Keyless entry

[rbell219]

Our battery went dead suddenly in our 2000 Suburban. Now the keyless entry doesn't work. The panic button still sets the horn off and we've replaced the battery.

Anyone seen this/know the fix.

I would first try resyncronizing the remotes. This done by standing outside the vehicle (doors closed) and hold the lock and unlock buttons down (both at the same time) and holding them down for about 10 seconds. If successful, the door locks will cycle once. If that fails to do anything, they may need full reprogramming.

 

Here are the steps to reprogram the remotes...

 

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.

Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.

Repeat step #2 for each additional keyless entry transmitter.

Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.
