How much does it cost to change all the locks on a house?

For whole-house lock changes, get an estimate on the phone before we come out, and the total depends on how many doors you have and whether you rekey or replace. We give you a clear, free estimate over the phone and confirm the price before starting.

Should I rekey or replace every lock when I move in?

If the existing locks are in good shape, rekeying every exterior door is the fastest, most affordable way to invalidate all old keys. If hardware is worn or you want an upgrade, replacement is worth it. We'll recommend the best mix for your home.

Can you put every door on one key?

Yes. We can key all your exterior locks alike so a single key opens every door — a popular convenience upgrade when changing the locks on a house.

Do you handle rental and Airbnb turnovers?

We do. We rekey between tenants and guests and can install smart locks with changeable codes so you never have to hand off physical keys for short-term rentals.

How fast can you change my house locks?

We confirm an arrival window when you call and secure the whole house in a single visit.
