An 'extra' key can be made from a code machine if you know the cuts of the original. Rather than a duplicate key, this actually becomes an original key by code. Code machines have the feature of being versatile and the advantage of repeatable accuracy. The benefit is that you can generate a key to factory specifications every time.
NOTE: A code cut key is usually cut to the original equipment manufacturer's specifications. A duplicated key is cut to the depths of the pattern key.
While in a somewhat separate category, punch machines are non-motorized code cutters. These bench top machines are powered by pressing down on a handle. This Z-motion forces a punch through the key blade at a depth controlled by a dial or slide. Code clippers are also hand powered by squeezing two handles similar to a pair of pliers. Punch machines use a fixed punch profile to cut keys. Punches can be dedicated to cut one brand of key or may be flexible, allowing you to interchange brand-specific components.
Punches are lightweight and very portable. The benefit is that you can carry it anywhere and create a code key in seconds without electricity.
Tubular machines are made specifically for tubular keys and can fall into the duplicating or code cutting category. Tubular keys come in different diameters and pin positions. Standard tubular keys are .137" in diameter and utilize seven pins in a circular format. The pins are centered or offset from the 12 o'clock position of the tab. Offset left and offset right are still considered standard. Standard tubular duplicators should duplicate left, center and right keys. Other tubular machines may be required to handle other key diameters. Tubular code cutters can be motorized or hand cranked.
HIGH-SECURITY MILLING MACHINES
Milling machines are available as duplicators and as key originators. Duplicators will usually have a controllable carriage. This can be set to a fixed Z depth position while allowing a free-floating X and Y-axis. Center milled or side milled keys are duplicated by controlling the carriage movement with the joystick. Using the machine similar to a drill press duplicates dimple keys.
Key originating milling machine are usually electronic and quite expensive. These machines are designed for the higher security, mainly automotive market. Several of the key originating milling machines have many of the key codes already programmed into the on-board computer.
Milling machines use a variety of different cutter bits depending on the key being cut.
