Transmitter Synchronization

When transmitters are out of synchronization, all of the buttons except the panic button will be inoperative. The following conditions are possible causes of a transmitter being out of synchronization:
^ 256 button presses out of range of the vehicle
^ Replacing the transmitter battery
^ 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, within 1 meter from the vehicle. All doors lock and then unlock in order to provide feedback that the synchronization is complete.
2. Verity transmitter operation.
