Why Strongbox Lock & Safe Co. of Washington DC Is Lanham’s Preferred Residential Locksmith Company
We’ve served communities throughout Prince George’s County for over 42 years, and Lanham has been part of our route since the early days. Our technicians know the difference between a 1960s Cape Cod near Route 450 and a 1970s split-level off the Capital Beltway corridor, and they carry the specific hardware those homes need.
Our customers in Lanham leave reviews that mention the same things: the technician showed ID at the door, quoted the exact price on the phone, and the invoice matched. That matters here because too many residents have been burned by the $19-ad locksmith scam that floods the DC suburbs. We’re the verifiable alternative. Background-checked, uniformed, and we stand behind every job with our 90-Day Done Right Promise - in writing, no paperwork to file, no arguing if something needs adjustment.
Response time to Lanham averages 30-45 minutes from dispatch. We know the local traffic patterns around the Beltway interchange and the back routes through Glenarden when Annapolis Road backs up. We’ll be there when we say.
Our Residential Locksmith Services in Lanham
Lock Change
Most lock changes in Lanham involve original Kwikset or Schlage B-series hardware installed in the 1960s or 1970s. These locks have survived multiple owners and decades of use, but their tumblers wear unpredictably and their strike plates often loosen in the softwood door frames common to that era. A typical lock change on a standard entry door in Lanham runs $140-$220, including the new hardware and installation. We stock Grade 1 and Grade 2 options from Schlage, Baldwin, and Yale, so you choose the security level that fits your door rather than accepting whatever’s on the truck.

Residential Lockout
Getting locked out of your Lanham home is never convenient, but it’s especially frustrating in January when a seized storm door cylinder won’t turn and you’re standing in freezing rain. Our emergency lockout response to Lanham is available 24/7, including nights, weekends, and holidays. A standard residential lockout in Lanham costs $89-$150 during regular hours and $150-$220 for after-hours or holiday calls. We open the door without drilling whenever possible, and we’ll show you exactly what failed so you can decide whether to repair or replace.

Deadbolt Installation
Lanham’s federal workforce brings home a security awareness that shows up in our dispatch calls. Grade 1 deadbolts and high-security cylinders are disproportionately popular here compared to other PG County communities. A standard deadbolt installation on a solid wood or metal door in Lanham runs $180-$280. For high-security options like Medeco or Mul-T-Lock with restricted keyways, expect $280-$420 installed. We reinforce the strike plate and frame as part of every installation, because a strong deadbolt in a weak frame defeats the purpose.

Lock Rekey
Rekeying is the most common service we perform in Lanham, and for good reason. With homes changing hands every few years in this market, new owners want the old keys to stop working without replacing hardware that still has life in it. A standard rekey on a single lock in Lanham costs $45-$75. For a full home rekey - typical when you’ve just closed on a property in the 20703 or 20706 zip codes - expect $120-$200 for 3-5 locks. The catch: many Lanham doors have mismatched profiles, a Kwikset knob paired with a Schlage deadbolt from a previous owner’s partial upgrade. That complicates rekeying and often pushes the job toward full replacement for true single-key convenience.

Window Lock and Door Reinforcement
Older Lanham homes often have basement windows with original sash locks that no longer catch, or back doors with minimal framing around the lock area. We install secondary window locks and door reinforcement kits starting at $75 per opening. Door reinforcement, including a heavy-duty strike box and longer screws into the framing, runs $120-$180 per door. These upgrades pair well with deadbolt installations for homeowners who want layered security without replacing every component.

Trusted Brands We Service in Lanham
We install and service Medeco, Yale, Baldwin, and Mul-T-Lock, along with Schlage, Kwikset, Abloy, and Sargent. Our trucks carry the most common cylinders, latchsets, and deadbolts for Lanham’s housing stock, which means most jobs finish in one visit. For federal employees and contractors who want restricted-keyway high-security cylinders, we stock Medeco and Mul-T-Lock key blanks and can cut new keys on-site. No waiting for a distributor in Washington DC or DC.
Common Residential Locksmith Problems We See in Lanham Homes
- Worn tumblers in original 1950s-70s locks. The single-cylinder deadbolts and knob locks installed when these homes were built have internal pins that wear, stick, and eventually fail without warning. We get calls every month from Lanham homeowners whose key suddenly won’t turn in a lock that worked fine yesterday.
- Mismatched lock profiles on the same door. Decades of partial upgrades by previous owners leave many Lanham homes with a Kwikset knob and Schlage deadbolt, or vice versa. What looks like a simple rekey becomes a hardware swap to achieve single-key operation.
- Seized storm door cylinders after freeze-thaw cycles. Lanham’s humid summers and hard winter freezes corrode the exterior cylinders on metal storm doors, which are nearly universal on the area’s ranch and split-level homes. December through February brings a predictable spike in these calls.
- Loose strike plates in aging door frames. The softwood frames common to Lanham’s older homes compress and split around strike plates over decades, allowing doors to rattle and locks to misalign. A new lock in a loose frame won’t solve the underlying problem.

FAQs - Residential Locksmith in Lanham
Original locks from the 1950s-70s can often be rekeyed if the internal mechanism isn’t worn beyond tolerance. We inspect the tumblers, springs, and plug condition first. If the lock still operates smoothly but you need new keys, rekeying at $45-$75 per cylinder is the economical choice. When tumblers stick, the plug wobbles, or the latch doesn’t fully retract, replacement with modern Grade 2 hardware is the better long-term investment. Call (844) 314-7347 and we’ll assess yours over the phone or on-site.
We can replace the corroded cylinder with a marine-grade or weather-resistant version that withstands Lanham’s freeze-thaw cycles far better than the original hardware. A storm door cylinder replacement runs $75-$140 installed. For doors exposed to direct weather, we also recommend periodic lubrication with graphite, not oil-based products that attract moisture. The permanent fix is quality hardware matched to local conditions, not repeated service calls.
We recommend ANSI Grade 1 deadbolts for Lanham’s federal and security-cleared households, specifically the Schlage B660P series or Medeco Maxum 11*603. Grade 1 deadbolts withstand 10 strikes of 75 foot-pounds of force, compared to Grade 2’s 5 strikes. For homes with sensitive materials or home offices, we pair Grade 1 deadbolts with high-security cylinders featuring restricted keyways. Installation with frame reinforcement typically runs $280-$380. Call (844) 314-7347 to discuss your specific security requirements.
We recently serviced a 1960s split-level on Lanham’s Good Luck Road where exactly this situation existed. The owner, a federal contractor, wanted a single-key solution with a high-security cylinder. We replaced both with matching Medeco deadbolts and knobs, restoring one-key convenience and upgrading security. Because Kwikset and Schlage use different keyways, rekeying to one key isn’t possible without replacing at least one lock. For true single-key operation with high security, we typically recommend replacing both with matched hardware from one manufacturer. We’ll quote the full cost upfront before any work begins.
At minimum, rekey every lock so old keys no longer work. For a typical Lanham home with 3-4 entry points, a full rekey runs $120-$200 and takes under an hour. We also recommend inspecting the strike plates and door frames, as original hardware in these 50-plus-year-old homes often hides wear that rekeying alone won’t address. If you want the security upgrade that many Lanham federal employees choose, we can quote Grade 1 deadbolts with high-security cylinders as a package. Estimates are free - call (844) 314-7347.
