Why Strongbox Lock & Safe Co. Is Lilburn’s Preferred Lock Installation & Rekey Company
Lilburn homeowners know the difference between a locksmith who quotes $19 on the phone and one who tells you the real price upfront. We’re the second kind. Our Lock Installation & Rekey team has built its reputation in Gwinnett County on flat pricing, background-checked technicians who present ID at the door, and a written guarantee that actually gets honored.
Our reviews from Lilburn customers consistently mention two things: we show up when we say we will, and the price on the invoice matches the price on the phone. No add-ons, no “service fees” that materialize after the work is done. We’ve earned that trust one door at a time, from the older subdivisions near Killian Hill Road to the commercial corridors along US-29.
Response time to Lilburn is typically under 45 minutes during business hours and under an hour for evening and weekend calls. We know the local streets - Camp Creek, Newburn Drive, the Lawrenceville Highway corridor - and we don’t waste time getting lost or calling for directions.
What sets us apart in this market is our familiarity with Lilburn’s specific housing stock. The bulk of homes here were built during Gwinnett County’s first suburban boom, 1970 to 1995, and that matters when you’re installing a deadbolt on a door frame that’s settled for forty years. We carry reinforcement plates, longer screws, and the patience to do the job right rather than force hardware that doesn’t fit.
Our Lock Installation & Rekey Services in Lilburn
Smart Lock Installation
Smart locks are popular in Lilburn’s multi-generational households, where adult children want remote access for aging parents and family members coming and going at different hours. We install Schlage Encode, Yale Assure, and Kwikset Halo models that integrate with existing Wi-Fi - no hub required. The challenge in this market is door quality. Many Lilburn homes built in the 1980s have hollow-core exterior doors that can’t support the weight and torque of a smart lock without reinforcement. We assess the door first, quote the full job including any needed reinforcement, and install hardware that will last. No partial solutions that fail six months later.
Keyless Entry
Keyless entry systems eliminate the key entirely - a practical upgrade for Lilburn families who have lost track of how many copies exist after decades of rekeying. We install keypad deadbolts from Schlage and Kwikset that stand up to metro Atlanta’s humidity and temperature swings. For commercial properties along Lawrenceville Highway, we also service electronic access control with audit trails and scheduled user codes. Every installation includes programming walkthrough and a written code record, so you’re never locked out of your own system.
Keypad Lock
Standalone keypad locks remain our most requested upgrade for Lilburn’s older ranch homes. They don’t require smartphone apps or Wi-Fi - just a code you can change yourself. We see heavy demand for these from families in the 30047 zip who want simple, reliable access for children, housekeepers, or visiting relatives without distributing physical keys. Our technicians carry Schlage and Kwikset keypad models in the truck, and most installations finish in under an hour. We also handle the removal of old keypad locks that have failed after years of exposure to Lilburn’s humid summers.
Biometric Lock
Biometric locks - fingerprint readers - are gaining traction in Lilburn’s professional households and home offices. We install models from trusted manufacturers with proven sensor reliability in humid climates. The technology has improved significantly; modern fingerprint readers handle the moisture and temperature variation common in Gwinnett County better than early generations. We recommend biometric locks for interior applications - home offices, gun safes, wine rooms - where the environmental exposure is controlled. For primary exterior doors in Lilburn’s older homes, we typically suggest a hybrid keypad/biometric system with mechanical key override for redundancy.
Electronic Lock
Electronic locks encompass the full spectrum of powered access control, from simple battery-operated deadbolts to hardwired commercial systems. In Lilburn, we install electronic locks for both residential and small commercial clients, particularly along the US-29 corridor where family businesses need reliable access management without enterprise-level complexity. We service what we install, and we keep common replacement parts in stock - motors, battery packs, circuit boards - so a failed electronic lock doesn’t leave you waiting days for a mail-order part.
Key Duplication
Key duplication at Strongbox is done on precision machines with verified key blanks - not the self-service kiosks that produce inconsistent results. For Lilburn customers, we duplicate standard Kwikset and Schlage keys while you wait, and we can generate new keys from lock code numbers when the original is lost. In multi-generational households where key history has become unclear, we often recommend rekeying the lock to a new keyway rather than adding yet another duplicate to an uncertain chain. That conversation happens upfront, with no pressure either way.

Trusted Brands We Service in Lilburn
We install and service Schlage, Kwikset, Medeco, and Yale hardware from stock carried in our service vehicles. For Lilburn’s specific conditions - settled door frames, humid summers, older hollow-core doors - we typically recommend Schlage deadbolts for their solid construction and adjustable backsets, or Kwikset SmartKey cylinders when customers want the flexibility to rekey themselves without disassembling the lock. Medeco high-security cylinders are our go-to for homeowners who want pick-resistant, drill-resistant protection, particularly for side and rear doors that are less visible from the street. We don’t push premium brands where standard hardware will serve; we match the lock to the door, the threat, and the budget.
Common Lock Installation & Rekey Problems We See in Lilburn Homes
- Seasonal deadbolt misalignment on settled ranch homes. Lilburn’s hot, humid summers cause wood door frames in 1970s-1990s homes to swell, throwing deadbolt throws out of alignment with the strike plate. We see this every July and August, and the fix is never just “tighten the screws” - it requires assessing frame plumb, adjusting the strike location, and sometimes installing an adjustable strike plate.
- Hollow-core doors that can’t support smart lock weight. Builder-grade homes in the Parkview High School district often have original hollow-core exterior doors that flex under the torque of a motorized smart lock. We reinforce or replace these doors before installing smart hardware, because a smart lock on a weak door is no security upgrade at all.
- Lost key history in multi-generational households. In Lilburn’s South Asian and Korean communities concentrated along Lawrenceville Highway, single-family homes often house three generations with separate rekeying events stretching back decades. When no master key record exists, a simple rekey isn’t possible - we need to re-pin to an entirely new keyway or replace the hardware entirely.
- Original builder-grade Kwikset hardware failing after 40+ years. The Kwikset knobs and deadbolts installed in Lilburn’s first suburban boom were never designed for four decades of use. Internal springs fatigue, cylinders wear, and the lightweight strike plates provide minimal kick-in resistance. We replace these with modern grade 2 or grade 3 hardware and reinforce the strike mounting with 3-inch screws into the framing stud.

FAQs - Lock Installation & Rekey in Lilburn
Humid summers cause wood door frames in Lilburn’s 1970s-1990s homes to swell seasonally, shifting the strike plate position relative to the deadbolt throw. The fix is proper frame assessment and often an adjustable strike plate installed with long screws into the framing stud, not just the door jamb. Call (877) 664-8139 - we can diagnose this in person and quote the repair flat.
Yes, and this is common in Lilburn’s South Asian and Korean communities along Lawrenceville Highway. When key duplication history is lost across decades of separate rekeying events, we typically re-pin the lock to a completely new keyway or replace the hardware, ensuring no previously distributed key will operate it. We handle this discreetly and explain the options clearly before starting work.
Not without reinforcement or door replacement. Hollow-core doors lack the structural integrity to support a smart lock’s weight and motorized torque long-term. We assess your specific door, quote reinforcement or replacement if needed, and install hardware that will actually last. The total job typically runs $249-$489 depending on door condition and smart lock model chosen.
Very common, and often more complex than a standard rekey. Resale homes in this corridor frequently serve multi-generational families with unclear key history, so buyers often request full hardware replacement for certainty. We also see new homeowners upgrading from original builder-grade Kwikset to Schlage or Medeco during the same visit. Call (877) 664-8139 for a free estimate before closing.
Schlage deadbolts for their solid zinc construction and adjustable backsets that accommodate settled frames, and Kwikset SmartKey when you want self-rekeying capability. For high-security needs, Medeco cylinders resist picking and drilling. We stock all three in our service vehicles and match the specific model to your door condition and security requirements.
