Key duplication

Key duplication refers to the process of creating a key (lock) based on an existing key. Key cutting is the primary method of key duplication: a flat key is fitted into a vise in a machine, with a blank attached to a parallel vise, and the original key is moved along a guide, while the blank is moved against a wheel, which cuts it. After cutting, the new key is deburred: scrubbed with a metal brush to remove burrs which, were they not removed, would be dangerously sharp and, further, foul locks.
