Abstract
A lock with locking function released by inserting a key card with a magnetized region, in which the end edge (8') of the key card (8) drives a slide (25) which is released by the magnetic tumbler pins (31). There is at least one member which is displaceable by the movement of the slide, one end of the member scanning a profile of the key card (8). The member comprises a pin (62) which is tapered on both ends, the pin being displaceable parallel to the tumbler pins (31) in a borehole (61) in the slide (25) within a region which is free of the magnetic tumbler pins (31).
