Remote Keyless Entry (RKE) Transmitter Synchronization

If a previously programmed RKE transmitter stops working, stand within 20 ft. (6.1 m) of vehicle. Press and hold LOCK and UNLOCK buttons for 8 seconds. Body Control Module (BCM) will indicate synchronization by flashing interior lights, locking doors, then unlocking doors. If BCM does not indicate synchronization, check RKE transmitter battery. Replace battery if necessary, then reprogram RKE transmitter. See REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING  . If battery is okay, reprogram RKE transmitter.
