Thread: New to this Form and my fob won't lock my car :(

Passenger side lock intermittent?

Windows or side mirrors movement intermittent too?

Alright, now we're getting somewhere.

All power locks are sometimes inoperative on all doors.

This may indicate that the lock control circuit is shorted to ground. Although, I guess a power short would do it, too.

Short to BCM (under panel under steering column) is possible.

I have similar problems with locking my car, a 2008 Grand Prix: the previous problems with the key fob were solved in general by purchasing a keypad from keylessfix.com. HOWEVER, not only do I have trouble LOCKING the car with the remote, I also often cannot lock the car using the switches on the doors, themselves. I actually have to go around to each door and manually lock them. I can easily UNLOCK my doors using the remotes or the door switches, and I can hear the car make clicking noises as it is trying to LOCK the doors, but only once in 100 tries does it actually lock...and, yes, IT DOES SET THE ALARM 100% of the time, so my wife winds up opening the door and setting off the alarm.
