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.
