<p>The key has longitudinal grooves (2, 3) in key side surfaces, where an arrangement and a cross section of the grooves are variable for producing closing variations, and a cross-sectional shape of the grooves corresponds to triangle. A base side of the grooves lies in a key flat side (1) from which slotted sides extend to a crossing line, where one of the slotted sides forms the halve of the triangle. A shallow variation groove is formed such that one of the slotted sides have the half side length of the other slotted side, which extends from the key flat side upto the crossing line. An independent claim is also included for a cylinder lock with a key channel and a key.</p> |
