Rekey Locks - Flat Per-Lock Price, Quoted on the Phone

Trusted Rekey Locks Nationwide

Rekeying a lock means swapping the internal pins inside the cylinder so the old key stops working and a new key operates the same hardware. It’s the fastest, most affordable way to take control of who can unlock your door: after a move, a roommate leaves, a cleaning crew changes, or a key goes missing. Preston Locksmith & Security has handled our Rekey Locks in Los Angeles and rekey work across the United States since 2008. Our technicians arrive in uniform, background-checked, with a plain-English written price confirmed before a single tool leaves the bag. Need it done today?

Lock Rekey

Lock rekey is the process of changing the internal pin configuration inside an existing lock cylinder so a different key operates it, while the old key no longer turns. You keep your current hardware. We replace only the pins and springs inside. This matters when you move into a new home, lose a key, end a relationship, or simply don’t know how many copies of your key are floating around out there. Preston Locksmith & Security rekeys standard residential cylinders, deadbolts, and commercial locks. Pricing depends on cylinder type and whether we need to match multiple locks to one key. A straightforward single-cylinder rekey typically runs $65 to $110 per cylinder, with a written price confirmed before we begin. We stock pin kits for Schlage, Kwikset, Yale, Medeco, and Baldwin, so most jobs finish in under an hour.

When Old Keys Need to Stop Working

New house, new locks is a smart rule, but full replacement is rarely necessary. Rekeying achieves the same security outcome for roughly a third of the cost. Preston rekeys every exterior door in a standard home in about 60 to 90 minutes.

What Gets Replaced Inside the Cylinder

A rekey means new pins, new springs, and new keys. The outer housing, deadbolt, and strike plate all stay. That is why it costs less than a full lock replacement and leaves no visible change to your door hardware.

Locksmith Rekey

Locksmith rekey is the service you hire when a trained pro needs to reconfigure your lock cylinders on-site, quickly, and with a guarantee behind the work. This is not a DIY vs Professional Rekey Locks: What’s Safe to Do Yourself project you buy at a hardware store and hope fits. It is precision pinning done to the specific tolerances of your existing hardware. Preston Locksmith & Security has been doing locksmith rekey work across the United States since 2008. Every technician carries factory pin kits and a pinning kit calibrated for the brands we service, including Medeco, Mul-T-Lock, Yale, and Baldwin. A residential locksmith rekey usually runs $65 to $110 per cylinder. If you have high-security cylinders or a commercial key system, expect $110 to $180 per cylinder. The price is in writing before any work begins, and it is the same price on the invoice.

Why a Pro Beats a Rekey Kit

Big-box rekey kits cover a narrow range of Kwikset and Schlage locks and fail on worn or high-security cylinders. A pro can diagnose worn pins, rekey multiple brands in one visit, and cut keys that actually work smoothly. We rekey every lock and test every key twice before we call the job done.

Multiple Locks, One Visit

A locksmith rekey appointment can cover every door in the house plus a padlock or mail lock in one stop. You get one written price for the whole job, one live arrival time, and before-and-after photos of each cylinder. If something is not right, our 365-Day Done Right Promise brings us back free.

Rekey Door Lock

Rekey door lock work means changing the internal pins of any entry door lock so existing keys no longer work and new keys do, without replacing the visible hardware on the door. It applies to front doors, back doors, side doors, garage entry doors, and interior privacy locks. When you buy a house, move into an apartment, or lose track of a spare key, a door lock rekey is the cheapest way to restore full control of who can enter. Preston Locksmith & Security rekeys standard door locks for $65 to $110 per cylinder. High-security door locks from Medeco or Mul-T-Lock run $110 to $180 per cylinder. All pricing is confirmed in writing before we start, with no call-out surcharge added on arrival and no bill that swells between the estimate and the invoice.

Exterior vs. Interior Door Locks

Exterior entry locks matter most because they protect the whole property. Interior locks, like bedroom or office doors, can be rekeyed at the same time for consistency. We recommend one key for every exterior door and a separate key for interior privacy locks if you want distinction.

Matching New Keys to Existing Hardware

The finish and style of your door lock stays exactly as it is. Rekeying does not change the look of your hardware. The only thing that changes is which key turns the cylinder. If a lock is worn, rusted, or loose, we will tell you directly and quote a repair only if you want it.

Rekey Service

Rekey service is a flat-priced locksmith call that covers disassembly, re-pinning, reassembly, and testing of your existing lock cylinders, plus new keys cut on the spot. It is the service you book when you want the old keys dead and new keys working, with no hardware replacement. Preston Locksmith & Security performs rekey service on residential locks, commercial storefront locks, deadbolts, and padlocks. Standard rekey service runs $65 to $110 per cylinder. A full house with three exterior doors and a deadbolt or two usually lands between $195 and $440 total, depending on cylinder count. We give you the complete price on the phone before anyone is dispatched, and that price is the price on the invoice. The Relay Visibility Guarantee covers every call: live trackable arrival time, uniformed pro, and before-and-after photos.

One Visit, Every Door Done

A single rekey service appointment can cover every lock on the property. We walk the doors with you, confirm which locks need to stop accepting old keys, and price the entire job before picking up a tool. No hourly billing, no mystery line items.

What the Guarantee Covers

Every rekey service includes a written guarantee and a free second visit if the repair fails, no charge, no argument. That is the 365-Day Done Right Promise. It is stamped on every invoice, not hidden in fine print.

Keyed Alike

Keyed alike means pinning multiple locks so a single key operates all of them, while each lock keeps its own cylinder and hardware. It kills the keyring clutter: one key for the front door, back door, garage entry, and deadbolt. You can also key certain locks differently than others, like keeping an office file drawer separate from the main entry. Preston Locksmith & Security performs keyed alike work on standard and high-security cylinders. Basic keyed alike service for two to four locks runs $65 to $110 per cylinder plus a modest setup charge, typically $20 to $40 for the master keying math. We confirm the total in writing before work starts. This is a popular add-on when we rekey a whole house.

Which Locks Make Sense to Match

Most homeowners key every exterior door alike and leave interior bedrooms on their own key or unkeyed. Small businesses often key the front door and office doors alike while keeping the cash register or file cabinets separate. We map out your system with you before pinning anything.

Adding a New Lock to the System Later

If you add a new deadbolt or replace a door later, we can key that new lock into your existing system in one visit. Keep your key. Add the lock. We pin it to match. It is one more reason keyed alike is easier to live with than carrying five separate keys.

Rekey Deadbolt

Rekey deadbolt means changing the pins inside your deadbolt cylinder so a new key operates the deadbolt and all previous keys stop working. The deadbolt itself, the bolt throw, and the strike plate stay exactly as they are. It is the most common rekey job we do, because deadbolts are the primary security point on most entry doors. Preston Locksmith & Security rekeys standard single-cylinder deadbolts for $65 to $110 per deadbolt. High-security deadbolts from Medeco, Mul-T-Lock, or Baldwin may run $110 to $180 per cylinder. We test the bolt throw, the turn piece, and the key operation before and after rekeying, and we take before-and-after photos so you can see the work was done right.

Single vs. Double Cylinder Deadbolts

A single-cylinder deadbolt uses a key on the outside and a thumb turn on the inside. A double-cylinder uses a key on both sides. Both can be rekeyed, but double-cylinder deadbolts take a little longer and may fall at the higher end of the range. We flag any safety concerns with double-cylinder setups, especially on exit doors.

When the Deadbolt Needs More Than a Rekey

If the bolt is bent, the tailpiece is broken, or the cylinder is so worn the key jiggles, a rekey will not fix it. We check the deadbolt’s mechanical condition on every call and tell you plainly if a replacement is the better call. The rekey price is never inflated to cover repairs you did not approve.

Rekey House

Rekey house service covers every exterior lock in a residence, from the front door to the back door to the garage entry door, so one new key operates the whole house and all old keys are dead. It is the standard first step after buying a home, because you have no way of knowing how many copies of the previous owner’s key are floating around-something we cover in The Complete Rekey Locks Guide for Los Angeles Homeowners. Preston Locksmith & Security rekeys a typical home with two or three exterior doors for $195 to $440 total, depending on cylinder count and whether any high-security cylinders are involved. The full price is quoted on the phone before anyone is dispatched, and it is the price on the invoice. No call-out surcharge, no hourly billing, no surprises.

Moving In? Do This First

Before you unpack boxes or hang pictures, get the locks rekeyed. Previous owners, their kids, their pet sitters, their contractors: any of them could have a key. Rekeying the house costs a fraction of replacing every lock and takes about an hour.

Every Door, One Key, Done Right

We walk the property with you, verify every exterior door, and pin all cylinders to match a single new key. Then we test each lock twice and hand you the keys. If any lock fails within 365 days, the Done Right Promise brings us back at no charge.

Brands We Service

Preston Locksmith & Security carries factory pin kits and service tools for Schlage, Kwikset, Yale, Medeco, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware. We work on standard residential deadbolts every day, and our technicians train specifically on high-security cylinders. Medeco and Mul-T-Lock cylinders require special key blanks and pinning tolerances; we stock both and rekey them on-site without sending your lock anywhere.

Baldwin and Yale hardware is common in higher-end homes and older commercial buildings. We keep OEM pins and key blanks for both, so your rekey preserves the original finish and keyway. Whether you have a Medeco deadbolt, a Baldwin entry set, or any other make, we can rekey it and key it into a matching system.

Signs You Need a Pro Right Now

• You just moved in: You have no idea how many keys are out there for the current locks. Rekeying every exterior door the same day you get the keys is the fastest way to control who can enter.
• A key is lost or stolen: If a key with your address attached goes missing, anyone who finds it can walk in. Rekeying kills every copy of that lost key in under an hour.
• A roommate, tenant, or contractor moved out: People make copies. Even if they return a key, assume duplicates exist. Rekeying removes that variable entirely.
• Your key sticks, jiggles, or needs a wiggle: Worn pins or a worn key are the usual cause. A pro can rekey with fresh pins and cut new keys that turn cleanly, rather than copying a worn key that just wears the lock faster.
• You are down to one working key: That is a single point of failure. If that key snaps in the lock or gets lost, you are locked out. Rekeying lets us cut a full new set at the same time.
