Driver Cylinder Lock Switch: Operation

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

When the Door Cylinder Lock Switch is turned either way using the door key cylinder, the Driver Door Module (DDM) reads a direct message signal from the switch.

Turning the key cylinder once, toward the front of the vehicle, will:

Mechanically unlock the door lock.
Disarm the Vehicle Theft Security System (if equipped).
Turn on the Illuminated Entry (if equipped) for approximately 30 seconds.

If the key cylinder is turned to the unlock position (toward the front of vehicle) twice within two seconds, all the doors and liftgate will unlock (if equipped with the central locking feature).

To lock the vehicle using the door cylinder lock switch, turn the key cylinder toward the rear of the vehicle once. This will lock the door that you are using the key on. If equipped with the central locking feature, this will lock all the other doors and liftgate, arm the vehicle theft security system and turn off the illuminated entry.
