Method of manufacture of a key toothed as well as a key toothed obtained by this.

摘要

The present invention relates to a method of manufacturing a serrated key, characterised in that it comprises the following steps: - at least two identical flat side plates (1) are made up, on which, on at least one of their edges, regular teeth (2) are formed, - the teeth (2) are machined at predetermined sites (5a, 5b, 5c) in such a way as to create a serration specific to the key, - a flat central plate (6) is made up, with smooth edges (7) of the same width as the plates (1) which are fitted at each of its extremities with a hole (9), - the machined side plates (1) are assembled to the central plate (6).
