[ol]Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete. [/ol]
