Method and apparatus for aligning keys for cutting

摘要

An apparatus and method for determining a bitting pattern of a key comprising a housing used for optically outlining at least the profile of the blade of the key so as to form an image. The image is digitized and information created therefrom, including information about the width of the blade of the key at a plurality of selected longitudinal positions along the length to include the width of the blade at the location of at least one cut of the bitting pattern. The information about the bitting pattern of the key digitized can then be used to cut the bitting patten into a key blank. Alternatively, the information can be compared to stored information and the detected width of the blade adjusted at a location of at least one cut to be one of a plurality of predetermined widths from the manufacturer, thereby creating a regenerated bitting pattern of the key.
