Abstract

A door lock system for a vehicle of which a striker, a first switch and a manual switching mechanism are mounted to the vehicle door and a first latch, a first motor, a second latch, a second motor, a second switch and a key cylinder are mounted to the vehicle body. When the key cylinder mounted to the vehicle body is switched to an unlock side, the second switch rotates the second motor, but the second latch remains engaged with the first latch. When after that the first switch is turned on by the manual switching mechanism on the door side, the first motor rotates and the first latch releases the striker.
