Ensure all doors of your 2000 GMC Sierra 1500 are fully closed.

Insert your key into the ignition of your 2000 GMC Sierra 1500.
-
Press and hold the power UNLOCK button located on the driver’s side door panel. Maintain pressure on the UNLOCK button and do not release it until instructed.

While holding the UNLOCK button, quickly cycle the ignition from ON to OFF twice. “ON” is the position just before starting the engine, and “OFF” is the position where you can remove your key. The sequence should be: ON, OFF, ON, OFF.
-
Release the power UNLOCK button on the driver’s side door panel. Upon releasing the button, listen for the vehicle to automatically lock and unlock the doors. This lock and unlock cycle indicates that your 2000 GMC Sierra 1500 has successfully entered programming mode.
- Important: If the door locks cycle before you release the UNLOCK button, the vehicle has not entered programming mode. You will need to remove the key, open the door, and return to Step 1 to begin again.

- Timing is Key: If you are unable to get the door locks to cycle at all in step 5, you might be turning the ignition key too quickly or too slowly. Try adjusting your speed and repeat from Step 1.
-
Once in programming mode, take your first 2000 GMC Sierra 1500 key fob and press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding both buttons until the door locks cycle again. This may take up to 30 seconds. The door lock cycle confirms that the key fob has been successfully programmed.
-
Repeat Step 6 for each additional 2000 GMC Sierra 1500 key fob you need to program.
-
After programming all key fobs, turn the ignition key to the ON position and then back to the OFF position to exit programming mode.
-
Remove the key from the ignition.
-
Test each 2000 GMC Sierra 1500 key fob to ensure they are working correctly. Programming is now complete.
