A device for opening and closing an electrically operated lock by means of a key, the lock incorporating a lock frame 1 and a door-locking blocking member 10, which is fitted in the said lock frame such that it can turn and, in normal operation, moves with an electric activator. The lock frame incorporates, placed in the hole line of the key, one or more obstruction plugs 23, having a special keyhole shape 26 and variously hung external threads, and further incorporates one or more obstruction holes 25 in the hole line of the key, a plate 4 fixed in the blocking member 10, which plate, by means of the key, transfers the opening function to the blocking member, and a non-rotary retaining plate 9, which locks the blocking member in non-rotational securement and can be moved by means of the key away from the locking position in order to execute the opening. <IMAGE> |
