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 keyless entry system has the following main components:

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 either a lock or unlock 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.

(BCM MODE 2 ONLY) Momentarily press the UNLOCK button in order to perform the following functions:

(BCM MODE 2 ONLY) Momentarily press the UNLOCK button a second time within 5 seconds of the first press in order to perform the following functions:

(BCM MODE 1 ONLY) Momentarily press the UNLOCK button in order to perform the following functions:

Press the LOCK button in order to perform the following functions:

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 keyless entry system will not function.

The keyless entry transmitters do not require a manual synchronization procedure. If needed, the transmitters automatically resynchronize when any button on the transmitter is pressed within range of the vehicle. The transmitter will operate normally after the automatic synchronization.
