How to Program a GMC Key Fob
Whether you get a new key fob or your key fob simply stops functioning correctly, you may find that you need to reprogram your GMC key fob for use with your vehicle. Luckily, GMC has built features into their vehicles that allow you to reprogram the key fob yourself without having to take the vehicle to a dealership.
- Insert your key into the ignition and turn the key slowly until you reach the "Accessory" setting. You do not need to turn the vehicle's engine on in order to program your key fob. Programming the key fob only requires that the car's computer be able to communicate with the key fob.
- Press and hold the odometer's trip meter reset stem until the instrument panel displays "Relearn Remote Key." Release the odometer's trip meter reset stem. This should only take a few seconds. If it does not display after 30 seconds, release the stem and try again.
- Press and hold the odometer's trip meter reset stem again until the instrument panel displays "Remote Key Learning Active." Release the odometer's trip meter reset stem.
- Press and hold the "Lock" and "Unlock" buttons on the key fob simultaneously. Release the buttons when you hear a chiming sound. The timing for this can vary because the fob and your car are communicating with each other in order to program the key fob. If you have more than one key fob to program, you will need to start over with Step 2 for each fob.
- Turn off the vehicle completely when you are finished programming all of your key fobs.
