Remote door transmitter

Sounds odd that you'd have to re-program the transmitters. Have you replace the truck battery recently? Have you had problems with it?

Here's the program procedure:

1. Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once. 2. Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once. 3. Repeat step #2 for each additional keyless entry transmitter. 4. Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.

If that doesn't work, you may have a problem with the RKE module. It's not >2000 GMC Z71

You said controls on the door work fine. Did you try the passenger door? I recently had to have my right door module reprogrammed by the dealer under warranty (03 Chevy Z71). All of a sudden the transmitters stopped working and nothing on the passenger door worked (windows, locks, button lights). Just a thought.

Thanks alot Mike, They work fine now. I wasn't looking forward to taking the dash apart. By the way, I did not replace the battery or have it disconnected. My remotes just stopped working suddenly at a shopping center. Thanks again.
