We’ve been serving Saint Augustine homeowners for over 42 years, from the colonial-era masonry of the Old City to the new master-planned subdivisions in World Golf Village. Saint Augustine isn’t a generic Florida market. The same lock that works on a pre-drilled steel door in Silverleaf won’t fit a Flagler-era Victorian in Lincolnville without custom prep. That’s why our Lock Installation & Rekey team carries both modern smart-lock kits and period-appropriate mortise hardware on every truck.
We answer calls live, 24/7. No voicemail trees. The person who picks up can tell you whether your job needs historic board approval, marine-grade stainless for coastal exposure, or a standard residential deadbolt. And the price you hear is the price on the invoice.
Why Strongbox Lock & Safe Co. Is Saint Augustine’s Preferred Lock Installation & Rekey Company
Saint Augustine residents know the difference between a locksmith who shows up with a drill and one who shows up with a plan. We’ve built our reputation here by doing the job once, doing it right, and backing it in writing.
Our 90-Day Done Right Promise means no arguments, no extra paperwork. If something isn’t right, we come back. Period. Gil Navarro, who leads Strongbox Lock & Safe Co., set that standard decades ago, and we still honor it on every call in Saint Augustine.
Our technicians are background-checked, uniformed, and present ID at the door. That’s not marketing. It’s the minimum standard for people who open your locks. We’ve heard too many stories from Saint Augustine homeowners about the $19-ad scam - a low quote on the phone, a demand for hundreds at the door, and a technician who won’t leave until you pay. We quote flat prices upfront. The number we give you is the number you pay.
We know Saint Augustine’s streets. We know which homes in 32084 need Historic Preservation Board compliance, which properties on Anastasia Island need marine-grade hardware, and which new construction in 32092 takes standard residential prep. That local knowledge saves you time, money, and callbacks.
Our Lock Installation & Rekey Services in Saint Augustine
Smart Lock Installation
Smart lock installation in Saint Augustine typically runs $180-$340 for standard residential doors, $280-$480 for historic doors requiring custom prep or hidden routing. In Saint Augustine’s historic district, smart-lock retrofits are among our most requested jobs - but they’re rarely straightforward. The City’s Historic Preservation Board restricts visible exterior hardware changes on designated structures, which means we often route smart hardware to rear or interior doors while installing period-appropriate dummy hardware on the street-facing facade. We recently worked on a carriage-house door in the Lincolnville neighborhood (32084) that had a seized antique mortise lock from the 1890s. The owner wanted a smart-lock retrofit, but the facade couldn’t be altered per historic guidelines, so we installed a Yale keypad on the interior side door and restored the original cast-iron hardware for street-facing use. We also replaced the swollen wood frame with a marine-grade stainless strike plate to handle the humidity.
Electronic Lock Installation
Electronic lock installation in Saint Augustine costs $150-$320 for residential grade, $320-$580 for commercial grade with audit-trail capability. For beach houses on Anastasia Island (32080), we specify marine-grade stainless or specially coated electronic components. Standard electronic locks fail fast there. Salt-laden air corrodes pins, springs, and circuit contacts within months. We’ve replaced too many “water-resistant” units that weren’t built for actual coastal exposure. Our electronic lock installations in Saint Augustine include hardware rated for the specific environment - not just what’s on the truck.
Keypad Lock Installation
Keypad lock installation in Saint Augustine ranges $140-$280 for residential, with commercial-grade keypads running $220-$420. Keypad locks work well for Saint Augustine’s vacation rental market - owners near the Castillo de San Marcos or along St. George Street need to manage guest access without rekeying between every stay. We install Schlage and Yale keypad units with master-code override, and we can integrate them with property-management systems. For historic district properties, we assess whether the keypad can go on a secondary door or if we need a concealed mounting solution that preserves the facade.
Biometric Lock Installation
Biometric lock installation in Saint Augustine starts at $280 and runs to $520 for residential fingerprint readers with backup key override. Biometric units demand precise door prep and stable mounting surfaces - something we verify before quoting. In Saint Augustine’s older homes, wood frame swelling from humidity can shift biometric sensors out of alignment. We address that during installation, not after the third service call.
Key Duplication
Key duplication in Saint Augustine costs $4-$12 for standard residential keys, $18-$35 for high-security restricted keys from Medeco or Mul-T-Lock. We duplicate keys for the full range of brands we service: Schlage, Kwikset, Medeco, Yale, and others. For historic mortise locks with non-standard keyways, we maintain relationships with specialty key blank suppliers - not every locksmith in Saint Augustine stocks blanks for 1890s-era hardware. We do.
Rekeying Services
Rekeying in Saint Augustine runs $89-$150 for standard residential locks, $120-$220 for high-security cylinders, and $180-$340 for full mortise lock rekeying with custom keyway matching. Rekeying is the right choice when you’ve bought a home, lost a key, or had a tenant turnover. It’s faster than full replacement and costs roughly half. We rekey locks so the old keys no longer operate them - done in one visit, with new keys in your hand before we leave.

Common Lock Installation & Rekey Problems We See in Saint Augustine Homes
- Historic door prep mismatches in 32084. Standard modern deadbolts require a 2-1/8″ bore and 1″ crossbore. Many Flagler-era and colonial homes in Saint Augustine’s historic core have mortise pockets, non-standard spacing, or door stiles too narrow for modern hardware. Installing without assessment risks splitting the door or violating historic board rules.
- Salt corrosion on Anastasia Island (32080). The Atlantic exposure in ZIP 32080 destroys standard lock internals. Pins seize. Springs fail. Keyways pit. We’ve replaced cylinders that jammed solid after two years of coastal air. Marine-grade stainless or specially coated hardware is essential there, not optional.
- Seasonal wood frame swelling in Lincolnville and the Old City. Saint Augustine’s year-round humidity causes wood door frames to expand and contract. Locks that worked fine in March bind by August. We address this with adjustable strikes, weatherstrip coordination, and hardware clearances designed for the local climate.
- Vacation rental turnover without rekeying. The explosion of short-term rentals in Saint Augustine’s walkable historic district means keys change hands constantly. Owners who don’t rekey between management companies or high-turnover guests risk unauthorized access. We rekey fast and provide master-key systems for properties with multiple units.

FAQs - Lock Installation & Rekey in Saint Augustine
Usually not on the street-facing door without Historic Preservation Board approval. Most historic district properties in 32084 must maintain period-appropriate exterior hardware. We typically install keypad locks on rear or interior doors and use matching dummy hardware on the facade. Call (877) 664-8139 and we’ll assess your specific property - estimates are free.
Saint Augustine’s humidity causes wood door frames to swell seasonally, and Lincolnville’s 1880s-1920s wood-frame homes have settled over decades, shifting lock alignment. The combination means strikes and latches that barely engaged in dry weather bind tight in summer. We fix this with adjustable strikes, frame reinforcement, and hardware selected for clearance tolerances that account for seasonal movement.
Schlage and Yale both offer marine-grade or specially coated lines that resist salt corrosion, but the specific model matters more than the brand. Standard residential grades fail within months in 32080’s salt air. We specify stainless steel or specially coated internals, and we avoid hardware with exposed ferrous components. The right specification for your door type and exposure direction determines what we recommend. Call (877) 664-8139 for a site-specific assessment.
If your property is in the Saint Augustine Historic Preservation District (primarily 32084), visible exterior hardware changes typically require board approval. Even “like-for-like” modifications can trigger review. Properties outside the historic overlay in 32086, 32092, or 32095 generally do not need permits for standard residential lock replacement. We identify your property’s status during our estimate and can advise on compliant hardware choices. Call (877) 664-8139 - we’ll check it for you.
Yes, and you should. Vacation rentals in Saint Augustine’s historic district change management frequently, and previous guests, cleaners, and contractors may still have keys.

Rekeying costs $89-$220 depending on lock type - call (877) 664-8139 for an exact quote.
