Several others have had this issue of the Drivers side door not unlocking via remomet or Pin pad. After careful diagnosis of the problem, it appears that a Part of the Latch mechanism has become sloppy, over years of use. There also appears to be a small actuator tha seems to be now inactive. WHen diagnosing the problem, I noticed that if you lifted the part the drop about 1/16 of an inch, the Lock worked correctly. Since I have not been able to find the actual manufacturing drawings of this mechanism, I arrived at my solution through trial & error. If you apply a small amount of tension on the Sloppy part, with a low tension extension spring, available at the local hardware store. Hook one end on the Link bar to the right side of the door latch mechanism, and the other end into the Hole in the Door Handle/opener. You will Have to adjust the tension, so it is not too much, otherwise the Lock plunger will never go down, if it's too much. This has been working now for a week, and it doesn't seem to be degrading. You may want to bend the Spring end into a loop, so it doesn't poke hole in your finger when you open your door, after successfully unlocking it with the remote. Now As to the pin pad unlock, most people don't seem to know that repeating the last digit of your pin code, unlocks the other locks in your car, just like pressing unlock twice does the same thing. Hope this helps, or at least leads to a clue on this repair,

Regards, Bobalew.
