Abstract

The variable-combination lock can be actuated with a main key which can enable actuation by a secondary key, which is different from the first by at least one notch. A seat is made in the cylinder, for this purpose, in a position angularly displaced with respect to the pawl relative to the notch of different height, and this seat houses a ball with a diameter essentially identical to the difference in height between the notch of the main key and that of the secondary key. By means of a tool which can be inserted frontally into the cylinder and angular positioning of the cylinder by means of the main key, the ball can be transferred from the seat in the hole of the relative counter-pin to compensate for the difference in height of the notch of the secondary key and permit actuation of the lock by the latter. <IMAGE>
