4. Step-by-Step Guide to 2018 GMC Sierra Key Fob Programming

How do you program a key fob for a 2018 GMC Sierra? To program a key fob for a 2018 GMC Sierra, follow these steps: First, insert your key into the ignition and quickly turn it ON, OFF, ON, OFF. Then, press and hold the unlock button on the driver’s side door. The vehicle should enter programming mode, indicated by the doors locking and unlocking. Finally, press the lock and unlock buttons on the key fob simultaneously until the doors cycle again. According to GMC’s official instructions, this process should synchronize the key fob with your vehicle.

Close all doors.
Insert key into the ignition.
Press and hold the power UNLOCK button on the Driver’s side door panel. Do not release until instructed to do so.
Quickly turn the ignition ON, OFF, ON, OFF. (ON is the position just shy of starting your vehicle, OFF is the position where you can remove your key)
Release the power UNLOCK button on the Driver’s side door panel. Upon release of the UNLOCK button, the vehicle should respond by locking and unlocking automatically signaling programming mode has been reached. If the locks on your vehicle cycle, continue to Step 6. If the door locks LOCK and UNLOCK BEFORE releasing the UNLOCK button, the vehicle has NOT entered programming mode and you must start over (remove key, open door and return to Step 1). If the vehicle continues to LOCK and UNLOCK BEFORE releasing the UNLOCK button, there is a problem with the vehicle’s keyless entry system and the remotes must be programmed by a certified professional. If you are unable to get the door locks to cycle at all, you are turning the key too quick or too slow.
Hold the LOCK and UNLOCK buttons on the remote at the same time until door locks cycle again. This could take up to 30 seconds.
Repeat Step 6 for all additional remotes to be programmed.
After Step 6 has been performed for all remotes TURN ignition to ON to exit programming mode.
Turn ignition to OFF and remove key.
