Transmitter Synchronization

Resynchronization may be necessary due to the security method used by the RKE system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.

Resynchronization may be necessary if:
1. The battery in the transmitter is very weak.
2. The battery in the transmitter is replaced.
3. The battery in the vehicle is very weak.
4. The battery in the vehicle is replaced.
5. The battery in the vehicle is disconnected.

To resynchronize the transmitter with the receiver:
^ While standing within 1.5 meters (5 feet) of the vehicle, simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for seven seconds. The door locks should cycle to confirm resynchronization.
