This is a re-accuring issue with these cars. The first time it happened my car had about 98,000 miles on it. Now 13 months later the issue is happening again for a 3rd time. Yes, a 3rd time in 13 months. Each time we have this problem fixed it costs us about $500. GM is very aware there is an issue, and are not in the least bit supprised we are continuing to have an issue with teh Pass Lock Sensor. Our only hope is that GM will pay for the 3rd repair since we paid for the first two. I am not overly optomistic though. My first experience with Pontiac customer service was not pleasant. I was actually yelled at by the custom service representative, and had to ask him to stop yelling at me. We will see how it all works out.

NOTE TO GM: Don't let your customer service reps yell at the customers when there is a design flaw in your parts. This is not a tactic to keep customers purchasing your vehicles when you are in the middle of a major restructuring because other auto makers are taking your market share.

I also found that when i removed the rubber protector guard on the terminals, and cleaned the terminals thoroughly with a wire brush, replaced both bolts for the terminals, then let it sit 10 minutes with the ignition in the on position until the security light stops blinking and stays on for about 5 seconds, then it goes off, turn the car off all the way, let it sit for a minute or so, then try to start it, it worked fine. If it doesn't want to turn over the first time after all of this nonsense, let it sit for a minute again in off, and try again. We have had all of the same problems with ours as the previous comments, such as replace the fuel pump, fuel filter, no reading on the computer diagnostics, and so on. What a nightmare, hopefully this does the trick, and there are no more problems. Good luck to you all!

I have had this problem occur multiple times. It has been towed 4 times and taken to the Pontiac dealership 3 times. First thing they replaced was the ignition switch, didn't solve the problem. Another deal replaced another switch, didn't solve the problem. A third dealer replaced the command control module. Each time they assured me that it would solve the problem. $1200 later it still has the security light come on and it is a matter of time before it happens again. This is absolutely ridiculous. The car has to be towed every time because there is nothing you can do to crank it. I will never buy another Pontiac.

Without any major Pontiac manufacturers knowing the problem, My husband and I have dished out about $3,000 in repairs, car rentals and upgrading our AAA membership. We have repaired and replaced a fuel pump, 2 fuel filters, fuel pump relay switch and last but not least the ignition lock cylinder with the pass lock system reprogrammed. My car also has these issues when it is cold. My car only had a limited warranty so all of this money is straight out of pocket. Whenever the security lights pops on I drive it straight to a GM repair shop for them to do whatever it is they DON'T DO!!!

Yes, the great Passlock III All last winter I struggled with this problem, always waiting 10 minutes to start my car. I brought it to the dealership, (whom by the way had no clue how to reset it when it happen) they tested it, told me it was the ignition, and needed to be replaced for $250 installed... I asked them if they could just "bypass" the alarm system, or "deactivate" it, they told me no, it runs all through the car, and could not be bypassed. This was March of 2006. A few more times, and then by the end of April 2006, it stopped. All summer my car started fine, without any problems with the passlock III security system. UNTIL the end of November. For some reason whenever it begins to get cold outside, it acts up again... I WILL NEVER BUY ANOTHER GM WITH A FACTORY ALARM.
