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 keyless entry system has the following main components:
• | 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.

Rolling Code
The keyless entry system uses rolling code technology. Rolling code technology
prevents anyone from recording the message sent from the transmitter and using
the message in order to gain entry to the vehicle. The term "rolling code"
refers to the way that the keyless entry system sends and receives the signals.
The transmitter sends the signal in a different order each time. The transmitter
and the RCDLR are synchronized to the appropriate order. If a programmed transmitter
sends a signal that is not in the order that the RCDLR expects, then the transmitter
is out of synchronization. This occurs after 256 presses of any transmitter
button when it is out of range of the vehicle.
