Abstract

L'invention concerne une clé présentant une silhouette particulière qui comprend une découpe profilée (74) sur un premier côté de la tige (64) et une protubérance respective (72) sur le côté opposé de la tige. Cette clé coopère avec une serrure à cylindre permettant de piéger une clé non autorisée. La serrure comprend un pêne auxiliaire (50) coopérant avec la découpe de la clé et un élément plat amovible (34) coopérant avec la protubérance. La découpe et la protubérance doivent être correctement dimensionnées et profilées pour qu'une clé à profil fonctionne correctement dans une serrure.
