<p>The key has a copy-protected flat-profile body including a predetermined structure cross-sectional region, where grooves and/or counter bore sections (7) for coding are provided with long width and long narrow sides. The grooves extend parallel to each other and form a profile of the key, and the flat-profile body includes ribs (5) that are formed on a longitudinal broad side of the body. The ribs run parallel to the grooves, and are projected over an upper surface of the body, where a supplementary coding possibility is created at the bore sections via length and/or a position of the ribs.</p> |
