Abstract (en)
[origin: WO2023041517A1] The key or key blank (2) has a ramp face (24) at the front. Said ramp face extends over more than half the key thickness, i.e., the ramp face projects from one of the flat sides, through the centre plane between the flat sides, to a front protrusion. The key or key blank has a particular contour at the front. In a projection perpendicular to the flat sides, the contour forms a central, straight first section at the front and a second, at least partially curved section towards one side, said second section extending as far as the narrow side and merging into same. This second section is set back relative to a uniform curve line. This shape of the contour means that the space for coding bores on the key is optimised, while at the same time it is ensured that the key does not have any sharp edges at the front.
