Fast, Reliable Residential Locksmith Across Miami
A residential locksmith in Miami is who you call when your key snaps in the deadbolt on a humid August night, when a new apartment on Brickell comes with old Schlage hardware and no idea who else has a copy, or when a wood-frame door jamb from 1940 finally gives out. We’re Preston Locksmith & Security, and our Residential Locksmith team handles lockouts, rekeys, deadbolt installation, and door reinforcement across Miami every day. You call, get a live person, and receive a written price before anyone is dispatched. That price is the price on the invoice. No call-out surcharge added on arrival. Call (409) 405-4485 and you’ll have a background-checked, uniformed technician headed your way with a live arrival time you can track from your phone.
Why Preston Locksmith & Security Is Miami’s Preferred Residential Locksmith Company
We founded Preston Locksmith & Security in 2008, and every job carries The Relay Visibility Guarantee: a written price before work begins, a live trackable arrival time, before-and-after photos of the work, and a written guarantee on every repair. That guarantee means a free second visit if the repair fails, no charge and no argument. In a city where lockout scams are a documented problem, we put a name and a face on the job before the knock. Kevin Yoon leads our crew, and the technicians we send across Miami are background-checked and arrive in uniform so you know exactly who is at your door.
Serving Miami means understanding what salt air and humidity do to locksets, deadbolts, and wood jambs. We see swelled door frames in Coconut Grove, corroded cylinders in Edgewater, and worn Schlage hardware in Wynwood rentals that have seen three landlords and a dozen tenant changes. Local experience shapes our repair decisions: shim the strike, lubricate the cylinder, or replace the jamb entirely. We stock parts for names like Schlage, Kwikset, and Medeco, so most hardware issues get handled the same visit.
Deadbolt Installation in Miami
Deadbolt Installation in Miami is one of the most common calls we handle, and it’s rarely as simple as a $19 big-box swap. Much of Miami’s housing stock is 1920s to 1950s masonry with wood-frame door jambs that have swelled and shifted in the salt air. A factory-cut replacement deadbolt often won’t hit the strike plate cleanly without a chisel and shim, which directly shapes how long and how much the job actually costs. You’re not paying for the bolt alone. You’re paying for a jamb that closes correctly in a house that has moved.
A standard single-cylinder deadbolt installation on a properly aligned Miami door typically runs $95 to $180, including the hardware. On older masonry homes where the strike plate is recessed or the jamb has shifted, expect $140 to $230 because the work includes routing, shimming, and resetting the plate so the deadbolt latches every time. ANSI Grade 1 deadbolts from Schlage or Medeco run higher on parts but last far longer in humidity.
Jamb and Strike Plate Work
In Little Havana, a homeowner on SW 8th Street was locked out of her 1940 masonry home with an original mortise lock whose cylinder had seized from humidity. Our tech used non-destructive entry on the pin and tumbler mechanism and left the hardware intact. We then rekeyed the existing lock cylinder and installed an ANSI Grade 1 deadbolt on the wood jamb, shimming the strike so it latched cleanly. She got a written quote before we dispatched, and the final bill matched it. That’s the standard on every Miami job.
If your door frame shows splitting around the strike screws or the deadbolt grinds when you lock it, the jamb itself may need reinforcement. We replace the short strike screws with 3-inch screws that anchor into the stud, and add a metal strike box where the original one has worn through.
Locksmith Key Replacement in Miami
Locksmith Key Replacement in Miami covers two very different jobs, and knowing which one you need saves money. If you’ve lost your last key, we can originate a new key from the lock itself, or swap the cylinder and rekey it so the old key no longer works. If you have a working key and just want extra copies, we cut and code Schlage, Kwikset, and Medeco keys on the spot from our mobile setup. No trip to the hardware store that doesn’t carry the right blank.
Key duplication in Miami typically runs $6 to $15 per standard Schlage or Kwikset key. Cutting a new key from a lock with no existing key costs $25 to $60 depending on the cylinder. Full rekeying, where we change the internal pins so old keys no longer turn the lock, runs $18 to $35 per cylinder in Miami, with a written price before we start. That’s the honest range, and the price on your invoice matches it.
Lost Keys and Tenant Turnovers
After a tenant turnover in a Brickell condo or a Hialeah rental, rekeying is the cost-smart move. No new hardware, no door modification, just new internal pins and new keys. The old keys become useless. A full rekey on three locks in a Miami apartment runs $90 to $180, rarely more, and most jobs finish in under ninety minutes.
Trusted Brands We Service in Miami
We train on premium hardware because Miami homes run the full spectrum: Medeco and Abloy high-security cylinders in newer construction, Baldwin and Schlage deadbolts in Coral Gables and Key Biscayne, and plenty of old Kwikset that has survived hurricanes and humidity. We stock common Schlage and Kwikset parts locally so a same-day fix doesn’t turn into a week-long parts wait. With Medeco or Abloy keyways, we verify proof of ownership before cutting or servicing keys, which protects you as much as it protects the lock.
Common Residential Locksmith Problems We See in Miami Homes
- Humidity-seized cylinders: Salt air and 80% humidity corrode brass internals over time. Keys turn hard, then not at all. We clean, lubricate, or replace the cylinder before it snaps in the door.
- Swollen wood jambs: Masonry homes from the 1920s-1950s settle. The strike plate moves, the deadbolt binds, and eventually the latch misses entirely. Shimming and reinforcement fixes the alignment.
- Stripped or missing strike screws: The builder screws are short and pull out of soft wood. We replace them with 3-inch structural screws into the stud, and the door actually locks again.
- Key-control after tenants: Rentals across Edgewater and downtown change hands constantly. Rekeying the existing cylinders is faster and cheaper than replacing good hardware.

FAQs About Residential Locksmith in Miami
Can a locksmith open my Miami home without drilling?
Yes, in most cases. We open the majority of residential locks in Miami with non-destructive picking or bypass methods using pin and tumbler technique, no drilling. If the lock is beyond saving or hardened against picking, we’ll tell you before we drill, and the price for that outcome is agreed in writing before we start. Call (409) 405-4485 and tell us what kind of lock you have.
Do I need a rekey or a full lock replacement for my Miami house?
Rekey if the lock operates fine but you want old keys dead, like after a tenant or roommate leaves. Replace if the cylinder is corroded, the deadbolt grinds, or the jamb is split. Rekeying costs $18 to $35 per cylinder in Miami, while replacement starts at $95. A quick phone description usually tells us which path makes sense.
How do I know the locksmith at my door is who they say they are in Miami?
Your technician will be in uniform, driving a marked vehicle, and you’ll have their name and photo before they arrive. Every Preston Locksmith & Security tech is background-checked, and your written quote includes the tech’s name. No anonymous van, no unmarked arrival, no story. Kevin Yoon himself runs the crew, and the tracking link shows you exactly when the tech pulls up.
What deadbolt should I install on a Miami home with an old wood jamb?
For older masonry homes in Miami, an ANSI Grade 1 deadbolt from Schlage or Medeco with a reinforced strike and 3-inch screws is the right call. The jamb needs to be shimmed and plumb so the bolt throws without binding in humidity. We’ll quote the hardware and the jamb work together, written before we start, so you know the full number.
Will you give me a price before you come out, not just a teaser?
Yes. You get a full written price before dispatch, with the specific lock, parts, and labor listed. That is the invoice price. We don’t quote one number over the phone and add a second on arrival. Call (409) 405-4485 now for a free estimate on any Miami residential lock issue.
