Why Strongbox Lock & Safe Co. Is Gaithersburg’s Preferred Lock Installation & Rekey Company
We’ve been serving communities like Gaithersburg for over 42 years. That longevity matters here, where the mix of 1970s-era townhomes, federal-contractor housing turnover, and HOA-governed communities creates lock problems that inexperienced operators simply haven’t encountered.
Our reputation in Gaithersburg rests on four things our customers tell their neighbors about. First, our 90-Day Done Right Promise - every job backed in writing, no paperwork to file, no arguing if something needs adjustment. Second, our flat-price quoting: the number you hear on the phone is the number on the invoice. Third, our technicians are background-checked, uniformed, and present ID at your door - because the person who opens your locks should be the most verifiable person you’ve ever hired. Fourth, a live person answers every call, including nights, weekends, and holidays.
We know the local landscape. Our Lock Installation & Rekey in Gaithersburg team regularly handles the restricted-keyway requirements that federal contractors and biotech employees along the I-270 corridor need. We also understand the HOA common-area hardware rules that govern Montgomery Village, Kentlands, and Lakelands. That local fluency means faster diagnosis, fewer callbacks, and work that passes inspection the first time.
Response time to Gaithersburg is typically 30-45 minutes during business hours, 45-60 minutes for after-hours emergency calls. We stock Schlage, Kwikset, Medeco, and Abloy cylinders on every truck, along with the electronic access hardware common to condo lobbies and multi-unit buildings around Rio and the Washingtonian Center.
Our Lock Installation & Rekey Services in Gaithersburg
Smart Lock Installation
Smart lock installation in Gaithersburg runs $280-$520, including the device, adapter plates, and Wi-Fi bridge if needed. We install Yale, Schlage Encode, and Kwikset Halo models that integrate with existing deadbolt prep - critical for the 1970s-1990s door stock common in Montgomery Village and Lakelands, where bore holes may need reaming or strike mortises need deepening. We also handle the low-voltage wiring for electronic strikes on common-area doors in Kentlands condos, coordinating with your HOA property manager where required.
Keyless Entry
Keyless entry systems for Gaithersburg homes and small offices range from $180 for a basic keypad deadbolt to $640 for a commercial-grade prox-card system. Federal contractors in the I-270 corridor often need keyless entry that logs access events - we install Schlage Control locks and standalone keypad systems that meet those audit requirements without the cost of full access control. For Montgomery Village townhomes, we favor mechanical push-button locks (Simplex, Lockey) where Wi-Fi reliability is spotty; they don’t need batteries or signal.
Keypad Lock
Keypad lock installation in Gaithersburg costs $160-$340 for residential models, $380-$620 for commercial-grade units with audit trails. The freeze-thaw cycles that hit exposed townhome entries in Montgomery Village and Lakelands make weather-sealed keypads worth the extra $40-$60 - cheaper units fail when moisture gets behind the membrane. We specify IP65-rated keypads for exterior doors and always check that the strike plate depth accommodates the thicker keypad escutcheon.
Biometric Lock
Biometric lock installation in Gaithersburg starts at $340 for a residential fingerprint deadbolt and runs to $890 for a multi-user commercial unit. These make sense for home offices used by cleared contractors who can’t risk lost keys, or for shared equipment rooms in biotech office parks along I-270. We don’t recommend biometric as a primary entry method for most Gaithersburg homes - the sensors struggle with cold, dry winter fingers - but they work well as secondary authentication on interior doors.
Key Duplication
Key duplication in Gaithersburg is $6-$18 for standard Kwikset or Schlage keys, $24-$48 for high-security restricted-keyway blanks like Medeco or Abloy Protec. Here’s where our location matters: Gaithersburg’s density of NIST employees and federal contractors means we stock restricted-key blanks that most locksmiths in Germantown or Rockville don’t carry. We duplicate Medeco Biaxial, Medeco M3, and Abloy Protec 2 on-site. If your key is stamped “Do Not Duplicate” and you don’t have the authorization card, we can’t cut it - that’s the restriction working as designed.

Trusted Brands We Service in Gaithersburg
We install and service Schlage, Kwikset, Medeco, and Abloy - brands we stock on every Gaithersburg service truck so you’re not waiting for a parts run. For the federal-contractor and biotech tenants along the I-270 corridor, we keep Medeco restricted-keyway cylinders and Abloy Protec 2 cores in inventory; these aren’t special-order items for us because they’re routine in this market. That means a rekey that might take three days elsewhere gets done today in Gaithersburg. We also carry smart-lock retrofit kits for the older door prep common in Montgomery Village and Lakelands townhomes, where the backset or bore diameter doesn’t match current standards.
Common Lock Installation & Rekey Problems We See in Gaithersburg Homes
- Freeze-thaw binding in Montgomery Village townhomes. The DC-area mid-Atlantic freeze-thaw pattern hits exposed entry doors hard each winter. Door frames swell and warp, making deadbolts difficult or impossible to throw. We see the predictable January-February spike across Montgomery Village and Lakelands. Often the fix isn’t just the lock - it’s adjusting the strike plate or planing the frame edge.
- Aging builder-grade locks from the 1970s-1990s. Original Kwikset and Schlage hardware in Gaithersburg’s planned communities has simply worn out. Springs lose tension, pins seize, and rekeying becomes impossible. We replace with Grade 2 commercial hardware that fits the same prep but lasts decades longer.
- Multi-unit lobby and mailbox systems past design life. Condo clusters around Kentlands and the Washingtonian Center installed electronic access systems 15-20 years ago. Those readers, controllers, and power supplies are failing. Simple rekeying won’t help - these need full access-control upgrades with modern Bluetooth or prox-card readers.
- HOA-required restricted-keyway conversions. Montgomery Village and some Kentlands HOAs now mandate Medeco or Mul-T-Lock cylinders for common-area doors to prevent unauthorized duplication. We handle the conversion, register the key codes with the factory, and provide the authorization cards your HOA needs on file.

FAQs - Lock Installation & Rekey in Gaithersburg
The freeze-thaw cycle warps your door frame, misaligning the bolt with the strike plate. This is predictable in Montgomery Village’s exposed townhome entries from January through February. We fix it by adjusting or replacing the strike, sometimes planing the frame edge - not just lubricating the lock, which is a temporary bandage. Call (877) 664-8139 and we’ll quote the repair flat; estimates are free.
Yes, if the locks are the same brand and keyway, we can rekey up to six cylinders to a single key in one visit for $180-$260. Kentlands homes often have mixed hardware from previous owners; if brands don’t match, we’ll tell you before we start and quote replacement options. Same-day service is available - call (877) 664-8139.
Medeco and Abloy Protec are the standards we see in Gaithersburg HOAs, particularly in Montgomery Village and Kentlands. Both prevent unauthorized duplication through factory-registered key codes. We stock both, handle the registration paperwork, and provide your HOA with the authorization cards. Installation runs $240-$380 per cylinder. Call for specifics on your HOA’s requirements.
Usually yes, but the door prep often needs modification. 1990s garden-apartment doors in Lakelands typically have 1-3/8″ bore holes or shallow backsets that don’t match current smart-lock specs. We carry adapter kits and can ream or deepen the prep on-site. Installation runs $280-$520 depending on the modification needed. We’ll assess this over the phone with a photo.
Yes, if you have the Medeco authorization card that came with your lock. We stock Medeco Biaxial and M3 blanks and duplicate them on-site for $24-$48 per key. Without the authorization card, we cannot cut restricted-keyway blanks - that’s the security feature working as designed. Bring your card and the original key to any service call, or call (877) 664-8139 to schedule.
