Why Strongbox Lock & Safe Co. of Washington DC Is Largo’s Preferred Lock Installation & Rekey Company
We’ve worked in Largo long enough to remember when Perrywood and Kettering were new construction. That history matters because the builder-grade Kwikset locks installed in those 1970s and 1980s townhomes are now hitting end-of-life all at once, and we know the failure patterns before we open the truck door.
Our technicians are background-checked, uniformed, and carry company ID. We present it at every door in Largo, whether it’s a single rekey on a rental turnover or a 40-unit HOA job on a shared mailbox cluster. The price we quote on the phone is the price on the invoice. No bait, no switch, no “trip charge” surprises.
Every job carries our 90-Day Done Right Promise, backed in writing. If something isn’t right, we come back. No paperwork to file, no argument to have. We’ve been in this area for over 42 years, and we plan to be here when your grandchildren need locks changed.

Our Lock Installation & Rekey Services in Largo
Smart Lock Installation
Smart locks in Largo townhomes present a specific challenge: many HOAs prohibit visible keypads or exterior hardware modifications that alter the uniform appearance of rowhouse fronts. We install discreet interior-mounted smart deadbolts and retrofit solutions that keep the exterior looking original while giving you app control, temporary access codes for visiting family, and auto-lock scheduling. For the wood doors common in 1970s Largo construction, we reinforce strike plates and adjust for seasonal frame swelling so the smart mechanism doesn’t bind when humidity peaks in July and August.
Keyless Entry
Keyless entry systems are popular with Largo’s federal and defense-contractor renters who rotate through short-term assignments. We install keypad and touch-activated systems that eliminate lockout risk without requiring smartphone pairing, which matters for households with older members who aren’t carrying devices. In communities like Kettering, where shared walls mean sound travels, we specify quiet motorized deadbolts that won’t wake neighbors at 6 AM. Our keyless installations include rekeying of any existing deadbolts you want to keep as backup.
Keypad Lock Installation
Keypad locks bridge the gap between traditional hardware and full smart home integration. For Largo’s garden apartment complexes and townhome rentals, we install commercial-grade keypad locks with audit trail capability, so property managers know who entered and when. We stock Baldwin and Yale keypad hardware with weather sealing rated for Prince George’s County’s freeze-thaw cycles. The keypads we specify for Largo’s exposed entries use rubberized membrane buttons that resist moisture infiltration, unlike the cheap units that fail after one humid summer.
Biometric Lock Installation
Biometric fingerprint locks are increasingly requested by Largo homeowners upgrading from failed builder-grade hardware. We install Mul-T-Lock and Sargent biometric systems with capacitive sensors that read through minor moisture, which matters in Largo’s humid climate. These installs require precise door prep on the hollow-core and lightweight solid-core doors common in 1970s-1990s townhomes. We reinforce the door structure and upgrade strikes to prevent the frame flex that throws off biometric alignment. Every biometric install includes mechanical key override and a walkthrough on fingerprint enrollment.
Key Duplication
We cut keys on-site for Largo customers, including high-security Medeco and Mul-T-Lock blanks that require specialized keyways. For HOA master key systems and shared mailbox clusters, we duplicate restricted keys only with proper authorization and documentation. Our mobile units carry the full range of residential and commercial key blanks, so most Largo customers walk away with working copies in under ten minutes.

Trusted Brands We Service in Largo
We install and service Yale, Baldwin, Mul-T-Lock, and Sargent hardware in Largo, with parts stocked locally for same-day repair and replacement. These aren’t brands we special-order from a warehouse three states away. We carry them on the truck because we’ve learned which models hold up to Largo’s humidity and which don’t. For the aging Kwikset hardware failing across Largo’s 1970s-1990s housing stock, we can upgrade to bump-proof, pick-resistant cylinders from Medeco or Mul-T-Lock without replacing the entire lock body, saving the cost of new hardware when the mechanism still has years left.
Common Lock Installation & Rekey Problems We See in Largo Homes
- Seasonal deadbolt binding from door-frame swelling. Largo’s humid mid-Atlantic summers cause wood door frames to expand, misaligning strikes and preventing deadbolt throw. We see this repeatedly in the older wood-framed townhomes near Kettering and Perrywood, where original construction tolerances were tight to begin with.
- Corroded builder-grade Kwikset cylinders. The original Kwikset hardware installed during Prince George’s County’s suburban boom is now decades old. Freeze-thaw cycles crack cast zinc bodies, and humid summers corrode internal springs. We’ve replaced hundreds of these in Largo, often upgrading to Schlage or Medeco while we’re there.
- Seized sliding patio door locks. The 1970s-1980s townhome units throughout Largo commonly have sliding glass doors on rear alley or patio entries. Winter freeze-thaw cycles crack or seize the original mortise locks, and replacement parts are often discontinued. We retrofit modern locking solutions that match the original mounting points.
- HOA lock-type restrictions limiting upgrade options. Many Largo HOAs prohibit visible exterior hardware changes, including keypads, smart locks with visible components, or non-matching finishes. We navigate these restrictions by installing interior-mounted smart mechanisms and hardware that maintains the community’s uniform appearance.

FAQs - Lock Installation & Rekey in Largo
Many Largo HOAs restrict visible exterior hardware changes, including non-matching finishes, exposed keypads, or smart locks with visible components. We solve this by installing interior-mounted smart mechanisms and selecting hardware finishes that match community standards. Before any install, we review your HOA’s published guidelines or contact the management company directly. Call (844) 314-7347 and we’ll verify compatibility with your specific community’s rules.
Largo’s humid mid-Atlantic climate causes wood door frames to swell in summer, misaligning the strike plate and binding the deadbolt throw. This is especially common in 1970s-1980s townhomes with original wood framing that has absorbed decades of seasonal moisture cycles. We fix this by adjusting strike alignment and often upgrading to adjustable strikes that accommodate seasonal movement. Call (844) 314-7347 for an assessment, estimates are free.
Yes, Medeco and Mul-T-Lock high-security cylinders can retrofit most Kwikset deadbolt bodies, giving you pick-resistant, bump-proof protection without replacing the entire lock. We do this upgrade regularly in Largo’s aging townhome stock. The cylinder swap takes 20-30 minutes and costs $140-$220 per door, including new keys. Call (844) 314-7347 for an exact quote on your specific hardware.
For Largo’s older wood doors, we recommend Yale Assure Lock SL with a reinforced strike package, or a discreet interior-mounted smart deadbolt that doesn’t stress the door with heavy exterior hardware. The key is matching the smart lock’s torque requirements to the door’s structural integrity and accounting for seasonal frame swelling. We assess door condition before recommending a specific model. Call (844) 314-7347 to schedule a no-charge evaluation.
A typical Largo HOA community rekey of 20-40 townhome units takes one to two working days, depending on unit access coordination and whether shared mailbox clusters are included. We recently rekeyed an entire row of townhomes in the Kettering subdivision after the HOA lost the master key for the shared CBU. We swapped out corroded Kwikset deadbolts on aging wood doors that had swelled from humidity, installing new Schlage bump-proof locks with reinforced strikes to stabilize alignment against seasonal frame movement. For volume HOA work, we quote per-unit pricing and schedule around resident availability. Call (844) 314-7347 to discuss timeline and pricing for your community.
