Abstract

A lock has a cylinder (1) with a cylinder core (2) that incorporates tumbler holes (3) for the housing and core pins. The core pins are of different shape and diameter. One of the tumbler holes has a housing pin of diameter a. One of the other tumbler holes has a housing pin with a head of diameter b, and a shaft of diameter c. The largest diameter is directed towards the core hole, and c is less than a, and a is less than b.
