Abstract

L'invention concerne un ensemble clé destiné à être utilisé dans une serrure. L'ensemble clé comprend une tige (16) présentant une extrémité (30) de pointe et une extrémité (14) de tête. L'extrémité (14) de tête comprend une paire de pattes espacées opposées. Un insert (12) est placé entre les pattes espacées, et présente une paire de faces opposées (22). Un matériau (18) est surmoulé sur l'extrémité (14) de tête de la tige et au moins une partie de l'insert (12). Dans un mode de réalisation, au moins une partie d'au moins une des faces (22) n'est pas recouverte de matériau afin d'obtenir au moins une surface de marquage d'empreintes (24).
