Lock with alterable combinations and with a flow diagram, actuated by a key card or a plurality of part keys. The invention relates to a lock having a high number of combinations formed by the introduction of a deformable steel key card 9 having slots of different lengths. The bottom of each of these slots drives a dog 5 and thus causes the rotation of each wheelwork 6 with which a disc 12 is associated by screwing, thus making it possible to alter the combination. This disc has a plurality of notches 10', thus allowing combined openings. A roller 4 guides the card and ensures that the mechanism is protected. This lock can be adapted to all closing or control devices, access to which must be recognised and authorised. The card 9 can be replaced by a plurality of part cards; it can also be introduced from inside. <IMAGE>
