Unlock Driver Door Only

WARNING: This page is about a different car, the 2012 Chevrolet Captiva Sport. However, it is still accessible from the selected car via links, so may be relevant.

Momentarily press the UNLOCK button in order to perform the following functions:

Unlock the driver door only.
Illuminate the interior lamps for a predetermined amount of time or until the ignition is turned ON. 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.
Flash the park lamps.
