Abstract

A locking mechanism for lids, hoods, flaps and/or doors, especially in motor vehicles, which cooperates with a cylinder lock whose lock cylinder is provided with a lock part adapted to be pressed-in against the force of a spring. The lock part includes, at its cylindrical outer surface, a pressure pin which is swung by rotation from an operating position to a non-operating position. In addition to the pressure pin, a lug is arranged at the outer surface of the lock part adapted to be pressed-in. The lug is operatively connected with an additional locking mechanism in such a manner that the additional locking mechanism becomes operable only over a limited rotary range of the lock cylinder adjoining the inoperable position of the pressure pin--as viewed in the locking direction.
