Key duplication machines work by using a guide, called a tracer, to follow the shape of the original key while a cutting wheel simultaneously carves an identical pattern onto a blank key. The original key and the blank key are securely clamped in parallel, ensuring that the duplicate matches the original’s grooves and notches. This process creates a copy that can operate the same lock as the original key.
