jimform2k1 Posted September 8, 2009 Report Share Posted September 8, 2009 Hello, I have a 2000 grand prix GT coupe. My fob is having trouble locking and unlocking the doors. Trunk button alWAYs works from the fob. It was doing this a few weeks ago, so I changed the fob battery, resynced by holding lock and unlock buttons. Got the horn beep to confirm sync. Now, fob lock button never works. Fob unlock button works sometimes. If I try to resync now, I get no horn beep but trunk button still works. If I press the lock button on the door, it auto locks the doors after a few seconds. Would disconnecting the car battery for awhile help? Any other ideas? Thanks Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 8, 2009 Report Share Posted September 8, 2009 I would start with a new keyfob. Quote Link to comment Share on other sites More sharing options...
Addicted2bass Posted September 8, 2009 Report Share Posted September 8, 2009 Or try cleaning the contacts on the fob you have. Quote Link to comment Share on other sites More sharing options...
Galaxie500XL Posted September 9, 2009 Report Share Posted September 9, 2009 X2 on the cleaning. One of the fobs for my Cutlass did that when I bought it. The button was full of pocket lint! Quote Link to comment Share on other sites More sharing options...
