Lock Cylinder Switch: Description and Operation
The Door Cylinder Lock Switch is used to:
-
Unlock/Lock all the doors via the Central Locking feature.
-
Arm/Disarm the Vehicle Theft Security System.
-
Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the rear of the driver and passenger door lock cylinders. When installed on the rear of the cylinder, there is a
tab on the lock cylinder that aligns with the switch to prevent it from turning. An anti-rotating device. The door cylinder lock switch is a one time use
switch. Once it is removed from the rear of the door lock cylinder, it may not be reinstalled and a new switch must be used.
When the Door Cylinder Lock Switch is turned either way using the door key cylinder, the BCM reads a direct message signal from the switch, via the
Programmable Communication Interface (PCI) bus.
If turning the key cylinder once, toward the front of the vehicle (for either driver or passenger doors), this will:
1. Mechanically unlock the door lock.
2. Disarm the Vehicle Theft Security System (if equipped).
3. 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 (either passenger or driver doors) 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. Furthermore,
this will arm the vehicle theft security system and turn OFF the illuminated entry.
