Just moved in? Lost a key? A rekey changes the pins inside your locks so every old key stops working, for a fraction of the cost of new locks. Done at your door, in one visit.

Costa Mesa Locksmith
Here is a question every Costa Mesa homeowner should ask: who else has a key to your house? The old owners. Their cleaner, dog walker, and contractor. The tenant before you. A rekey erases all of them in about an hour, without replacing a single lock.
Rekeying means we open your existing lock cylinder and swap its pins for a new combination. Your old keys stop working instantly, and you walk away with fresh keys that only you hold. It works on most Schlage, Kwikset, Yale, and Baldwin locks, and it costs about $19 to $29 per lock, far less than new hardware.
Costa Mesa Locksmith is the licensed team behind Golden Locks Inc. (CA License LCO4446), trusted in 400+ five-star Google reviews. We rekey homes, rentals, and businesses across Costa Mesa every day, and we can key all your locks alike so one key opens everything.

If your locks are in good shape, a rekey gives you full control for the lowest price. These are the classic moments:

How rekeying works
Rekeying is a simple trade secret worth knowing. Inside your lock is a row of small pins. We swap those pins for a new set that matches a brand new key, and every old key, the one your seller kept, the one the last tenant copied, stops working that same minute.
Your locks stay on the door, so it costs far less than replacing them, and we can set every door in the house to work with one single key. Most Costa Mesa homes take under an hour: front door, back door, garage entry, and all.
Honest pricing
| Service | Typical price range |
|---|---|
| Service call (Costa Mesa) | $15 to $29 |
| Rekey per lock (standard) | $19 to $29 |

Ranges are per lock with the hardware you already own. If a cylinder is too worn to rekey, we show you why and quote a replacement before doing anything, most homes rekey cleanly.
How it works
Tell us how many doors and locks you have. You get a full quote before we come out.
The tech removes each lock, swaps the pins to a new combination, and reassembles it.
We test your old key to prove it no longer works, then hand you crisp new keys.
We key the locks alike and label your spares. The whole home usually takes under an hour.
Local & proud
Costa Mesa turns over homes fast, classic ranch houses in Mesa Verde and College Park, condos near South Coast Plaza, apartments along Harbor Blvd, Baker St, and Adams Ave. Every move-in is a rekey waiting to happen, and our techs handle them daily across 92626, 92627, and 92628.
Property managers love our system: one call rekeys the unit, documents the new key count, and keys the whole property to a simple plan. Homeowners love the price. And in older Eastside and Westside homes with original hardware, we rekey carefully to preserve locks that match the character of the house.
Good to know
A quality new deadbolt installed runs $120 to $200 per door. A rekey of your existing deadbolt runs $19 to $29. Across a five-lock home, that is the difference between a $110 to $160 visit and a $600+ hardware project, for the exact same result: old keys stop working, new keys are only in your hands.
Replace when the hardware itself is the problem, rust from the coastal air, a loose wobbly knob, a lock builders-grade cheap that a firm kick could defeat. Our techs carry Schlage and Kwikset replacements on the van, so if a cylinder turns out to be junk, you choose on the spot with real prices in front of you.

Good questions
Rekeying changes the pins inside your current lock so it works with a new key, the hardware stays. Changing a lock replaces the hardware entirely. Rekeying costs about a third as much and is the right choice when your locks are in good condition.
Most locks run $19 to $29 each plus the service call. A typical 5-lock home lands around $110 to $160 total, done in one visit of about an hour.
In most cases, yes, as long as the locks share a compatible keyway (common with Schlage and Kwikset homes). Keying alike is included in our rekey price.
Most pin-tumbler locks can, including Schlage, Kwikset, Yale, Baldwin, and many high-security cylinders. Some cheap or damaged locks cannot, we will tell you honestly and quote options.
About 10 to 15 minutes per lock. Most Costa Mesa homes are fully rekeyed within an hour of our arrival.
Rekey if the locks look and feel solid, it gives you the same security result for far less money. Replace if locks are rusted, loose, or you want to upgrade to smart or high-security hardware. We will give you a straight opinion at your door.
