I cannot get my drivers door to lock. I tried using the key and everything it just won't lock. Any ideas? I believe this car had the vacuum thing in the truck replaced at some point. Haven't really driven this car to know any other symptoms. The remote arms the alarm but doesn't unlock the other doors either, although my main concern is to be able to lock up the car. Thanks for any ideas.

 

So are you saying none of your doors lock?
The door won't lock when you use the key manually either?
Are you sure the alarm is arming?
