What is a rekey vs. a lock change?

Rekey a lock means we adjust the cylinder so old keys no longer work and new keys do. You keep your existing hardware and finish. Choose this when:

  • You moved and want control of access.

  • A key is lost or not returned.

  • Your locks match your style and work fine.

  • You want one key to open several doors.

Change a lock means we replace the hardware. Choose this when:

  • The lock is worn, damaged, or unreliable.

  • You want stronger security or a different style.

  • You’re upgrading to a smart lock or keypad.

  • The current lock is not compatible with rekey goals.

If you are unsure, we assess on site and explain the best path with clear pros and cons.
