Door locks - locking and unlocking with a key
Cars with trunk protection system
Master Key
Additional key
The master key fits any lock. The additional key cannot open the trunk lid.
The material is based on data from the portal nissanbook
Therefore, to protect items locked in the trunk, leave only an extra key with the parking attendant after you have parked your car and are leaving it.
Since the doors and trunk lid can be locked without a key, you should always carry a spare master key in case you forget the key in the car.
