Abstract
Methods, systems, and devices for decoding an angle-cut key are provided. A probe is positioned at a first position relative to the angle-cut key. A first depth reading is performed on the angle-cut key. The probe is displaced to a plurality of subsequent positions and performing a plurality of subsequent depth readings on the angle-cut key. A key map of the angle-cut key is generated based on comparisons performed on a set of depth readings, the set of depth readings comprising the first depth reading and the plurality of subsequent depth readings. A signal indicative of the key map is output.
