Programming your key fob transmitters

This is the procedure to program the key fob door lock and panic button transmitters on your 1999+ Silverado & Sierra pickups

Note: You must program all of your key fob transmitters.  Re-programming one will disable the others unless you do this to each.

What to do:

  1. Close all doors on the vehicle
  2. Insert the ignition key
  3. Press and hold the door unlock switch. While holding the switch, cycle the ignition key ON, OFF, ON & OFF
  4. Release the door unlock switch.  The doors will lock and unlock to confirm the program mode
  5. On the first key fob, press and hold the LOCK and UNLOCK buttons at the same time.  Hold them for 15 seconds until the doors lock and unlock to confirm the programming of the transmitter
  6. Repeat step 5 for each of your transmitters (up to four)
  7. Turn the ignition to the RUN position to exit the programming mode
  8. Operate each key fob to ensure they were programmed successfully
