Abstract
A system and method for identifying a key blank from a master key is provided. The system includes a housing, a first source of uniform light fixed relative to the housing, and a second source of uniform light fixed relative to the housing and disposed at an angle relative to the first source of uniform light. A reflecting device is proviced that has a reflective surface and a transparent surface. The reflecting surface is configured to reflect light generated by the second source of uniform light towards the first source of uniform light such that when a master key is disposed in the housing, the first source of uniform light generates a profile image of the master key and the second source of uniform light illuminates a surface of the master key. A receiver is operable to capture an image of the master key through the transparent surface of the reflecting device.
