Abstract

A locking means for a trunk in an automobile is disclosed which can be unlocked by the rotation of a key inserted in a key cylinder of the trunk and which comprises a first switch provided at a proper location in the room of the automobile to open and close a D.C. circuit including an actuator means for unlocking the locking means. A second switch which is usually closed is provided in said D.C. circuit in such a way as to be opened by the rotation of said key inserted in the key cylinder of the trunk in a direction contrary to that for unlocking the locking means, thereby it becomes possible for a proprietor of the automobile who stands outside the automobile near the trunk to actuate the second switch so as to prevent the opening of the trunk by any other person against the will of the proprietor.
