The present invention refers to a closure system which consists of lock and several keys in which the closing of the lock determined by mechanically or magnetically controllable tumblers is variable in such a manner that the closure code of the lock which corresponds initially to the coding of the first key can be varied by rearrangement of at least one tumbler member within the lock, to the coding of a successor key, and it proposes, with elimination of actuation of a tool or hand knob, that the displacement of the tumbler member be effected by means of the corresponding successor key in the manner that the successor keys are divided into a first region (A) associated exclusively with a closure code of the tumblers and a second supplementation region E which enters into action when the first region agrees with the closure code of the tumblers, and which shifts the tumbler member into the position acted on by the supplementation region of the next successor key.
