Abstract (en)
[origin: EP0129042A2] A lock (11) fitted to a door (10) is modified by inserting an appropriate key into the lock so that a handle (12) of the key protrudes from the lock and applying a control unit (14) to the door to cover and engage drivingly the handle of the key. The control unit is responsive to a magnetically coded key, by means of which the control unit can be set in a condition in which torque is transmitted from a knob (18) to the key.
