<p>A closure system has card keys (K) to be handed out provided with a code and whose broad side surfaces are subdivided into individual fields (E) that can be magnetically coded in distinct manner for each lock/card holder. These individual fields (E) move into the open position magnetic locking pins (31) which are accordingly positioned and which act as tumblers for the lock (4). In order to enlarge the range of possible applications, a service station (SA) changes the coding of data identification individual fields (E1) of the key (K), so as to increase or reduce their value, and an evaluation station is provided with a reading device for acquiring and storing such changes of code in association with other codes of the card key (K).</p> |
