Full Answer

The process for reprogramming a GM remote keyless entry fob has been streamlined in recent years by GM to make it easier for people to do it themselves. However, it is still possible to go to the dealer and have them reprogram the fob for you in minutes for a set cost.

To reprogram the fob yourself, first get inside of the vehicle and make sure all the doors are closed. Insert the ignition key, and press and hold the "Unlock" button on the driver's side of the door. While holding the "Unlock" button, turn the ignition key to the "On" position, then "Off," then "On," then "Off" again in quick succession. Now, release the "Unlock" button, and the vehicle doors should lock.

Next, press and hold the "Lock" and "Unlock" buttons until the doors lock and unlock again. If you are reprogramming more than one fob, repeat this step for each fob. Finally, turn the ignition key to the "On" position for 10 seconds, which will exit the programming mode for the fob.
