Why Strongbox Lock & Safe Co. Is Somerville’s Preferred Lock Installation & Rekey Company
Somerville residents know the bait-and-switch game. The $19-ad locksmith who shows up in an unmarked car, invents a “drilling fee,” and charges triple the quote. We’ve built our name as a trusted Somerville Residential Locksmith by doing the opposite.
Our technicians are background-checked, uniformed, and present company ID at your door on every visit. The price we quote on the phone is the price on the invoice - a square deal, no exceptions. Every job carries our 90-Day Done Right Promise, backed in writing with no paperwork and no arguing. If it’s not right, we come back.
Calls are answered by a live person, including nights, weekends, and holidays. No voicemail trees. No callback queues. When you’re locked out on Highland Avenue at midnight or need a rekey done before your tenant moves in on Elm Street, we answer.
We’ve served Somerville and surrounding communities for over 42 years. Our vans carry the specific mortise cylinders, adapter plates, and strike hardware that Somerville’s 1880-1920 housing stock demands - not just whatever was cheapest at the supply house.
Our Lock Installation & Rekey Services in Somerville
Smart Lock Installation
Installing a smart lock on a Somerville triple-decker isn’t a screwdriver job. The original mortise pockets in these 120-year-old doors rarely align with contemporary smart lock footprints, and the wood frames have settled in ways that make standard templates useless. We machine custom adapter plates in our shop to bridge the gap between vintage door anatomy and modern hardware. On a recent Davis Square job, we fitted a Schlage smart lock to a carriage-house-style front door with a non-standard cylinder bore, then ran low-voltage wiring to the vestibule for integrated smart-home control. The owner now unlocks from their phone, and the door still looks like it belongs on a Victorian.
Keyless Entry
Keyless entry systems eliminate the September 1 key handoff scramble that defines Somerville’s rental calendar. For landlords managing triple-deckers in Winter Hill or Teele Square, we install keypad and RFID systems that let you revoke access codes remotely between tenants - no rekeying, no lockouts, no tracking down spare keys. We favor Schlage and Kwikset keyless hardware for Somerville’s climate, since their sealed electronics hold up better than budget brands through our freeze-thaw cycles. Every install includes strike plate realignment to account for seasonal wood movement, so your keyless entry works in February as smoothly as it did in September.
Keypad Lock Installation
Keypad locks suit Somerville’s multi-unit buildings where three households share a vestibule. We install standalone and networked keypad systems for entry doors, basement storage areas, and shared laundry rooms throughout 02143, 02144, and 02145. For commercial properties near Union Square or along Broadway, our Commercial Locksmith in Somerville specifies Medeco or Sargent keypad hardware with audit-trail logging - you know exactly who entered and when. Our installs include weatherproofing for exterior keypads exposed to Somerville’s salt air and freeze-thaw punishment.
Biometric Lock Installation
Biometric locks - fingerprint readers, facial recognition - are increasingly requested for Somerville’s renovated condos and owner-occupied triple-decker units. These systems demand precise door prep and stable mounting surfaces, which makes them a poor fit for handyman installation on century-old doors. We assess frame integrity, reinforce weakened jambs, and machine custom mounting plates when the original lock pocket won’t accommodate the biometric housing. For Somerville’s high-turnover rental market, we typically recommend biometric systems for owner-occupants rather than rentals, since fingerprint enrollment between tenants is more involved than a simple rekey.
Electronic Lock Repair & Rekey
Somerville’s electronic locks take a beating. Batteries corrode in unheated vestibules. Circuit boards crack when over-torqued into warped door frames. As your Automotive Locksmith - Somerville team, we also repair and rekey electronic locksets from all major manufacturers, and we stock replacement components for faster turnaround than ordering from a warehouse. If your electronic lock is failing, we diagnose whether the issue is the lock, the wiring, or the door itself - because replacing a $400 lock when the real problem is a swollen jamb is a waste we won’t let you make.
Key Duplication
Our key duplication service covers standard Kwikset and Schlage keys, high-security Medeco blanks, and the antique mortise keyways still common in Somerville’s older buildings. We cut by code for precision, not by eye, and we verify every duplicate in the lock before you leave. For landlords preparing for September 1, we duplicate master key sets and tenant keys in quantity, labeled by unit. Seniors and veterans receive our standing 5% discount on all key duplication.

Trusted Brands We Service in Somerville
We install and service Schlage, Medeco, Kwikset, and Abloy hardware - brands we’ve specified for Somerville’s specific conditions for decades. Schlage smart locks and keyless entry systems handle our freeze-thaw cycles well. Medeco’s high-security cylinders resist the picking and bumping that target Somerville’s high-turnover rental buildings. Abloy’s rotating disc mechanisms perform reliably in the humid, salt-exposed vestibules common near the Mystic River. We stock parts for all four brands on our Somerville vans, which means most repairs finish same-day without waiting for a warehouse shipment.
Common Lock Installation & Rekey Problems We See in Somerville Homes
- Moisture-trapping gaps from mismatched deadbolts. Installing a standard deadbolt into a mortise lock pocket designed for a rim lock leaves exposed gaps that trap condensation against the door. In Somerville’s triple-deckers, this moisture warps the wood, swells the frame, and turns a simple lock upgrade into a door replacement. We machine adapter plates that seal the pocket and carry moisture away from the wood.
- Freeze-thaw strike plate seizure. Somerville’s classic New England freeze-thaw cycle causes the wood frames of triple-deckers to swell in winter and contract in summer, progressively misaligning deadbolts and strike plates in buildings that were already built with minimal tolerances. A strike plate installed in September can seize by December, locking tenants out. We adjust for seasonal movement and specify strikes with slotted mounting holes that allow winter readjustment without re-drilling.
- Split jambs from over-torquing. Century-old pine door jambs in Somerville’s Victorian housing can’t handle the torque that modern installation guides specify for steel doors. Over-tighten mounting screws and the jamb splits, requiring full strike plate relocation and wood filler that never matches. We pilot-drill to reduced depth and use shorter fasteners spec’d for antique wood.
- Obsolete mortise cylinders during September rush. The annual September 1 lease turnover compresses enormous rekey demand into 48 hours. Many Somerville landlords discover too late that their triple-decker’s antique mortise cylinders haven’t been made since 1960. We stock the most common obsolete mortise cylinders on our vans specifically for this surge, and we maintain relationships with specialty suppliers for the rare ones.

FAQs - Lock Installation & Rekey in Somerville
Yes, but it requires custom fabrication. We machine adapter plates that bridge between the mortise pocket and modern smart lock footprints, then seal the gaps to prevent moisture damage to the wood. On a recent Davis Square job, we fitted a Schlage smart lock to a Victorian carriage-house door with a non-standard bore, then ran low-voltage wiring for smart-home integration. Call (877) 664-8139 to discuss your specific door - estimates are free.
Somerville’s freeze-thaw cycle swells wood frames in winter, misaligning strike plates that were set during September’s milder weather. The minimal tolerances in 1880-1920 construction leave no margin for this movement. We adjust strikes with slotted holes that allow seasonal readjustment, and we account for winter expansion during fall installations. If your September rekey has turned into a December lockout, call us - we can usually fix the alignment without replacing hardware.
Yes. We carry the most common obsolete mortise cylinders on our vans specifically for Somerville’s September 1 surge, and we maintain specialty supplier relationships for the rare variants. If you’re a landlord with a Winter Hill or Spring Hill triple-decker facing tenant turnover, call early - our stock moves fast that week, and the flat price we quote holds even during peak demand.
Yes, if all three locks share compatible keyways. We can set up a master key system where you carry one key for all units and tenants have keys that work only their door. For Somerville’s September 1 turnover, this eliminates the key handoff scramble and reduces rekeying costs between tenants. We’ll inspect your existing hardware and quote the master key setup on the phone - call (877) 664-8139.
For Somerville’s original carriage-house doors, we typically recommend Schlage smart locks with custom adapter plates for mortise pockets, or Medeco high-security cylinders if you’re keeping the original hardware. The right choice depends on door condition, smart-home integration goals, and whether the frame can handle modern torque loads. We assess in person and quote flat - no obligation, no pressure.
