Abstract

A method and system for identifying a key blank corresponding to a master key is provided. The system includes a housing. A first source of uniform light is fixed relative to the housing. A second source of uniform light is fixed relative to the housing and is disposed opposite the first source of uniform light such that the master key is disposable therebetween. The first and second sources of uniform light are operable to generate an image of the master key. A receiver captures the image of the master key. A control having a memory configured to store information on a plurality of key blanks identifies the key blank corresponding to the master key based on the captured image.
