ABSTRACT:
An electronic key identifier includes first and second opposing surface segment sensors which can be clamped into engagement with the opposite sides of the blade of an unknown key blank. Each side of the key blade includes collinear surface segments separated by one or more recessed segments. Electrical conductors within the surface segment sensors contact the raised surface segments and discharge electrical energy through the grounded key blade. Appropriate electronic circuitry interfaces the conductor of the surface segment sensor with a computer to generate an electronic image of the two key blade sides. By comparing the electrical image of the unknown key blade with a database of electrical images of known key blades, the unknown key can be identified to allow the operator of a key cutting machine to quickly complete the key identification process.
