ABSTRACT:
In a magnetic key operated lock, a slide member carries a plurality of wheels in which are mounted magnetic pins. The position of the pins forms part of a code of the lock. The wheels are caused to rotate by insertion of a code changing key, which has a code for unlocking the lock, and moving the slide member. As the slide member moves, one of the pins which is repelled by the particular code changing key abuts a stop, which thus causes the respective wheel, and so the other wheels, to rotate. By having wheels of two different diameters, the smaller wheels can be made to rotate more than once before a code is repeated. The stops are formed by pressing a tang from a stationary wall in the lock.
