There's a detachable key blade inside the standard key.
If your standard key or key tag isn't working, you can use this key blade to:
- open the left-hand front door
- activate and deactivate the child lock
- lock a door.
If you use the detachable key blade to unlock the car, you can deactivate the alarm and start the car by placing your key on the backup key reader.
The backup reader is located in the tunnel console's storage compartment.
