Transmitter Synchronization

When transmitters are out of synchronization, all of the buttons except the fuel door release will be inoperative. Possible causes of a transmitter being out synchronization are; 256 button presses out of range of the vehicle, replacing the transmitter battery, and performing the synchronizing procedure out of range of the vehicle.
1. Press and hold the lock and unlock buttons simultaneously on the transmitter being synchronized for 7 seconds. All doors lock and then unlock to provide feedback that the synthesizing is complete.
2. Check transmitter operation.
