Remote Transmitter Synchronization

If a previously programmed remote transmitter stops working, stand within 5 ft. (1.51 m) of vehicle. Press and hold LOCK and UNLOCK buttons for 7 seconds. Body Control Module (BCM) will indicate synchronization by flashing parking lights, locking doors, then unlocking doors. If BCM does not indicate synchronization, check remote transmitter battery. Replace battery if necessary, then reprogram remote transmitter. See REMOTE TRANSMITTER  . If battery is okay, reprogram remote transmitter. See REMOTE TRANSMITTER  .
