Electrical problem
2004 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic

My doors won't lock when using the key fob. The horn will sound and lights flash as if they were locking and the alarm is set but the doors don't lock. All other functions from the fob are working such as trunk unlock alarm set and doors unlock.....any suggestions?

Thanx

Start simple, replace battery in key fob.

If you can lock/unlock doors using key in door, and buttons inside, then you will probably have to go to GM and have a dealer look at it.

Also check fuses.

Try finding the part GM said needed to be replaced at a junk yard. Only problem with this is that it will probably have to be flashed to your VIN, by GM.
