TYPES
Types of residential key services
Each key service uses a different source for the cut.

Key duplication
A duplicate is cut from an existing key, so it matches the original cut. A worn original produces a worn copy, so the technician checks the source key first.
Code key cutting
Code key cutting uses the key code for the lock. The technician cuts a new key to that code when no original key is available.
Replacement key origination
Origination makes a key from the cylinder when no key and no code exist. The technician decodes the pin pattern and cuts a matching key. Some restricted keyways require proof of ownership before a key can be made.

- The key no longer turns the lock smoothly.
- A new key can be cut from a copy or a code.
Lock repair makes sense when
- The key works, but the cylinder is gritty or sticking.
- The keyway or pins are damaged.
- A correctly cut new key still does not turn.
