Why Strongbox Lock & Safe Co. of Washington DC Is Chevy Chase’s Preferred Lock Installation & Rekey Company
Chevy Chase is not a market for generic lock swaps. The concentration of original mortise hardware from the 1900s-1940s, combined with a security-conscious resident base of federal officials and attorneys, means the locksmith who shows up needs two skill sets most competitors lack: restoration craftsmanship and high-security modern integration. We’ve built both over four decades.
Our Lock Installation & Rekey team responds to Chevy Chase calls from our Washington DC base, typically arriving within 45-90 minutes for emergencies. Homeowners in the 20815 and 20825 ZIP codes know our technicians by the uniform, the ID badge presented at the door, and the written quote signed before work begins. The 90-Day Done Right Promise backs every job - if it is not right, we come back, no paperwork, no arguing.
We have rekeyed original Corbin and Russwin mortise locks for families who have owned the same Connecticut Avenue home for fifty years. We have retrofitted Yale and Baldwin smart locks into 1920s foursquares without drilling new holes through century-old oak. That specificity is why Chevy Chase calls us back.
Our Lock Installation & Rekey Services in Chevy Chase
Smart Lock Installation
Chevy Chase homeowners want keyless convenience without sacrificing the character of a period entryway. We install Yale and Baldwin smart locks engineered for thick, solid-wood doors with non-standard backsets - the kind found in pre-1955 Chevy Chase construction. Our technicians map the existing mortise prep, select a retrofit smart lock that seats cleanly within the original escutcheon footprint, and program integration with your home automation system. No visible adapter plates. No holes where they do not belong.
Keyless Entry & Keypad Lock Systems
For the side doors and carriage-house entries common in the larger Chevy Chase lots near Meadowbrook Park, keypad locks eliminate the key-carry problem without the connectivity complexity of full smart-home integration. We install Sargent and Schlage keypad deadbolts rated for exterior exposure, then rekey your remaining keyed cylinders to a single master key for staff or family access. The price we quote on the phone is the price on the invoice.
Biometric Lock & Electronic Lock Installation
Home offices, wine cellars, and gun rooms in Chevy Chase’s larger residences increasingly call for fingerprint or code-based access control. We install Mul-T-Lock and Abloy electronic cylinders that mount into existing mortise bodies - preserving the antique brass thumb latch visible from the hallway while securing the room with biometric-grade verification. This is specialized work. Most locksmiths will sell you a surface-mounted box that looks like an afterthought. We fit the technology inside the architecture.
Key Duplication - Including Antique Keyways
Here is where Chevy Chase truly diverges from neighboring markets. Our shop stocks blanks for Corbin, Russwin, and early Sargent keyways - the skeleton-key and bit-key profiles original to 1910s-1920s mortise locks. On a Colonial Revival home near Connecticut Avenue, we rekeyed the original 1920s Corbin mortise lock without replacing the cast-brass hardware, cutting new keys to the vintage keyway and adjusting the strike plate for seasonal frame shift. If your home still turns with a skeleton key, we can cut spares. Most suburban locksmiths cannot.

Trusted Brands We Service in Chevy Chase
We stock and install Yale, Baldwin, Mul-T-Lock, and Sargent hardware from our Washington DC inventory, with same-day availability for most Chevy Chase service calls. Yale’s smart-lock retrofit lines and Baldwin’s solid-brass mortise collections are particularly suited to the thick door stiles and period escutcheons common in 20815. Mul-T-Lock’s high-security cylinders integrate into antique mortise bodies for homeowners who need modern pick resistance without visible change. We do not install what is on the truck. We install what your door requires.
Common Lock Installation & Rekey Problems We See in Chevy Chase Homes
- Modern cylindrical locksets forced into 1920s mortise doors. The large bore hole and thin faceplate of a standard deadbolt leave exposed wood and weaken the thick stile that was designed for a full mortise body. We see this on rushed jobs from out-of-town handymen. The right fix is either a mortise-format smart lock or a properly sleeved cylindrical conversion - never a hole saw run through century-old oak.
- Deadbolt binding after freeze-thaw cycles. The DC metro’s humid subtropical climate, with cold snaps that can drop below 20°F and then rebound within days, causes repeated freeze-thaw cycles that seize deadbolt mechanisms and warp the solid-wood door frames common in Chevy Chase’s older housing stock, generating a predictable surge in emergency lockout and lock-alignment calls each January-February. We adjust strike plates and lubricate mechanisms with temperature-stable compounds as part of seasonal service.
- Smart locks mounted on narrow period escutcheons. Many Bluetooth deadbolts require a 2¾-inch diameter mounting surface. The cast-brass escutcheons on a 1915 mortise lock may be 1½ inches wide. Forcing the install cracks the plate or splinters the door face. We measure first, then specify a lock that fits - or machine a custom adapter that preserves the original profile.
- Lost skeleton keys with no duplicates. On the streets closest to the DC line, particularly in the denser blocks near Connecticut Avenue, a locksmith will routinely encounter functioning skeleton-key mortise locks original to 1910s-1920s construction; residents frequently call asking for new keys cut to those antique keyways or for the locks to be rekeyed without losing the period hardware, a request almost unheard of in neighboring Bethesda’s postwar subdivisions. We maintain the keyway inventory and the hand-filing skill to answer those calls.

FAQs - Lock Installation & Rekey in Chevy Chase
Yes. We rekey the cylinder inside the existing mortise body, preserving your cast-brass escutcheons, thumb latch, and faceplate. On a recent call near Connecticut Avenue, we rekeyed a 1920s Corbin this way and cut new keys to the vintage keyway. Call (844) 314-7347 to schedule - estimates are free.
Yes, it is common. The solid-wood door frames in Chevy Chase’s 1905-1955 housing stock expand and contract significantly with the DC metro’s temperature swings, causing bolt misalignment by late January most years. We adjust the strike plate and lubricate with temperature-stable compound as part of our $89 Seasonal Tune-Up. Call before the first hard freeze.
Yale’s Assure Lock SL with mortise retrofit kit and Baldwin’s Estate smart handleset line both accommodate the thick stiles and non-standard backsets common in pre-1955 Chevy Chase construction. We measure your door prep on site, then specify the model that fits without new holes. Not every smart lock works in these doors - we will tell you honestly if yours is not a candidate.
Yes, if it is a Corbin, Russwin, or early Sargent keyway. We stock the blanks and cut by hand or code machine depending on the bit pattern. This is a rare service - most locksmiths in the Bethesda market do not carry these blanks. Bring your existing key or the lock itself to verify the keyway profile. Call (844) 314-7347 first to confirm we have your blank in stock.
We never drill new holes through period wood without written authorization. Our first step is mapping the existing mortise prep to identify a keyless lock that seats within the current escutcheon footprint. When that is not possible, we machine a custom adapter plate from brass or stainless that matches the original finish. The door’s character stays intact. The technology disappears inside it.
