Abstract
A locking device includes a lock and key and has tumblers which can be brought by a key into a release position, and provides, in particular, for a large number of closing combinations, that at least one of the tumblers can be brought, in addition or alternatively to its direct control by the base code of the corresponding key, by means of a magnet coil into a release position. The coil is energizable by a reading device which detects at least one supplementary code of the key.
