ABSTRACT:
An electronic lock cylinder comprises a housing (1) with a cylinder core (9) disposed rotatably therein and lockable by a key (15) via mechanical tumblers (21). Electronic control circuits (45, 47) capable of being coupled inductively via coupling coils (43, 49) for the transmission of coding information, are associated with the lock cylinder and the key (15). The coupling coil (43) of the lock cylinder, and the electronic components included in the lock cylinder and a mounting (51), are combined into a structural unit which is removably attached to a front face of the lock cylinder. This permits separate assembly of the mechanical components and of the electronic components of the lock cylinder.
