WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article.

Remote Keyless Entry (RKE) system is a supplementary vehicle entry device. Use RKE system in conjunction with a door lock key. Radio frequencies or discharged batteries may disable system.

RKE system entry allows operation of following components:

Driver's and passenger door locks.
Rear lift glass release.
Illuminated entry lamps.
Panic alarm (instant alarm).

Main components of RKE system are:

Body Control Module (BCM).
Remote Control Door Lock Receiver (RCDLR).
Remote transmitters.

RCDLR module communicates with BCM through keyless entry serial data circuit. Pressing any button on remote transmitter, sends a signal to RCDLR. RCDLR module interprets signal and sends a request over keyless entry serial data circuit to BCM. BCM performs appropriate function depending on which transmitter button is pressed.
