The invention relates to a locking apparatus consisting of at least one lock and a plurality of assigned keys, which are formed as coded key cards, and, to achieve an apparatus which is as reliable as possible, proposes that each key coding (32) has an address code (33) which is assigned to at least one addressed byte of the store, the byte being able to take up at least two states (first and second state), which decide the locking authorisation or non-authorisation for locking of the key card used each time. <IMAGE>
