Transmitter Synchronization

Synchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice. The Body Control Module (BCM) will not execute a signal if it has been sent previously. This eliminates the possibility of the signal being recorded and played back.

IMPORTANT: If the transmitter(s) won't work, perform the RKE SYSTEM CHECK before synchronizing the transmitter(s).

To synchronize a transmitter with a BCM, simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter, for approximately 10 seconds, near your Saturn. The door locks will cycle to confirm synchronization.

IMPORTANT: If the transmitter(s) is programmed to more than one Saturn, each Saturn must be within transmitter range during synchronization. Otherwise, the transmitter(s) will not work for the Saturn that is out of range.
