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

Whole-house lock changes start from $69, 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.

When a lock change makes sense

Moving into a home

You don't know who still has a key from before. New locks (or a rekey) put you back in control of every key that opens the door.

Worn or damaged locks

Keys that stick, cylinders that turn roughly, or hardware damaged after a break-in attempt — replaced with new, tested hardware.

Upgrading hardware

Stronger deadbolts, keyed-alike sets, or smart and keypad locks fitted to your existing door.

Rekey or replace?

Both retire the old keys. The right choice depends on the condition of your hardware.

Rekey

Keeps your existing locks in place
Old keys stop working
Good when hardware is in solid condition
Usually the lower-cost option

Replace

New lock hardware fitted and tested
Right choice for worn, damaged or dated locks
Lets you upgrade grade, finish or key type
Needed when parts are no longer available

"Jonathan was a true professional. He promptly arrived at my home to fix my door lock issue. I had stripped screws from a current door lock that needed to be removed, which he did very easily. In addition, he installed my new door lock for me. This all took under an hour."

"Jonathan was amazing to work with. He was super responsive, quick to schedule, and showed up right on time in Reseda. He made the whole process really easy and was very friendly and professional throughout. He rekeyed all three of our doors efficiently and gave us very fair pricing, which we really appreciated. On top of that, he went the extra mile to make sure we had copies of the new keys before he left. Overall, a great experience — highly recommend Jonathan if you need a reliable locksmith!"

"Jonathan did an amazing job doing a high-security lock fix in Sherman Oaks. He was very transparent with the costs. He also showed me exactly what was wrong with it and how he was going to repair it. Furthermore, he was very detailed in making sure everything was done correctly before leaving. Highly recommended."

"Amazing service! Responded to my inquiry quickly and made the trek over an hour to Van Nuys to come repair my stuck front door lock at 10pm on a Sunday night. Extremely fair pricing! The repair even came with a one year warranty."
