ABSTRACT:
A closure system 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 a 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 element (28) within the lock, in response to the coding of a successor key. This negates need for a tool or hand knob. Displacement of the tumbler element (28) be effected by means of the corresponding successor key (36) in the manner that successor keys (36) 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. This shifts the tumbler element (28) into the position acted on by the supplementation region of the next successor key.
