Transmitter Synchronization

TRANSMITTER SYNCHRONIZATION

- Resynchronization may be necessary due to the security method used by the remote keyless entry system.The transmitter does not send the same signal twice to the Body Control Module (BCM).
- The BCM will not respond to a signal that has been sent previously.This prevents anyone from recording and playing back the signal from the transmitter.
- Resynchronization may be necessary under the following conditions:
- The battery in the transmitter is very weak.
- The battery in the transmitter was replaced.
- The battery in the vehicle has been in a low or no charge condition for an extended period of time.
- In order to resynchronize the transmitter with the BCM, perform the following steps:
1. Stand within 1.5 m (5 ft) from the vehicle.
2. Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for approximately 10 seconds.The door locks should cycle in order to confirm synchronization.
