Abstract

A method for creating a key and a female lock part for a lock, whereby just a few parts are used to create a high number of unique locks. A coding part and a blank are affixed to each other to create the key or female lock part. Coding part and blank each have a contact surface, which, when brought together, can rotate continuously relative each other. The coding part is placed on the blank at a desired rotational position and affixed in that position, either by welding or adhesively. To create a lock with a unique lock function, two coding parts with mating contact surfaces are each attached to a blank, The key and female lock part so made function only with each other. In this way, the same basic coding part and basic blank can be used to create a large number of different locks.

Dependent claims

A method for coding a lock part for a lock in a locking system, the lock part being a key or a female lock part, the method comprising the steps of:

(a) providing a blank;
(b) creating a coding part that has a coding surface configured to interlock with a complementary shaped surface on the other one of the key or the female lock part;
(c) providing a contact surface on the coding part and a contact surface on the blank, wherein the two contact surfaces allow rotational movement relative each other after they are brought into contact with one another;
(d) selecting a desired rotational position of the contact surface of the coding part against the contact surface of the blank, wherein the desired rotational position may be any rotational position between zero degrees and three-hundred and sixty degrees;
and rotating the coding part and the blank relative to one another until the coding part and the blank are positioned in the desired rotational position;
and
(e) affixing the coding part to the blank while the respective contact surfaces of the coding part and the blank are in contact with one another, while maintaining the desired rotational position, the affixing being such that the coding part and blank cannot subsequently be pulled apart or rotated relative each other;
and
(f) machining the blank such that the machined blank is configured to actuate the female lock part or be actuated by the key.
