I was wondering if anyone had any luck in reprograming the transmitter on a 1994 GMC Jimmy? My daughter dropped the old remote and lost the little ground wire that grounded the batteries. Needless to say, after spending $70.00 at the local GM dealer, I do not want to waste any more buck there. The number on the new remote is ABO0104T.
Thanks,
Rick

The control module will respond by locking/unlocking doors and activating rear window release.
