Door Lock Cylinder
| Refer to COMPONENT INDEX . |
The door lock cylinder is a mechanical device allowing the customer to unlock or lock the vehicle with a bladed key.
Centralized locking or unlocking using a bladed key is available. The movement of the key cylinder on the driver door handle is detected by a switch connected electrically to the BCM. If the vehicle is being manually locked or unlocked using a bladed key inserted into the key cylinder, the BCM acquires the variation of resistance level and actuates the lock/unlock motor accordingly.
