The keyless entry system allows the driver to do the following functions from outside the vehicle by using a hand held radio transmitter.

The transmitter operates in the UHF band. The transmitter sends digitally coded signals to the Remote Control Door Lock Receiver (RCDLR) when pressing any of the transmitter buttons.

The RCDLR detects and decodes transmitter signals. For locking, unlocking, remote compartment lid release and remote alarm commands the RCDLR sends messages, via the RFA serial data link, to the Body Control Module (BCM) to operate the door locks actuators, courtesy lights and remote alarm.

Door lock, lighting and rear compartment lid release systems can also be operated in the usual manner. For instance the door locks respond to the door lock switches.

The keyless entry system can be programmed with up to four keyless entry transmitters.

1. Remote driver door unlock: The driver's door unlock when pressing the unlock button on the keyless entry transmitter.
2. Remote all door unlock: All doors unlock when pressing twice (or more) the unlock button on the keyless entry transmitter.
3. Remote all door lock: All doors lock when pressing the lock button on the keyless entry transmitter.
4. Rear compartment lid release: The rear compartment lid opens when pressing the rear compartment button on the keyless entry transmitter.
5. Remote activation verification: The headlamps flashes and/or the horn sounds when using the keyless entry transmitter. Refer to Remote Activation Verification System Description for more information.
6. Remote alarm: The headlamps flashes and the horn sounds alternately for two minutes when pressing the alarm button on the keyless entry transmitter. Pressing the alarm button again within two minutes stops the remote alarm.

The Remote Control Door Lock Receiver (RCDLR) sends door locking and remote alarm command messages to the Body Control Module (BCM) through the RFA link.

The BCM may set these DTCs related to the keyless entry:
