General Description

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. Keyless entry allows you to operate the following components:
^ The door locks
^ 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 RCDLR communicates with the Body Control Module (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 request to the BCM and the BCM performs the appropriate function.
