General Information

The keyless entry system is a supplementary vehicle entry device. Use the keyless entry system in conjunction with a door lock key. Radio frequencies or discharged batteries may disable the system. Therefore, always carry a door lock key.

Keyless entry allows you to operate the following components:
^ The door locks
^ The rear compartment lid release
^ The illuminated entry lamps
^ The panic alarm (instant alarm)

The keyless entry system has the following main components:
^ The transmitters
^ The Remote Control Door Lock Receiver (RCDLR)
^ The Body Control Module (BCM)

The RCDLR communicates with the BCM through the keyless entry serial data circuit. When you press a button on a transmitter, the transmitter sends a signal to the RCDLR. The RCDLR sends a lock, unlock, or panic alarm request to the BCM depending on which button is pressed on the transmitter. The BCM receives the message from the RCDLR and performs the appropriate function.
