In a method and apparatus for measuring an original key, a line of the light is focused onto the key surface in a direction perpendicular to the key surface. A camera, or other type of detector is disposed to receive light deflected by the key at an oblique angle. The keyway and keycode of the key can be determined from the deflected pattern of light.
