Abstract

A lock device has a lock lever changing from its locked position to its unlocked position by a normal-lock-motor, and a super lock member displaced between its super locked position preventing the lock lever from changing and a releasing position enabling the change. The lock device has a switch adapted to turn on when a key is inserted into the ignition key cylinder at the driver'"'"'s seat, another switch adapted to turn on when any person is in the interior of a car, still another switch adapted to turn on when any door opens, still another switch adapted to turn on when the trunk opens, and still another switch adapted to turn on when any window opens. When even one of these switches has turned on and the super lock member is changed to its super locked position, an alarm buzzer sounds or the change to the super lock halts.
