Abstract

A system for duplicating a master key includes a clamping mechanism for receiving and positioning a master key. The master key defines a major key axis and an intermediate key axis along which a key blade variably extends. The key blade has an upper surface and a minor key axis along a key thickness. A mechanical measurement device includes a probe that deflects along the intermediate key axis during a measurement process. A movement mechanism imparts relative motion along the major key axis between the mechanical measurement device and the master key. The mechanical probe follows the upper surface of the key blade. The mechanical measurement device generates a signal indicative of the deflection of the probe. A processor receives the signal and generates information usable for defining the machining of a duplicate key.
