We’re Strongbox Lock & Safe Co., and we’ve been helping Arlington homeowners secure pre-WWII houses, triple-decker condos, and everything between for over 42 years.

Arlington’s streets are familiar territory for our team. We know the narrow driveways off Mass Ave, the condo-converted triple-deckers near Broadway, and the swollen door frames in East Arlington that shift with every freeze-thaw cycle. That local knowledge saves you time and money. We don’t guess at what your century-old mortise lock needs - we’ve already serviced hundreds just like it in Arlington homes.
Why Strongbox Lock & Safe Co. Is Arlington’s Preferred Lock Installation & Rekey Company
Our reputation in Arlington was built one job at a time, mostly by homeowners who called us after a bad experience elsewhere. They remember the $19-ad locksmith who showed up in an unmarked car and tripled the price on site. We’re the flat-price alternative. The price we quote on the phone is the price on the invoice. Period.
Arlington customers specifically mention our technicians showing ID at the door in reviews. That’s not accidental - it’s policy. Every Strongbox technician is background-checked, uniformed, and carries company identification. In a town where you’re handing keys to someone who’ll access your pre-WWII home, that verification matters.
Response time to Arlington averages 25-40 minutes from dispatch, depending on whether you’re in East Arlington near the Cambridge line or farther west toward Lexington. We keep common cylinders, mortise lock parts, and smart-lock adapter kits stocked for Arlington’s specific housing stock, which cuts return visits.
We also know the local quirks: which Arlington triple-deckers still run original Corbin rim cylinders, where condo associations require master-key compatibility, and how the road salt tracked into unprotected triple-decker entryways corrodes keyways by February. That expertise comes only from working here regularly, not from a manual.
Our Lock Installation & Rekey Services in Arlington
Smart Lock Installation
Smart lock installation in Arlington presents a specific challenge: most smart locks are engineered for modern 2-3/8″ backset doors, while Arlington’s pre-WWII triple-deckers often have 2-3/4″ or even 5″ backsets in their original mortise prep. We recently rekeyed a 1920s mortise lock on a Mass Ave triple-decker. The original Corbin rim cylinder was seized from winter salt, and the owner wanted a Schlage smart lock. We installed a Baldwin mortise lock with a Schlage deadbolt conversion kit that fit the old door prep without widening the bore hole - saving the original door jamb. That’s the kind of custom solution a big-box installer won’t attempt. A typical smart lock retrofit in Arlington runs $220-$420, including adapter hardware.
Keyless Entry Systems
Keyless entry is popular among Arlington’s condo owners who want to eliminate lockout calls from tenants or Airbnb guests. But keyless entry on a triple-decker’s original mortise door requires careful planning. The electronics need clean mounting surfaces, and Arlington’s warped old jambs often need reinforcement first. We assess whether your door can support a keypad or whether a separate deadbolt installation makes more sense. Most keyless entry installations in Arlington fall between $180-$340. If your jamb is rotted from years of snow infiltration, we’ll tell you upfront - no surprise carpentry charges after we arrive.
Keypad Lock Installation
Keypad locks offer a middle ground: no phone dependency, no biometric fuss, just a code. For Arlington’s older housing stock, we favor keypad deadbolts from Schlage and Kwikset with retrofit-friendly dimensions. We’ve installed dozens along Mass Ave and the side streets off Broadway where condo conversions have multiplied. One building can generate three separate keypad lock calls within months as new owners buy in. We keep records of which units we’ve serviced to help property managers maintain key control. Expect $160-$290 for most keypad installations in Arlington.
Biometric Lock Installation
Biometric locks - fingerprint readers - are less common in Arlington’s older buildings but growing among homeowners who’ve renovated their kitchens and want the entry to match. The challenge is power: biometric locks need consistent battery performance, and Arlington’s unheated entryways can drain cells fast in January. We specify cold-rated models and can wire low-voltage power where practical. Biometric installation in Arlington typically runs $280-$450.
Electronic Lock Repair & Rekey
Electronic locks in Arlington fail for two predictable reasons: corrosion from tracked-in salt, and misalignment from seasonal frame shifting. We service electronic lock brands including Schlage, Yale, and Baldwin, and we stock replacement keypads and circuit boards for faster turnaround. Most electronic lock repairs in Arlington cost $120-$240.
Key Duplication
Key duplication in Arlington isn’t always straightforward. Original mortise lock keys, Corbin rim cylinder keys, and some older Schlage wafer keys require specific blanks that hardware stores no longer stock. We carry the full range, including restricted keyway blanks for Medeco and Mul-T-Lock systems. Standard key duplication runs $4-$12 per key; restricted or vintage blanks run $15-$35.

Trusted Brands We Service in Arlington
We install and service Schlage, Kwikset, Medeco, Abloy, Baldwin, Yale, Mul-T-Lock, and Sargent - and we keep common parts for all of them on our Arlington-area service vehicles. That inventory matters when your 1920s Corbin cylinder needs a compatible modern replacement or when your condo association specifies Medeco high-security key control. We don’t show up with whatever’s on the truck and hope it fits. We ask the right questions when you call, confirm your hardware, and arrive prepared. For Arlington’s vintage housing stock, that preparation is the difference between a one-hour job and a two-visit ordeal.
Common Lock Installation & Rekey Problems We See in Arlington Homes
- Seasonal deadbolt misalignment from freeze-thaw cycles. Greater Boston’s hard freeze-thaw cycles cause wooden door frames in Arlington’s older homes to swell and shift seasonally, regularly throwing deadbolt throws out of alignment with strike plates. Calls spike every late fall and early spring, especially in East Arlington triple-deckers with unheated entries.
- Corroded keyways from road and sidewalk salt. Road and sidewalk salt accelerates corrosion on exterior keyways and pins in the unprotected entryways common on Arlington triple-deckers. By February, we’re replacing cylinders that seized solid - often original Corbin or Yale hardware from the 1930s.
- Smart-lock retrofit gaps in mortise preps. Retrofitting a smart lock into a 1940s mortise prep without proper adapter plates leaves gaps that allow lever twisting or tailpiece breaking. We’ve fixed too many DIY and cut-rate installs where the lock looked fine but the mechanism was destroying itself.
- Condo conversion key-control failures. Condo-converted building key systems fail when one new owner rekeys their unit with a standard deadbolt that doesn’t match the master-keyed mortise locks on common doors. We’ve rebuilt master key systems for entire Arlington triple-deckers after a single incompatible lock created a security gap.

FAQs - Lock Installation & Rekey in Arlington
Yes - in most cases, we can install a keypad lock that fits your existing mortise prep using adapter plates or a mortise-specific keypad like certain Baldwin models. We assess the backset, door thickness, and jamb condition before recommending hardware. Arlington’s pre-WWII triple-deckers often have 80-year-old mortise locksets with non-standard backsets - typically 2-3/4″ or 5″ rather than the modern 2-3/8″ standard - requiring custom solutions for smart-lock retrofits. We’ve preserved original doors on dozens of Arlington properties. Call (877) 664-8139 to describe your setup and get a flat quote.
Your wooden door frame is swelling and shifting with freeze-thaw cycles, throwing the deadbolt throw out of alignment with the strike plate. This is one of the most common calls we get every November and March in East Arlington triple-deckers. We can adjust or reposition the strike, and sometimes recommend a weatherstripping upgrade to reduce moisture infiltration. If the frame is badly warped, we may suggest a reinforced jamb prep. The fix typically runs $85-$160. Call (877) 664-8139 before it gets worse - a binding deadbolt you force will eventually break.
You can rekey a standard deadbolt yourself with a kit, but Arlington’s converted triple-deckers rarely have standard setups. Condo conversions of triple-deckers along Mass Ave and the streets off Broadway have surged, meaning a single building can generate a locksmith call from three different owners within months of each other - each new owner wanting a rekey or smart-lock retrofit on doors that still have 80-year-old mortise prep and no standard backset. If your unit connects to common areas with master-keyed mortise locks, a DIY change can compromise building security and violate your association agreement. We coordinate with property managers and install compatible hardware. Call (877) 664-8139 for a free assessment.
Yes - we stock compatible Corbin rim cylinder replacements and can often source original-spec parts for full restoration. Many Arlington triple-deckers still run these cylinders, and we’ve rebuilt them from seized, salt-corroded condition. If the cylinder is beyond repair, we match the replacement to your existing keying or rekey the entire system. Vintage cylinder work runs $160-$320 depending on parts availability. Call (877) 664-8139 with your Corbin model number if you can find it.
Not safely on a rotted jamb - keyless entry hardware needs solid mounting surfaces to resist forced entry. We can reinforce or replace the jamb first, then install the keyless system. For Arlington rentals, we also ensure the hardware supports landlord override codes and audit trails where needed. Combined jamb repair and keyless installation typically runs $280-$480. We provide a written quote before starting, and every job is backed by our 90-Day Done Right Promise. Call (877) 664-8139 to schedule.
