Transmitter Programming

WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

Important: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 2 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
Use the scan tool in order to access the Body Control Module (BCM) Special Function: Program Key Fobs menu.
Important: The scan tool must stay connected until all of the transmitters are programmed.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 15 seconds, the BCM will chime in order to confirm the programming of that transmitter.
Repeat the previous step in order to program up to 2 transmitters.
Remove the scan tool.
Operate the transmitter functions in order to verify correct system operation.
