Fast, Reliable Lock Installation & Rekey Across St. Johns
Lock installation and rekeying in St. Johns typically costs $75-$210 for a standard rekey (per cylinder, most homes need three to five done) and $95-$285 for new deadbolt or handle set installation, including hardware in the entry-grade to mid-range tier. High-security work with Medeco or Mul-T-Lock cylinders runs higher, and smart lock installation lands in the $160-$380 range depending on the lock and wiring. We answer the phone live, 24/7, at (331) 310-8471, and the price you hear on that call is the price on the invoice, in writing, before anyone drives to your home in St. Johns. If you just closed on a production-built home in Nocatee, Durbin Crossing, Beachwalk, or Bartram Ranch, you likely still have builder-grade hardware keyed to a construction master key that dozens of subcontractors carried. That is the first thing we fix.
Key Takeaways: Lock Installation & Rekey in St. Johns
- Builder-key risk is real here. New homes in St. Johns County master-planned communities often remain keyed to construction-phase master keys until a post-closing rekey is done.
- One visit can secure everything. We rekey house, outbuildings, gates, and workshops to a single key in one trip, which matters when the gate is 200 feet from the house.
- Humidity and salt air corrode locks fast. Pin-and-tumbler cylinders less than two years old can already be pitting from coastal moisture. We see it in St. Johns year-round, worse near the Intracoastal.
- Written pricing is the rule, not a perk. Haven Standard Clause 1: the price on the phone is the price on the invoice. No exceptions since 2002.
- Every visit leaves a photo record. Documented images of the lock, the cylinder, and the finished work, delivered to you before we leave the driveway.
Why Novak Lock & Security Is St. Johns’s Preferred Lock Installation & Rekey Company

Daniel Novak founded this company in 2002 on a rule that most locksmiths in Florida would not sign: the dispatcher gives a firm price on the phone, and the technician is contractually prohibited from changing it at the door. That is Haven Standard Clause 1, and it applies to every rekey, every smart lock install, every emergency callout in St. Johns County, from Nocatee to Durbin Crossing to the rural acreage off County Road 210. Homeowners who have been burned by bait-pricing operations tell us the same thing: they called because somewhere on the page, the price was not hidden behind a “call for quote.” We print it. You read it. Then we work.
We are background-checked, uniformed, and we carry factory-authorized credentials on Medeco, Mul-T-Lock, Baldwin, and Schlage. On a typical St. Johns job, our technician arrives within 60-90 minutes for non-emergency scheduled calls, pulls the existing cylinder, and checks two things before doing anything else: what grade the hardware is, and whether the pin condition already shows corrosion from the humidity that sits over this county every summer. That is how a real locksmith works here. Not guesswork, not upselling, not panic.
We also know the neighborhoods. In Nocatee, Willowcove and Greenleaf Village homes built within the same builder phase often share the same key blank across dozens of units. In Durbin Crossing and Bartram Ranch, we see the same handful of Kwikset SmartKey and Schlage B-series cylinders on door after door. That uniformity lets us stock the right pins, springs, and cylinders for St. Johns before we even pull into the development. It also means we can rekey a house, side-load garage, and detached workshop in a single visit without a second trip back to the shop.
Our Lock Installation & Rekey Services in St. Johns
Our Lock Installation & Rekey team handles everything from a single deadbolt swap to a full-house mechanical and electronic rekey across the county. If you live in St. Johns, you probably have more doors than the average homeowner: a front entry, side-load garage service door, back door to the lanai, maybe a shed, a workshop, a gate at the driveway. We key them all alike, in one visit, with a written scope before we start.
Smart Lock Installation in St. Johns
Smart lock installation in St. Johns runs $160-$380, depending on whether you already have a compatible cylinder or need one added. We install Schlage Encode, Yale Assure, and August smart locks regularly in Nocatee and Beachwalk, where homeowners want keypad or app access so kids and pool service techs aren’t carrying loose keys. We also wire them properly, which matters more than you’d think in newer production homes where the door and jamb tolerances are tight and a mis-drilled strike plate will bind a smart deadbolt within a season. Every smart lock install includes a mechanical backup key and a walkthrough of the app before we leave.

Keyless Entry and Keypad Lock Installation in St. Johns
Keypad lock installation in St. Johns typically runs $120-$260 per door, installed. This is the fastest-growing request we get from Durbin Crossing and Bartram Ranch homeowners who want kids to get in from the bus without fumbling for keys, or who rent out a room and want to delete a code instead of rekeying. Keypad locks also solve a real St. Johns problem: summer storms, wet hands, and keys dropped in the pool. No key, no problem. We stock several keypad models on the truck, so the job is done same-day in most cases, and the code programming is done in front of you, not hidden behind a manual you’ll never read.

Biometric Lock Installation in St. Johns
Biometric locks (fingerprint and, increasingly, Bluetooth proximity) run $200-$420 installed in St. Johns. We recommend them for detached workshops, gun rooms, and home offices where you want audit-trail access, not just key control. A fingerprint lock logs who opened the door and when. On acreage properties along Longleaf Pine Parkway or out toward the St. Johns River, that matters because the workshop is far enough from the house that you won’t hear the door open. We install biometric hardware that is weather-rated for Northeast Florida humidity and salt air, and we pull the old cylinder and rekey the mechanical override to match your house key at no extra charge.

Key Duplication in St. Johns
Key duplication seems simple until you realize the clerk at the hardware store in St. Johns is cutting keys on a worn blade and the result doesn’t work on your new deadbolt. We cut keys to factory specs, including high-security blanks from Medeco and Mul-T-Lock that require an authorization card, which most retail counters cannot legally duplicate. Standard key duplication runs $3-$8 per key. High-security duplication runs $15-$50 and requires proof of ownership. We cut them on-site, and if the key is even slightly off, we recut it before you leave. No charge for the second attempt, ever.

Trusted Brands We Service in St. Johns

We are factory-authorized on Medeco, Mul-T-Lock, Baldwin, Yale, and Schlage, and we carry the pins, springs, and cylinders for these brands on every truck that rolls into St. Johns. If you have Baldwin mortise locks on a semi-custom home in Bartram Ranch, we don’t need to order parts from a distributor and return next week. We rekey it same-day. If you want a Medeco high-security cylinder on a gun room door out on a rural property, we install it with keys you control, nobody else, with a documented photo record and a written warranty. The brand should fit the door and the risk, not the salesman’s markup.
Common Lock Installation & Rekey Problems We See in St. Johns Homes
- Builder-grade cylinders still keyed to construction masters. Lennar, DR Horton, and Pulte build entire phases with one shared master key. Every subcontractor who touched your home had it. Rekeying after closing is not optional; it is the single most important step after you get the keys.
- Sticky, hard-to-turn cylinders every summer. Northeast Florida humidity and salt air pitted and corroded brass pins inside pin-and-tumbler cylinders. We pull deadbolts less than two years old out of Nocatee doors and find pitting already forming on the pins. Rekeying with new pins solves it before the key breaks off.
- Deadbolt throws binding from swollen door jambs. St. Johns County’s production homes are wood-framed, and wood swells in the June-September rainy season. The deadbolt no longer lines up with the strike plate. Homeowners force it, shaving pins, making the lock worse. We realign and rekey in one call.
- Outbuildings and gates keyed differently from the house. This is the most common setup on rural and acreage properties in St. Johns. The workshop has one key, the gate has another, the shed has a third. We key every one of them to the same key as your front door in a single service visit.

FAQs - Lock Installation & Rekey in St. Johns
Yes, absolutely. Builders in St. Johns County, including Lennar and DR Horton, often use a shared construction master key across entire phases of a subdivision. Every subcontractor, laborer, and trade crew that worked on your home during build-out had access to that key. The builder hands you a “new” key at closing, but it is often cut on the same blank and keyed to the same cylinder the construction crew used. Rekeying after closing changes the internal pinning so construction keys no longer work. It takes us about 20 minutes per lock and costs $75-$135 for the first cylinder plus $25-$45 per additional. Call (331) 310-8471 to schedule it before you move your furniture in.
Yes. This is one of the most common calls we get from St. Johns homeowners with acreage or detached buildings. We rekey every lock on the property, house doors, side-load garage, workshop door, shed, and gate, to a single key in one visit. If the gate lock is a padlock or a rim cylinder that is rusted from salt air, we swap it for a weather-rated cylinder and key it to match. The entire property can be on one key, and we leave you with a written record of every lock, its key code, and a photo record of the work. Cost runs $220-$340 for a typical property with five to seven locks.
Humidity. St. Johns County’s high year-round moisture and coastal salt air accelerate corrosion inside pin-and-tumbler cylinders. Brass pins start to pit, the springs weaken, and the cylinder binds. Wood-framed production homes also swell in the June-September rainy season, pulling the deadbolt out of alignment with the strike plate. We open the cylinder, clean or replace the pins, re-lubricate with dry graphite, and realign the bolt throw. The fix holds through the next humid summer. Cost for a cylinder service and rekey runs $75-$135 per lock.
Yes, and it is more common than most homeowners in Nocatee want to believe. Within the same builder phase, many homes are keyed identically using the same key blank and the same construction-phase cylinder. We have confirmed this on repeated calls in Willowcove and Greenleaf Village. The builder key from one house can open the neighbor’s lock, and the construction master key can open both. The only fix is to rekey every exterior cylinder to new pinning that does not match any construction key. We do this in one visit, and we will show you the before and after cylinder so you can see the difference.
Rekeying changes the internal pins so the old key no longer works; the lock housing and hardware stay in place. It is faster, costs less, and is usually the right call if the lock itself is still in good shape. You need a replacement when the lock is physically worn, corroded beyond cleaning, or when you want to upgrade to a higher security grade, like moving from a builder-grade Kwikset to an ANSI Grade 1 deadbolt or a Medeco high-security cylinder. In St. Johns, many homeowners rekey after closing and then replace the front door lock a year or two later when the salt and humidity have done enough damage to the housing. We will tell you which one you need and quote both prices in writing before we touch the first screw.
If you have a lock, gate, or outbuilding issue in St. Johns and you want a real answer from a real locksmith, call (331) 310-8471. We answer live, we quote firm prices on the phone, and we do not change the number at your doorstep. Estimates are free, and every visit leaves a documented photo record. Daniel Novak’s name is on the van and on the invoice because that is the whole argument.
