What it is

Rekeying changes the pins inside a lock so that a new key works and every old key stops working. The lock stays on the door. A lock change replaces the lock itself, when it is worn or damaged, or when you want a different kind of lock.

We rekey and change locks for homes and businesses.

Do you rekey for landlords and businesses?

Yes. We rekey and change locks for homes and businesses.

How much does rekeying cost?

It depends on how many locks and what kind, so we give you a free estimate before we start.
