Most fobs have two halves that snap together -You’ll need to pull the sides apart in order to access the battery. You’ll typically need a small screwdriver or some other tool that has a flat, thin blade. It’s a good idea to look for a notch along the lower edge of the fob that you can wedge your tool between. You may also want to look for small pieces that may fall off while working.

The basic procedure is simple. Make sure that the battery is securely in place. Then, get in the driver’s seat, and close all doors, excluding the driver’s side door. This will ensure the new fob is communicating with the vehicle correctly. Then, place the old key back into the ignition and turn it on to the ON position, but do not start the engine. Next press the lock button on the fob, while aiming it at the transmission receiver, which is typically located in the front of the vehicle above the mirror. The key will signal to the vehicle within a short amount of time that it’s being programmed. This can be accomplished by cycling the door locks, or emitting an audible chime.
