While driving down the road recently my doors locked themselves and triggered the alarm. The car drove normally otherwise, but it was obviously very embarrassing...I felt like I was stealing my own car. I later tried locking the doors right after starting the car and all was well. Everything is still ok unless I forget to lock the doors manually. If I don't...alarm again. Could this simply be the door lock vacuum pump. If so, where is it located and how troublesome to replace? Thanks in advance...Bill

This thread locked itself too until moderator helped this afternoon. Please feel free to respond. Thanks...Bill

please...

Check the right front door locking mechanism carefully. If the over center spring which allows for locking and unlocking that door when the system is locked breaks, it allows the button to drop down slightly which is enough to start the automatic locking process.

Thanks for the reply. I've noticed that the lock cylinder is binding when I put the key in to lock/unlock. Do you think that if I replace the cylinder it will cure both problems? Thanks...Bill

I seriously doubt it. If you have the problem I suspect, it is in the latch mech in the door and not the tunbler.
