Welcome. There are 2 different procedures for programming these in your truck, and it depends on what GM calls luxury. So, I will give the first and easy one, try that and if that does not work, I post the second. You need a small piece of wire or a paper clip. Find the DLC port under the dash on the drivers side.

When reprogramming the remote control door lock receiver, All transmitters must be programmed at this time in order for the transmitters to operate the vehicle. Transmitters not programed at this time will not work and the procedure will have to be redone with all the transmitters.

  1. Ground pin 4 to pin 8 of the data link connector (DLC). The terminals are numbered 1 to 8 left to right top row.

    The receiver will respond by locking and unlocking the doors, and activating the liftgate window release (if equipped) within 2 seconds.

  2. Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed until the locks cycle (approximately 10 seconds).
  3. Repeat step 2 for up to four total transmitters to be programmed (if available).

    The receiver will respond by locking and unlocking the doors and activating the liftgate window release (if equipped) within 2 seconds.

  4. Remove the ground applied to the DLC.
  5. Lock and unlock the doors in order to verify the transmitter operation.
  6. Activate the rear window release in order to verify the transmitter operation.
