摘要： A centralized door-locking system in a motor vehicle in which all of the doors of the vehicle and a tailgate of the vehicle have lockable latches which can be locked/unlocked electrically using key-operable switches asociated with the lockable latches in the driver's door, front passenger's door and the tailgate of the vehicle. In the system, it is possible to selectively lock/unlock the driver's door and/or the tailgate independently of the remaining doors of the vehicle, thus improving the overall security against unauthorized entry to the vehicle by third persons during usage of the vehicle. This selective locking/unlocking of the driver's door and tailgate may be achieved by using, for example, a key-operable switch in the driver's door having a rotatable key barrel 32 with key slot 160 which is rotatable clockwise or anticlockwise from a central position N to sequential switching positions A and B, or C and D, against an increasing spring bias 162, 164. In such an arrangement, movement of the key slot 160 from position N to position A mechanically unlocks only the driver's door, whereas movement of the key slot from position A to position B electrically unlocks all of the doors and the tailgate of the vehicle.
