Washington’s residential core is unlike anywhere else we work. The city is built from late-19th to early-20th century brick rowhouses with original mortise locksets, tight alley-loaded entries, and a Historic Preservation Office that watches exterior hardware changes with real enforcement power. We’ve been navigating these constraints for over 42 years. We know which blocks require preservation-compliant parts, how humidity swells a 100-year-old door frame against its deadbolt, and why a federal employee moving from a contractor office to a home in Bloomingdale still expects Grade 1 high-security hardware as baseline. That combination - historic fabric, government-grade security standards, and dense urban access - is the everyday reality of our Lock Installation & Rekey work in this city.
Why Strongbox Lock & Safe Co. Is Washington’s Preferred Lock Installation & Rekey Company
We’ve built our reputation in Washington one rowhouse at a time. Homeowners in Columbia Heights and Bloomingdale call us back because we quote a flat price on the phone before the truck rolls, and that price matches the invoice exactly. No bait, no switch, no “service fee” that doubles on arrival.
Our 90-Day Done Right Promise applies to every job in the District, backed in writing with no extra paperwork. If something isn’t right, we come back. Gil Navarro established that standard when he founded the company, and we haven’t wavered in over four decades.
Response time matters in a city where alley-loaded garages and restricted parking can delay less experienced crews. Our technicians carry Washington-specific hardware inventory - preservation-compliant mortise replacements, Medeco and Yale high-security cylinders, and smart lock kits sized for narrow rowhouse door stiles - so most jobs finish in a single visit. Background-checked, uniformed, and ID-presenting at every door, because the person who opens your locks should be the most verifiable person you’ve ever hired.
Our Lock Installation & Rekey Services in Washington
Smart Lock Installation
Smart lock installation in Washington runs $280-$520 installed, depending on whether we’re retrofitting a standard bored lock or integrating with an existing mortise case. Capitol Hill and Shaw rowhouses present a specific challenge: many smart locks require a 2-3/8″ backset and minimum door thickness that original 1920s doors don’t always provide. We carry slim-profile Schlage Encode and Yale Assure models engineered for these tight clearances, and we verify Historic Preservation Office compliance before drilling any new holes in contributing structures. For federal employees and contractors in the District, we also configure smart locks with audit-trail logging and Bluetooth key management that meets their security-clearance protocols.
Keyless Entry
Keyless entry systems in Washington homes and small offices typically cost $220-$480 installed. We install these frequently for embassy staff and diplomatic residences near Massachusetts Avenue NW, where key distribution to household staff and security details demands flexible credential management. Our keyless entry installs include mechanical push-button models for properties where electronic failure isn’t acceptable, and electronic keypad systems with weatherized components rated for DC’s humidity and freeze-thaw exposure. We recently retrofitted a Medeco high-security cylinder inside the antique case of a 1920s rowhouse on 8th Street SE in Capitol Hill whose original Corbin mortise lock had seized in DC’s humid summer - preserving the historic facade while giving the owner a Grade 1 security upgrade that meets GSA-schedule standards.
Keypad Lock
Keypad lock installation in Washington ranges from $180-$390 for residential-grade units, $340-$580 for commercial-grade with audit capability. Rowhouse doors with narrow stiles - common in LeDroit Park and Bloomingdale - often require us to source keypad deadbolts with reduced footprint or to build custom strike-box reinforcements. We stock Kwikset SmartKey and Schlage keypad models with finishes that match period hardware, critical when the Historic Preservation Office restricts visible exterior changes. For rental properties near Embassy Row and throughout Dupont Circle, we program master codes and tenant codes with expiration dates, then rekey the override cylinder on turnover.
Biometric Lock
Biometric lock installation in Washington starts at $420 for residential fingerprint deadbolts, with commercial multi-factor systems reaching $890-$1,400. We recommend these sparingly for historic-district properties due to size constraints, but they see steady demand in modernized Capitol Hill basements, Foggy Bottom condos, and contractor home offices where security-clearance holders store controlled documents. Our biometric installs include enrollment of up to 100 fingerprints, backup mechanical key override, and firmware updates that we perform on-site. DC’s humidity can affect cheaper optical sensors; we specify capacitive or ultrasonic models that maintain accuracy through summer swells.
Electronic Lock
Electronic lock installation and service in Washington covers everything from basic motorized deadbolts to full access-control integration, with typical residential projects at $260-$550. We service and install electronic locks for small embassies, NGO offices, and federal-adjacent consulting firms throughout the District, where credential management and audit logging are standard requirements. Our electronic lock work includes hardwired power with battery backup, WiFi and Z-Wave integration, and coordination with building management systems common in DC’s mixed-use rowhouse conversions. When an electronic lock fails in a 100-year-old door, we diagnose whether the problem is the mechanism, the frame swelling, or the strike plate shifted by another freeze-thaw cycle - and we fix the root cause, not just the symptom.
Key Duplication
Key duplication in Washington runs $4-$18 per key for standard residential blanks, $28-$65 for high-security restricted keys including Medeco and Mul-T-Lock. We duplicate on-site for most residential and commercial keys, with same-day service for restricted keyways where we hold authorized dealer status. Federal employees and contractors often need duplicates of GSA-schedule-compliant keys; we maintain the necessary key blanks and authorization documentation to produce these without the multi-week wait of mail-order services. For historic rowhouse owners with original Corbin or Sargent keyways, we source blanks from specialty suppliers or fabricate from code when the original is too worn to trace.

Trusted Brands We Service in Washington
We install and service Schlage, Yale, and Kwikset daily in Washington, with Medeco and Mul-T-Lock high-security cylinders stocked for government and embassy-adjacent clients. Our trucks carry the full range of finishes - oil-rubbed bronze, antique brass, satin nickel - that match period hardware in historic districts, and we maintain relationships with specialty suppliers for obsolete Corbin and Sargent mortise parts that big-box stores stopped carrying decades ago. Most standard jobs finish with hardware in hand; rare or preservation-specific parts arrive within 24 hours. That inventory discipline means fewer return visits, less waiting, and locks that actually work with your door rather than against it.
Common Lock Installation & Rekey Problems We See in Washington Homes
- Binding deadbolt throws from summer humidity. DC’s humid subtropical climate swells wood door frames in 100-year-old rowhouses, jamming deadbolts that operated smoothly in March. We see this repeatedly in Shaw and LeDroit Park, and we fix it by adjusting strike placement, easing the bore, or specifying humidity-tolerant hardware - not just forcing the mechanism.
- Strike-plate misalignment after freeze-thaw cycles. Washington’s 15-20 annual freeze-thaw cycles shift brick and frame subtly but persistently. Alley-load townhome doors in Columbia Heights and Bloomingdale develop chronic latch and deadbolt misalignment that cheap fixes won’t solve. We relocate strikes with proper clearance and use longer screws that bite into structural framing, not just trim.
- Code violations from non-compliant hardware in historic districts. The Historic Preservation Office actively restricts exterior hardware changes on contributing structures in Capitol Hill, Shaw, and LeDroit Park. We’ve been called to correct DIY or cut-rate installs that used modern cylindrical deadbolts on period doors, requiring full removal and replacement with preservation-compliant mortise hardware - at double the original cost.
- Obsolete keyways in functional antique locks. On blocks near Embassy Row and throughout Capitol Hill, we regularly encounter diplomatic residences and federal-adjacent row houses with 1920s-1940s Corbin or Sargent mortise locks that still function but use keyways no locksmith can duplicate. Our solution: retrofit a high-security cylinder inside the antique case, preserving the exterior appearance while delivering modern key control and pick resistance.

FAQs - Lock Installation & Rekey in Washington
Yes, in most cases, provided the smart lock fits within the existing door prep and doesn’t require new exterior holes or visible modern hardware that alters the historic character. We specify slim-profile models like the Schlage Encode Plus or Yale Assure Lock SL that work with narrow stiles, and we verify HPO compliance before installation. Call (877) 664-8139 - we’ll review your specific block and door condition at no charge.
DC’s humid subtropical climate swells the wood door frame against the deadbolt throw, a pattern we see repeatedly on the same addresses year after year. The fix is rarely the lock itself; we adjust strike-plate position, check frame squareness, and sometimes specify all-weather deadbolts with longer throws designed for seasonal movement. Call (877) 664-8139 and we’ll diagnose whether it’s humidity, frame settlement, or hardware mismatch - estimates are free.
Federal employees and contractors with security clearances most often request Medeco, Mul-T-Lock, or ASSA Abloy cylinders that meet GSA-schedule standards for pick resistance, key control, and drill resistance. These aren’t marketing labels; they’re verified specifications that certain government roles expect at home as well as at work. We stock and install all three, with authorized key duplication on-site. Call (877) 664-8139 to verify your specific clearance requirements.
Yes, we rekey residential and small commercial rental properties throughout Dupont Circle, Kalorama, and the Embassy Row corridor, typically same-day with master-key systems available for multi-unit buildings. We also program keypad and keyless entry systems with tenant-specific codes that expire on lease termination. For property managers, we maintain keyed-alike suites and rekey on tenant turnover without replacing hardware. Call (877) 664-8139 to schedule - we quote flat prices for multi-unit work.
We carry compact drill rigs, right-angle drivers, and hardware sized for Washington’s narrow alley-loaded entries where a standard truck and full toolkit won’t fit.

We’ve worked alleys throughout Capitol Hill, Shaw, and LeDroit Park where other crews simply won’t attempt access. Call (877) 664-8139 - we’ll confirm your alley dimensions and quote a flat price before we roll.
