How Do Automatic Key Cutting Machines Work?
Automatic key cutting machines take much of the manual skill out of duplicating keys, producing accurate copies quickly and consistently.
How They Work
- Clamping: the original key and a blank are held securely in jaws or clamps.
- Tracing or decoding: the machine uses a mechanical guide (tracer) or, on some models, an optical or electronic sensor to read the shape and cuts of the original key.
- Cutting: a cutting wheel or cutter replicates the pattern onto the blank as the carriage moves, producing a duplicate.
- Finishing: the new key is deburred and tested.
Automatic vs Manual Machines
Manual duplicators rely on the operator to guide the carriage, while automatic machines move the key and cutter for you, improving consistency and speed. Electronic code machines go further, cutting keys by code without an original.

Frequently Asked Questions
Are automatic key machines accurate?
When calibrated properly, they produce consistent, accurate duplicates.
Can automatic machines cut car keys?
Some can, depending on the machine and jaws; laser-cut automotive keys usually need a code machine.
Do I need an original key?
Duplicators need an original; electronic code machines can cut by code.
