Learn to program the remote in your 2002 Subaru Impreza. This includes the WRX model.
Programming Instructions:
Unhook the car’s alarm, if it is equipped with one. Open the driver’s side door, sit inside, and then close the door. Insert the key. Turn it between “Lock” and “On” 10 times quickly. Leave it in the ignition.
Open and then close the driver’s door. Push “Lock” on the remote. You’ll hear the horn chirp. The remote is programmed.
