Abstract
A key identifier enables an operator to select a key blank design functionally compatible with an unknown key by directing the operator to implement a primary classification step followed by a secondary classification step to sort an unknown key into a specified secondary classification category. The key identifier operator then implements a key blade matching procedure within the specified secondary classification category where the cross section of the blade of the unknown key is matched with a defined blade cross sectional configuration. When a match is obtained between the unknown key blade configuration and the known blade configuration, the known key blank design can be identified and a compatible key blank can be selected.
