Lock Change & Installation in Jacksonville
Hardware is the part you buy; the installation is the part that keeps working. The Keys Maker changes and installs door hardware across Duval, Clay, St. Johns, Nassau, and Baker counties — deadbolts, knobs and levers, mortise locks, and commercial hardware — fitted square so it lasts in this climate. Fresh installation on a door that never had a lock starts at $140. Call (904) 827-7496 for your number.
If your hardware is healthy and only the key is a problem, rekeying is cheaper and we’ll say so.

Installation Work We Do
Deadbolt installation. On a door that has one, or a fresh bore on a door that doesn’t. A single-cylinder deadbolt with a proper strike into the framing does more for a front door than almost anything else you can buy.
Knob and lever replacement. Including levers for accessibility, which are easier on hands that don’t grip well and are worth doing before they’re needed.
Full hardware upgrades. Builder-grade sets swapped for hardware that will survive the climate. Schlage, Kwikset, Baldwin, and Assa Abloy are the everyday brands here.
Mortise locks. The older Riverside, Avondale, Springfield, and downtown doors run on these, and they are not a big-box part. Repaired, rebuilt, or replaced in kind so the door keeps its character.
Strike plates and reinforcement. The cheapest real security upgrade there is. A three-inch screw into the stud beats a beautiful lock in a soft frame every time.
Door repair around the lock. Chewed-out latch pockets, splintered jambs, holes left by hardware that didn’t line up.
After a break-in. Damaged hardware replaced and the door secured the same visit — see emergency service if it just happened.
Commercial hardware. Panic bars, closers, and grade-rated locks for doors that get used hundreds of times a day. More on the commercial page.
Smart lock installation. Covered separately on our smart lock page.
Installation Is Most of the Security
The frame fails before the lock does.
Almost no forced entry defeats the lock itself. It splits the jamb around it. A long strike plate anchored into the stud behind the frame is a small part and a small labor charge, and it changes the outcome more than upgrading from a good deadbolt to a better one.
Alignment is why locks die young.
A bolt that doesn’t meet its strike square wears itself out, and the owner blames the lock. Getting the geometry right is the difference between hardware that lasts a decade and hardware you replace in three years.
The grade on the box means something.
Residential hardware is graded, and the cheapest tier is built for a builder’s budget, not for a front door in a humid climate. We’ll tell you where spending more actually buys you something and where it just buys a finish.
You keep one key.
New locks get keyed alike to each other, and to the hardware you’re keeping where the keyways allow it. Nobody wants to leave an installation carrying four new keys.
What This Climate Does to Door Hardware
Salt air is the headline. On the barrier islands and anywhere east of the Intracoastal, exterior hardware corrodes on a schedule that surprises people who moved here from anywhere drier. Finishes pit, springs weaken, and cylinders bind. Hardware rated for coastal exposure costs more and lasts long enough to be the cheaper choice.
Humidity moves doors. Wood swells through the summer and shrinks back in January, so a bolt that was perfect in winter grinds in August. A lot of what looks like lock failure here is seasonal movement, and it’s fixable at the strike rather than the cylinder.
Storm season adds pressure. Wind-loaded doors and repeated slamming loosen strikes and hinges, and after every serious blow we see a run of doors that no longer latch cleanly.
And the county’s building boom left a lot of houses in Nocatee, Julington Creek, and along CR 210 wearing the least expensive hardware that met the spec. Those sets are the ones most often worth replacing rather than repairing.
How an Installation Goes
1
Tell us the doors and what’s on them now. How many, interior or exterior, and whether we’re supplying the hardware or fitting yours.
2
You get the price, hardware and labor separated. No mystery bundle. Fresh installations start at $140.
3
Fitted, aligned, keyed alike, tested. Every door opened and locked in front of you, from both sides, before we pack up.
Lock Installation Questions, Answered Straight
Rekey if the hardware is in good shape and the only problem is who holds a key — it’s cheaper and it kills every old key. Change the locks if the hardware is worn, corroded, builder-grade, or simply not enough for the door. We’ll give you the honest read at the door, including when the cheaper answer is the right one.
Fresh installation on a door with no existing lock starts at $140. Swapping hardware into an existing prep costs less. Hardware is priced separately from labor so you can see both. Our rates page has the full list.
Yes. Bring what you bought and we’ll fit it. If it’s the wrong backset, the wrong bore, or hardware that won’t survive this climate, you’ll hear that before we install it rather than after.
Schlage, Kwikset, Baldwin, Assa Abloy, and Ring among others. The right brand depends on the door and how exposed it is — a shaded interior-facing entry and a west-facing door two blocks from the ocean are different problems.
Yes, and you should ask for it. New hardware gets keyed alike as part of the install, and existing locks can usually be brought into the same key if the keyways are compatible.
Often not. That’s usually alignment — a door that has moved with the seasons or hinges that have sagged. Adjusting the strike is a small job and it’s the first thing we check.
Yes. The historic homes in Riverside, Avondale, Springfield, and around downtown are full of them. They can often be rebuilt rather than replaced, which keeps the original hardware on a door where it belongs.
A typical three- or four-door home is a single visit, usually well under two hours. Fresh bores on doors that never had hardware take longer, and so does anything that needs the frame repaired first.
Get New Locks Fitted Properly
Call (904) 827-7496 with your door count. You’ll get hardware and labor priced separately, an honest answer about whether a rekey would do instead, and locks that are aligned to last in this climate.

Frequently Asked Questions
Duval, Clay, St. Johns, Nassau, and Baker counties: Jacksonville and its neighborhoods, Julington Creek, Fruit Cove, Nocatee, Ponte Vedra, the CR 210 corridor, St. Johns, St. Augustine, Yulee, Callahan, Fernandina Beach on Amelia Island, and Macclenny. If you’re near the edge of that map, call — we’ll give you a straight yes or no.
As fast as the nearest van allows, and you’ll get the honest ETA on the phone. Inside northern St. Johns and south Jacksonville, that’s usually quick; we don’t quote fantasy minutes just to win the call.
You describe the job, we quote it, and that quote is the price you pay. If the job turns out bigger than described, work pauses and you approve the new number first. No trip-fee surprises, no upsell at the door.
Yes — The Keys Maker LLC is a licensed and insured Florida business (St. Johns County Business License No. B.L1101834), and every technician is background-checked. Worth knowing: Florida has no statewide locksmith trade license, which is exactly why you should ask any locksmith what stands behind the word. Ours is above — verify it with St. Johns County yourself.
Yes, for most makes and model years — cut and programmed on site from the vehicle itself, including transponder and proximity keys. No tow to a dealer required.
Rekeying keeps good hardware and changes which key works it — the right move after a move-in or lost keys. Replacement is for worn, damaged, or low-grade locks. We’ll tell you which one your door actually needs, and rekeying is usually the cheaper answer.
Yes — supply, install, and configure, or install one you already bought. We’ll also tell you honestly when a smart lock is the wrong fit for a door or a household.
Check the other doors, then call (904) 827-7496. Don’t break a window — the glass usually costs more than the locksmith. You’ll get a price and an ETA on the same call, at 2 PM or 2 AM.
Warning signs: a $19 or $29 phone quote that triples on arrival, an unmarked car, no company name on the phone, cash-only pressure, and drilling as the first suggestion. A real local shop gives a firm quote, shows up marked, and can prove who they are.
After the work is done, at the quoted price. Card or cash both work. You’ll never be asked to pay before you’re back inside.
No — emergencies are the loud half. The quiet half is scheduled work: rekeys, lock upgrades, smart locks, master key systems, and new-home lock changes, booked at your convenience, evenings and weekends included.
Yes. One key for the owner, limited keys for staff, and a plan for what gets rekeyed when someone leaves. We build it around how your business actually runs.
Usually not. The fragment comes out with extraction tools, the lock gets checked, and in most cases you just need a fresh key. Don’t dig at it with tweezers — that’s how a cheap fix becomes a replacement.
Rarely. Non-destructive entry is always the first approach; drilling is the last resort for certain high-security cylinders, and you’ll approve it — and the replacement cost — before it happens.
He’ll confirm he’s from The Keys Maker and the price you were quoted. Ask for the company name before you open up — any honest tech expects the question. If anything feels off, call us back on (904) 827-7496 and we’ll confirm who’s standing there.
Salt air corrodes pins, springs, and finishes from the inside out — beach-side hardware can age a decade in a few summers. A yearly clean and graphite lubrication helps; when a coastal lock starts grinding, replace it before it seizes on a Sunday night.
Tips for Getting the Best Locksmith Service
Get the price on the phone — and treat a refusal to give one as your answer. Photograph your keys while you still have them; a picture speeds up any replacement. Keep one spare outside the house — with a person you trust, not under the mat. Rekey on move-in day, because you never know how many copies the last owner handed out. Save our number before you need it: (904) 827-7496 reads a lot better from inside the house.
