Can you cut a key from the number on the lock?
Yes — in many cases we can cut a new key just from the key code stamped on the blank or provided with your lock documentation.

For patented or restricted keys, we may need to see proof that you’re authorised to have them cut.
How long does key cutting take?
Most standard residential keys can be cut in just a few minutes.
