Abstract
A key positioning fixture facilitates the accurate duplication of double-sided key on a key cutting machine and includes a first key alignment element having an upper clamping element with a first clamping surface and a lower clamping element with a second clamping surface. A position control element engages the upper and lower clamping elements to control the spacing between the clamping surfaces to align the centerline of the key with the centerline of the first key alignment element. A second key alignment element engages the first and second sides of the key blade to maintain the key in a fixed position.
