Keyless Entry System Description and Operation: Notes

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, including the rear compartment.
• The illuminated entry lamps
• The panic 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.
