diagnostic for free while I was at work. They called a few hours later and told me I needed to replace the body control module. With no choice but to pay (another $430.00), I had it replaced.
Thus far, no problems starting the car. However, the "Security" light has been making sporadic appearances again. I have 7 more payments to go, but I am done with General Motors (and Chrysler... my '97 Intrepid was a nightmare from hell).
This seems to be a very common problem for this particular vehicle and General Motors seems to know about it.
I am waiting for a recall so I can get my money back and use it towards a down payment on my Camry or Accord. Take that General Motors and Chrysler!!!!!!
I am sorry I rambled on and on, but "Thank You" for letting me rant. I wish this will help someone else and spare them the accompanying headaches and hits to the wallet.

First problem I came across was when I removed the key out of the ignition, the front/back parking lights would continue to blink rapidly. Next, all dashboard lights did the same while making a loud ticking noise. To top that off, the battery was continually being drained. Every night I had to undo the battery and every morning had to reconnect. I live in Florida and connecting and disconnecting a battery in 90 degree weather is not fun! Finally, took to Chevy dealership, they said it was the bcm. Had this replaced for 480.00. THE NEXT WEEK, my speedometer stops working. I call Chevy, they tell me this has no direct connection with the bcm and it would cost me another $50.00 to tell me what's wrong. AND, if I have the speedometer cluster replaced it would cost OVER $500!!!! Now, the dang thing will not start at the most random times and the security light comes on and off. I loved my Impala but now I will look for something else other than a Chevy.

Happened once or twice, beginning at 25,000 miles. I'm now at 60k and see the security light flash as I drive every now and then, but thankfully I haven't been stuck in a bad place so far.
The Passlock sensors are known to be a problem and having heavy key chains (e. g. tons of keys, bottle openers, etc.) supposedly is a contributing factor in them going bad.

GM said they had never heard of such a thing as the ignition locking out for 10 minutes and then miraculously starting. My stereo installer, when hearing of my troubles asked if it was a malibu or impala, 2002 or 2003. I have a 2002 Impala. He said no problem. For $100.00 and 1 hour, he installed an inline resistor that matched the resistance the pass lock system looks for when the key is inserted in the ignition.

This car is a POS. I went through this for months. I am a single mother and CANNOT afford what it cost to repair this vehicle. The ignition switch was changed out for a new one. GUESS WHAT? It DID NOT fix the problem. That was at a cost of $310.00 and no car for 4 days. Does GM have any idea how difficult it is for working class folks with kids to go without a vehicle???
I went into the store two weeks ago, one of the hottest days in Indiana -thus far, (a necessity) and the car WOULD NOT START. I had to sit there for over an hour. I will swear on my life, I had a heat stroke that day. GM WOULD SAY - well why didn't you go back into the store or call someone for help. WELL GUESS WHAT GM, IT'S JUST ME OUT HERE! I went home, vomited, had a fever and chills due to having to sit in that vehicle waiting on the damned thing to go through it's 3-cyle-every 10 minutes-BS. And it took - 6 CYCLES - NOT 3 = 1 HOUR!
Finally, I got desperate and had to take the car to the dealer and OF COURSE they changed the BCM. ANOTHER $370.00.
From what I am reading, even after that part is replaced it can and most likely will fail again.
I am going to trade this car off as soon as I can and I WILL NOT be looking at another GM PRODUCT!~

When my car and myself arrived at dealership I got told by same guy that they might have car up to a week before they can even look at it. I have two kids, two jobs, and one car. You do the math. I was pissed. (although it was great reason to explain to wife that we needed to rent an 07 Silverado 4x4 crew cab - what a bad*** truck!) Was reunited with Impala wednesday (5 days in shop).

Engine locked due to security code feature. Tried to work through GM dealer and GM 800 number with no luck. They had no records of other problems by other GM owner, yet my father just bought an 06 impala (company car) with the problem occuring in the first 3 months. Triied just about everything. Lock/unlock 3 times, let sit for 10 minutes, disconnect battery. Sometimes these tricks worked, other times they did not. I finally had a GM dealer erase all codes in the system. They said it had more than 20 error codes, ones that did not make sense like dome light out when the light worked fine. GM needs to get their act together. Could have been stranded somewhere in a bad neighborhood with a defective automobile.... Would make a big PR crisis for GM.

My 2002 Impala LS first encounter with the electronics was a hard shifting transmission that would clear by pulling over and restarting. That problem seemed to clear up on it's own but then I started blowing fuses for the electric door locks. Next the security light started coming on but was only annoying and cleared when restarted. This progessively got worse (about the same time it was getting hotter outside) and would turn the security light on, cause a relay switch to click (right side dash) and make the daytime running lights turn on and off as well as the A/C compressor. Occassionally this will worsen to the point of the battery message coming on and when the ignition is turned off the headlights and tailights stay on until the battery is disconnected. Another intermittent problem is that the car will not start at all and the "locked" message comes on the radio which indicates the passlock system didn't want to be left out of the fun. Of course letting it sit and think about it for 15 minutes allows me to start and go. I'm going for a new BCM but from what I've read here and several other boards, this may or may not solve the problem. I suppose I should also have the ignition tumbler checked as well as have a new key made (bad chip in the key). Those seem to be the most common attempted fixes the dealers do although I'm not convinced there isn't another underlying problem... a ground or short possibly?

The car would not crank. Not even click. There seemed to be plenty of juice in the battery, but put it on a charger for 45 minutes anyway. Tried to start it after that, but nothing changed. Got the car into neutral, and then it started. Seems OK today. About a week before, the SECURITY light came on for no reason and eventually went out. It has not reoccurred. Is there a link? Not sure and I suspect that the Chevy dealer will not know either. At 50-60 bucks per hour, I do not feel comfortable letting them dork around with my wife's car since if there is no "code", they will not know what the problem is. If anyone has a similar problem, please let me know if you can get the car to start in NEUTRAL. Did mechanics seem to KNOW MORE prior to the use of onboard computers in cars? Or does it just seem that way?

Dealer had 3 days and said can't find anything because it started fine when they tried.

Just like the others a real pain in the AXX. Really inconvenient if you have to go somewhere and the car won't start. Happened several times. First couple of times would call Triple A. By the time they got here the car would start. Felt like a real jerk.... Dealer wants a $100.00 just to look at the car. How can they diagnose when problem is so sporadic. One dealer told us not to use the remote entry which worked for awhile. Now we just use the key and it started happening again. Message center is all messed up. Get different messages all the time.............. Chevy is no help.....................

I join the other two people as far as the car not starting. Very weird.... runs great and then all of a sudden it won't crank over. I have not had the battery changed nor have I went as far as to take it into the dealership. I did however, call GM with my problem and they informed me that it could be numerous things and I should take it to my local dealership. GM had no prior complaints to this problem. This is very frustrating and I as well as the others have to wait 30 minutes and then it starts just fine. Also, may I add everything else works--it just doesn't want to start sometimes?? If anyone has a solution please advise.

This is a really annoying problem, just when I have five minutes to get to work and be on time, the damn car won't start, due to the security lock out, I have to wait 15 to 20 minutes to start my car. GM really needs to recall this piece of crap.

First time it happen was under warranty in Little Rock, Ar Dealer gave us a story of cut wires and we beleived the story. It has happen many times since and the solution that works everytime so far -set parking brake turn ignition key on for 3 minutes then off, do this a total of 3 times on the last time watch the flashing security light - when it stops flashing you can turn off your ignition and bach on and it starts. Was told by a mechanic at a dealer who denied GM had a problem. Showed him all the problems found on the internet and he admitted GM had a problem and stated to apply the parking brake and with a stopwatch time turning your ignition on/off 3 times for 10.5 minutes. This reset the security system.

Security Light on the dash board comes and goes but this means the car will not start for at least 20 minutes. I called local service however they indicated that this is a dealer issue. The GM dealer with inconvenient hours, charged me $100 to say their tests show error codes. For $300 I could purchase a part that might work if not, pay an additional $500 for another part that SHOULD fix the problem. The dealer's hands were shaking nervous with the $800 figures on paper. I walked away from this shocking experience. The dealers know this is a recall issue yet they will not admit it or help in any way except to take customers money and await their sale of the vehicle. I have yet to come up with a solution to the problem. If anyone finds one, please let me know, the winter cold makes waiting 20 minutes for the car to start more than sad. I will never ever buy another Chevy!

Car starts sometimes. I have to leave for at least 2 hours. Then car stopped starting altogether . Took battery out of car had tested and was good and was replaced. Car worked fine for two weeks then same problem the dreaded security light came back on. Got where I was going came back out car would not start car would not jump off took knew battery out took back to advance auto said battery now bad put another battery in cranked first time worked for one week then security light came back on then next day went off live with not knowing if car will start when i get in it. Can't see paying for car and called gm. They called me back said they have had no complaints. HAVE FREIND THAT WORKS at a chevy dealer and says mechanics say they have a lot of problems with passlock system and say that the part is about 300.00 plus labor, but do not know if this will fix problem. If anybody finds an answer let us impala owners know . SHOULD HAVE STAYED WITH FORDS.

The security system constantly activates and locks the fuel injectors so the car won't start. Took it to the dealer and they were going to charge me over 100.00 just to look at the problem. This has become a huge issue since we have two newborn children and live in the wintery midwest. At times it takes up to 30 minutes to have the security light stop flashing and then I can start the car. As I have read above there has been little if any sympathy from Chevy!

I bought the car new and as soon as the GM loan was paid off the security light would come on about 10 minutes into driving. The light will be on and change to battery light, then change to service engine soon. I have had 2 times of not starting. First time I waited 30 minutes and it started just fine. 2nd time I opened the door and it started. One time of the battery going dead. trunk wil not open when car is in park. Door chime will continue for 30 seconds after closing door.
Took car to dealer and was unable to verify the problem, no codes were set. told the dealer the headlights would go out if you used the dimmer while driving.. Dealer did find the multifunction switch was bad and replaced it. Was told that should correct the problem. 10 minutes down the road, same problems.
Cost: $ 200.00 for diagnostics
550.00 for multifunction switch
I will think long and hard before buying another chevy

From reading the reports, it appears this is a common problem with this car. Since this security comes as standard equipment, GM should pick up the repair tab or disclose a procedure to disable it.

This is my second posting about this piece of crap. I had the body control module replaced and it's been fine (for this problem only, as there are many other unrelated problems) for a few months. Driving into work this morning, 11/8/06, the freaking Security light came on AGAIN! I have been having so many problems with this car I am about giving up hope. If anyone has any clue as to why this keeps happening, I would really appreciate an email (use the Send Comment link below). Thanks!

all of a sudden car wont turn over at all. turn ignition, nothing happens, no sound. battery checks out ok. security light has come on prior. never know when it will happen!! will start later but very much a problem as it can leave you stranded.
can lock and unlock car twice from inside and turn key on and wait at least ten minutes then turn key off and on again and will start. this should be a recall item from Chevrolet! costs $400. to fix and could happen again then!! has anyone had it fixed? if so, what happens then?

Car wouldn't start. We disconnected the fuse for the security system. Lights inside and out flashing continually, security light on constantly. Took it in to the dealership where purchased. Told it was the "Receiver" ($189CDN) that needed replacing. Picked it up, same problem. Did some net surfing to find others with same problem. Suggested BCM solution to mechanic. They weren't sure and didn't want us out anymore money - right! Still waiting to hear what they can do after paying $400 dollars for absolutely squat.

2002 impala starting problems because of passlock - Wife, kids and myself have now been stranded in the past 3 weeks because of this problem. 3 months ago mechanic replaced the ignition - worked ok up till 3 wks ago. This is a problem affecting all Chevy models and has been going on for years. Chevy refuses to do a recall. I will get what I can on a trade in and never buy a Chevy again.
