Remote Control Door Lock Transmitter

The remote control door lock transmitter transmits a radio signal to the body control module (BCM). The BCM controls the functions of the transmitter. The transmitter range is approximately 9 m (30 feet). The transmitter data is encrypted, and changes with each use. If the transmitter buttons are pressed too many times out of range from the vehicle the transmitter and the BCM will get out of synchronization. This will result in the transmitter appearing not to work at all. This situations will occur after the transmitter button is depressed more that 256 times when it is out of range from the vehicle. This may also be necessary if the transmitter battery has been replaced and the buttons were pushed a few times out of range. If the transmitter and the BCM get out of synchronization, re-synchronize the transmitter and the BCM. Refer to Transmitter Programming/Synchronization
