Keyless Entry Transmitter Synchronization

NOTE: Resynchronization may be necessary due to security method used by remote keyless entry system. Transmitter does not send the same signal twice to Body Control Module (BCM) and BCM will not respond to a signal that has been sent previously. This prevents recording and playback of transmitter signal. Fuel door release button should still operate normally when system is out of synchronization.
NOTE: Resynchronization may be necessary under the following conditions: transmitter battery is very weak, transmitter battery was replaced, or vehicle battery has been in a low or no charge condition for an extended period of time.

To resynchronize transmitter with BCM, stand within 5 ft. (1.5 m) from vehicle. Simultaneously press and hold transmitter LOCK and UNLOCK buttons for 7 seconds. Door locks should cycle to confirm resynchronization.
