Non-destructive entry first, always - and we re-key Schlage, Kwikset, and Baldwin locks on the spot while you watch
You get a price before we start. It does not change when we arrive. No surprises.
Trusted Residential Locksmith Nationwide
When a lock fails, a key snaps, or a deadbolt won’t throw, the fix almost always comes down to one thing: getting a trained pro to your door with the right tools and a price you can hold them to. Preston Locksmith & Security has handled residential lock work since 2008, and every job runs on The Relay Visibility Guarantee: a written price before any tool leaves the bag, a live trackable arrival time, before-and-after photos, and a written guarantee on every repair. That means no four-hour waiting windows, no price that changes between the estimate and the invoice, and no anonymous technician showing up at your door. Call (409) 405-4485 any hour and a live person answers, not a voicemail tree.
House Lockout
House Lockout is the moment you realize your keys are on the other side of a locked door, and every minute you stand there is a minute stolen from your day. We get it, and we get there fast. A Preston Locksmith & Security technician arrives in a marked vehicle, confirms you’re authorized to be at the property, and picks or bypasses the lock without damaging the door frame, weatherstripping, or hardware whenever possible. A standard house lockout typically runs $75 to $180, with the written price confirmed by phone before dispatch so there’s no surprise on arrival. For a quick refresher on how our broader home services fit together, that’s your starting point.
What the technician checks first
Before forcing anything, the tech inspects the lock cylinder and strike plate to find the least invasive entry point. Most deadbolts and knob locks can be picked clean, preserving the original hardware and keeping your existing keys working.
After you’re back inside
Once the door is open, the technician tests the lock through a full cycle: throw, retract, key-in-key-out. If the cylinder is worn or the latch is dragging, you’ll get a straight recommendation and a written price for any fix, with zero obligation.
Deadbolt Installation
Deadbolt Installation puts a hardened steel bolt into the door frame itself, which is why a properly installed deadbolt stops a shoulder-shove where a spring-latch knob fails. Preston Locksmith & Security installs single-cylinder and double-cylinder deadbolts, reinforces strike plates with longer screws into the framing, and bores fresh holes in doors that lack existing prep. A standard deadbolt installation typically runs $120 to $260 including the lock and labor, with the exact written price confirmed before work begins. Our techs regularly install Yale and Baldwin deadbolts, and keep common Schlage and Kwikset models stocked for same-day work.
Strike plate reinforcement
The weak point in any deadbolt is rarely the lock, it’s the shallow screws in the strike plate. We replace them with 3-inch hardened screws that reach the stud behind the jamb, so the deadbolt is doing its actual job.
Double-cylinder explained
A double-cylinder deadbolt uses a key on both sides, which can make sense for doors with glass panels within arm’s reach of the thumb turn. We’ll walk through the tradeoffs so you can decide with a clear head, not a sales pitch.
Locksmith Key Replacement
Locksmith Key Replacement is cutting a new key from the lock itself or from an existing key, so you’re never stuck with one worn, bent original that’s a snapped-in-the-cylinder accident waiting to happen. Preston Locksmith & Security cuts standard house keys on-site and can originate keys for high-security brands like Mul-T-Lock that require a special blank and a key card. Replacing a standard key typically runs $8 to $30 per copy, while a lost-key replacement that involves decoding the lock runs $35 to $90 per cylinder. The written quote is always in your hand before the first key is cut.
Worn key warning sign
If your key takes a wiggle and a pull to come out of the lock, that’s not a personality quirk, it’s wear on the cuts. A fresh key cut by code, not copied from a worn original, restores clean operation and protects the cylinder from damage.
High-security key duplication
Mul-T-Lock and other high-security brands use side pins and restricted keyways that a hardware-store machine can’t duplicate. We hold the specialized blanks and machinery to cut these keys accurately, and we verify each one in a test lock before it leaves the van.
Smart Lock Installation
Smart Lock Installation replaces your mechanical deadbolt with a keypad, fingerprint, or app-controlled lock, so the question “did I lock the door?” gets answered from your phone instead of a panicked drive home. Preston Locksmith & Security installs smart locks from major brands, checks door alignment and backset measurements before any hardware is touched, and pairs the lock with your phone or keypad so it works the same day. A smart lock install typically runs $150 to $350 including labor, with the written price locked before work starts. We’ve also done hundreds of door lock repair jobs on doors where the prep work needed adjusting first.
What makes an install last
A smart lock only operates as smoothly as the door it’s mounted on. We square up the strike plate, adjust the deadbolt throw, and confirm the motor isn’t fighting a misaligned latch, because a binding install kills batteries and motors within months.
Brand and compatibility advice
Not every smart lock fits every door or every phone. We check your existing deadbolt type, door thickness, and whether you need Wi-Fi, Z-Wave, or Bluetooth, then recommend a model that matches how you actually use your door.
Locked Out of Apartment
Locked Out of Apartment means standing in a hallway or parking lot while your keys sit on the kitchen counter, and it never happens at a convenient hour. Preston Locksmith & Security responds to apartment lockouts around the clock, and we handle the extra step most people forget: coordinating with building management or property staff when a building access key or lock change permission is required. An apartment lockout typically runs $75 to $180, with the price written and agreed by phone before a technician is dispatched. A live person answers 24/7, so you’re never explaining your situation to an automated greeting.
Property manager coordination
Many lease agreements require a lockout to go through the leasing office or a designated locksmith. We’re familiar with that process and will confirm the protocol with you before we touch the lock, so you don’t end up with a lease violation for getting back into your own unit.
Non-destructive entry
Our technicians pick apartment locks rather than drill them whenever the hardware allows. That keeps your deposit intact and means the building’s keyed system keeps working for everyone else in the complex.
Apartment Locksmith
Apartment Locksmith work is a different animal from single-family home service, because the lock may be part of a master key system, the door may be hollow-core, and the lease may limit what can be changed without written consent. Preston Locksmith & Security knows these constraints and works within them: we confirm ownership and permission before any rekey or replacement, and we document every job with before-and-after photos that protect both you and your landlord. Apartment rekeying typically runs $25 to $40 per cylinder, while a lock replacement runs $90 to $180 per lock, always with a written price first.
Master key system compatibility
If your building’s maintenance staff carries a master key, a random rekey can break that system. We cut tenant keys and match cylinders so the master key still works, which keeps you legal and keeps maintenance from locking you out later.
Lease-compliant lock changes
Some leases forbid changing locks without providing a key to management. We’ll rekey to new keys and produce a labeled set for the office, so you get new keys without breaching your agreement or creating a lockout down the road.
Lost Key Replacement
Lost Key Replacement is what you need when the key isn’t just misplaced, it’s gone, and you have no way of knowing who might have it or where it might turn up. Preston Locksmith & Security handles it two ways: we can cut a new key from an existing copy, or, when security matters more than cost, we rekey the lock so the lost key stops working entirely. A replacement key runs $8 to $30, while a full rekey with new keys runs $25 to $40 per cylinder. The sensible move after losing a key with any identifying information is a rekey, and we’ll quote that as a flat per-cylinder price before anyone is dispatched.
Rekey vs. replace after a loss
If the lost key has no tags and was dropped somewhere untraceable, a new key may be enough. If it was on a keychain with your address, a rekey closes the gap entirely and takes about 15 minutes per lock.
Documenting what was changed
We photograph every cylinder before and after the work, and you get a digital invoice with a pay link showing exactly what was rekeyed, how many keys were cut, and the guarantee on the repair. No paper mystery, no unstated charges.
House Key Locksmith
A House Key Locksmith is the person who makes, copies, or rekeys the keys that get you through your front door, and a good one saves you the trip to a kiosk that chews up blanks and spits out a key that works twice before it dies. Preston Locksmith & Security cuts house keys from original keys or from code, decodes worn cylinders to originate a fresh key, and rekeys existing locks so old keys stop working without buying new hardware. A standard house key copy runs $8 to $15, while a rekey with new keys runs $25 to $40 per cylinder. We come to you, so there’s no second trip and no guessing at a self-serve machine.
Cut by code, not by copy
Every copy of a copy drifts further from the original cuts, until the key just stops working one day. We can read the existing key or the cylinder and cut a fresh key to factory spec, which often fixes a key that binds or sticks.
Replacing a worn cylinder along the way
Sometimes the key is fine and the lock is the problem. If the cylinder is too worn to decode reliably, we’ll show you the issue with photos, quote a replacement like our rekey locks service as an alternative, and let you choose the most cost-effective fix.
Brands We Service
We stock and service Medeco hardware, including its high-security cylinders that use rotating pin systems and restricted keyways. Duplicating a Medeco key requires a special key card and a dealer-level blank, both of which we keep on hand, so you’re not waiting on a mail-order blank to get a spare key. We also carry Yale deadbolts and entry locks, and our technicians are trained on Yale’s newer keyless and smart lock integrations, which means we can service the lock and the electronics without calling in a second trade.
Baldwin hardware shows up on a lot of higher-end front doors, and it has its own spindle and latch tolerances that a generic installer can strip or misalign. We’ve serviced enough Baldwin locks to know when a part can be rebuilt and when the mortise body needs replacing, and we keep the common replacement parts on the truck. Mul-T-Lock cylinders use telescoping pins and a key card the owner must present for duplication, and we hold dealer credentials to service them properly. Whether you have Medeco, Yale, Baldwin, Mul-T-Lock, or any other make, we can help.
Signs You Need a Pro Right Now
- Your key turns but the deadbolt won’t throw. That usually means the strike plate is misaligned or the bolt is dragging on the frame. Left alone, the lock will fail completely, and it will fail at the worst possible time.
- You have a new roommate, tenant, or ex with a key. Anyone who’s ever held a key to your home is a key holder until you rekey. A rekey is cheap compared to the alternative.
- Your key got lost or stolen. If there’s any chance the key left with identifying information attached, treat it as a security incident, not an inconvenience. Rekey now, not later.
- The lock works with one key but not the spare. That’s a sign the cylinder is worn or the spare was poorly cut. A technician can decode the cylinder and cut fresh keys by code, saving you from an emergency lockout.
- You moved into a new home. You have no idea how many copies of the old key are floating around with contractors, previous owners, or their relatives. Rekeying takes minutes and resets the entire key system to zero.
Our Process, Step by Step
- 1
You call and get a live person. A Preston Locksmith & Security dispatcher answers, takes your address and a description of the problem, and asks for photos of the lock if you can send them. The written price quote is confirmed by phone before any technician is sent.
- 2
You get a trackable arrival time. The Relay Visibility Guarantee means you see the technician’s live arrival window and can follow it the way you’d follow a rideshare. No four-hour sit-and-wait, no “between noon and five.”
- 3
The technician inspects and documents. A background-checked, uniformed tech arrives and photographs the lock, door, and strike plate before touching anything. They confirm the quoted price matches the actual work and get your approval for any change in scope.
- 4
The work is done and photographed. Rekeying, replacement, or repair is completed, tested through multiple cycles, and photographed after the fact so you can see exactly what was done. The written guarantee is stamped on the repair.
- 5
You get a digital invoice with a pay link. The invoice matches the written quote, includes the before-and-after photos, and carries the 365-Day Done Right Promise. If anything fails within a year, the second visit is free, no argument.
How Much Does Residential Locksmith Cost?
A typical residential locksmith visit runs $75 to $180 for a lockout, $120 to $260 for a deadbolt installation, $25 to $40 per cylinder for rekeying, and $8 to $30 for key copies. A smart lock installation runs $150 to $350 including labor and testing. These are honest middle-of-the-market prices, and the price you’re quoted by phone is the price on your invoice. That’s the whole promise, and it’s written, not implied.
What affects the price: the number of cylinders being rekeyed, whether the door needs additional prep or strike plate reinforcement, the lock brand and whether parts need ordering, and whether the job is a scheduled appointment or a 24/7 emergency response. The single best way to avoid overpaying is to get the written quote before the technician is dispatched, and to ask whether there is any additional charge on arrival. There isn’t with us. A free estimate is just that, free and no-obligation, and the phone call takes about five minutes.

Frequently Asked Questions About Residential Locksmith
Residential locksmith service covers any lock, key, or door hardware work on a home: lockouts, rekeying, lock installation, key cutting, deadbolt and strike plate installation, and smart lock setup. The work is done on-site by a technician who carries the keys, pins, blanks, and tools to finish most jobs in one visit. Residential work differs from commercial work because the locks are simpler, the stakes are personal, and the schedule is often urgent.
A standard lockout takes 15 to 30 minutes once the technician arrives, and a rekey runs about 15 minutes per lock. A deadbolt installation with fresh prep and strike plate reinforcement runs 45 to 90 minutes. A smart lock installation, including pairing and testing, usually takes 60 to 90 minutes. You’ll see the live arrival time on your phone before the tech knocks.
A lockout runs $75 to $180, a deadbolt installation runs $120 to $260, rekeying runs $25 to $40 per cylinder, key copies run $8 to $30, and a smart lock install runs $150 to $350. Every price is quoted in writing by phone before dispatch and is the price on the invoice. There is no additional charge on arrival, ever. Call (409) 405-4485 for an exact quote on your specific lock.
Yes, we service Yale, Baldwin, Medeco, Mul-T-Lock, Schlage, Kwikset, Sargent, and Abloy hardware. High-security brands like Medeco and Mul-T-Lock require specialized blanks and key cards, which we hold and use regularly. A standard big-box lock is treated with the same level of care as a high-security cylinder, and we stock common repair parts to avoid second visits.
A live person answers our phones 24 hours a day, 7 days a week, and we dispatch for lockouts and urgent lock failures day or night. You get a trackable arrival time and a written price before the technician is sent. Emergency lockout pricing falls in the same $75 to $180 range, with no after-hours surprise fee added on arrival.
Every repair carries the 365-Day Done Right Promise: if it’s not done right, we make it right, and that includes a free second visit if the repair fails within a year. The guarantee is written on the invoice, not implied in a handshake. If a part fails or a key stops working, call us and we’ll send a technician back, no charge and no argument.
Have a photo of the lock and door ready on your phone, and know whether the property is a rental where a landlord or property manager must be informed. For lockouts, have identification ready to verify you’re authorized to enter. For rekeying, gather all the keys you want to keep working so we can confirm them on the spot. Nothing else is required.
