Why Arlington Homes Are Different
Arlington’s housing stock is overwhelmingly pre-WWII, with a high concentration of triple-deckers and Victorian/Colonial-era homes that frequently retain original mortise locksets from the 1920s-1940s. A locksmith here must be fluent in vintage mortise hardware - sourcing compatible cylinders, repairing aging case mechanisms, and advising on modern security upgrades that fit antique door prep - skills that are far less in demand just a few miles out in newer suburbs like Burlington or Woburn.
The Greater Boston freeze-thaw cycle hits Arlington’s wooden door frames hard. Every late fall and early spring, we field calls from homeowners on streets like Broadway and Massachusetts Avenue whose deadbolts suddenly won’t throw because the frame has swollen half an inch. Road salt, tracked into the unprotected entryways common on triple-deckers, corrodes exterior keyways and pins faster than in sheltered suburban entries. And the condo conversions keep coming: a single triple-decker along Mass Ave can generate three separate rekey calls within months, each new owner discovering the limits of 80-year-old hardware.
Residential Locksmith in Arlington
We handle residential locksmith work throughout Arlington’s 02474 and 02476 ZIP codes, from standard rekeys to full mortise rebuilds on century-old doors. Our technicians carry the pin kits, follower tools, and replacement cylinders needed for vintage Yale, Sargent, and Corbin hardware - we don’t leave you waiting for parts while your front door sits unsecured.
Lock Rekeying
Rekeying is the right move when you need new keys without replacing hardware - after a move, a tenant change, or a lost key. In Arlington, we rekey everything from standard Kwikset deadbolts to original mortise locks from the 1930s. A standard rekey runs $89-$150, while vintage mortise rekeys run $120-$200 due to the specialized pinning and cylinder fitting required. We recently rekeyed a triple-decker on Mass Ave in East Arlington where all three units had different original mortise locks - one Sargent, two Yale - dating to the 1930s. We sourced compatible cylinders and replaced worn pins while preserving the original case mechanisms.
Deadbolt Installation & Door Reinforcement
Arlington’s older doors often lack proper deadbolt prep, or the existing hole doesn’t align with modern hardware. We measure the backset, check jamb thickness, and address warped frames before installing anything. A standard deadbolt installation costs $150-$250, with premium options like Medeco running higher. Door reinforcement - longer screws, strike boxes, wrap plates for split jambs - typically runs $180-$340. We won’t install a deadbolt that won’t throw cleanly. That’s how you get lockouts in February when the frame swells.
Do you service original mortise locks in Arlington’s older homes?
Yes. We repair, rekey, and rebuild original mortise locks from the 1920s-1940s, including sourcing compatible cylinders and replacing worn internal components while preserving the original case. Arlington’s triple-deckers and Victorians are full of these locks, and we’ve worked on hundreds of them. Call (877) 664-8139 to describe what you have - we can usually tell you over the phone whether it’s a candidate for repair.
Commercial Locksmith in Arlington
Commercial lock repair and installation in Arlington typically costs $180-$550 depending on the hardware, and our technicians can usually reach businesses in the 02474 and 02476 ZIP codes within 30-45 minutes during business hours. We handle commercial locksmith work for offices, retail spaces, and condo associations - anywhere key control and code compliance matter.
Master Key Systems
Arlington’s triple-decker condo conversions create complex key-control situations. One building, three units, three different owners, and often three different original keys for doors that share a common vestibule. We design master key systems that give each owner independent access while letting the property manager maintain override control. A three-level master key system for six locks typically runs $340-$550. We recently completed this exact setup for a Broadway triple-decker where each unit had a different vintage mortise lock.
High-Security & Panic Hardware
Standard hardware store locks don’t cut it for Arlington commercial properties with multiple tenants. We install Medeco and other restricted-keyway systems that prevent unauthorized duplication. Fitting these modern cylinders into warped, century-old jambs requires reinforced strikes and adjustable backsets. Panic bar installation on standard prep runs $380-$620; custom jamb modification for non-standard frames adds $170-$270. We review Massachusetts fire code compliance during every estimate.
Can you install a modern panic bar on a 1920s Arlington triple-decker door?
Yes, we install panic bars on non-standard Arlington frames regularly, though it typically requires custom jamb modification that adds $170-$270 to the base installation cost. We measure the original mortise prep, source compatible hardware from Sargent or Yale, and modify only what’s necessary to meet Massachusetts fire code without destroying the door’s character. Call (877) 664-8139 to schedule a free on-site assessment.
Automotive Locksmith in Arlington
Automotive locksmith service in Arlington typically costs between $89 and $340 depending on the job, and most car lockouts and key replacements are completed same day. We dispatch automotive locksmith technicians to Arlington’s triple-decker neighborhoods and Mass Ave corridor with mobile programming equipment for transponder keys and fobs.
Car Lockouts & Key Replacement
Locked your keys in the car on a February morning near Arlington Center? We answer live and get you back inside without damaging the vehicle. A standard car lockout runs $89-$140. Key replacement for older vehicles common in Arlington - 1990s-era Hondas and Toyotas kept as second cars - typically runs $120-$180. We stock blanks and cut on-site.
Transponder Programming
Modern vehicles rely on transponder chips for ignition security. When that chip fails, the vehicle won’t start even with a physical turn. Our mobile programming equipment covers most domestic and import brands. Transponder key programming runs $180-$280, and key fob programming runs $150-$240. Arlington’s freeze-thaw cycles and road salt exposure accelerate wear on these systems, especially in vehicles with unprotected exterior locks.
Why do my car keys get stuck in the ignition after winter in Arlington?
Moisture and road salt work into the ignition cylinder over months of cold-weather driving, causing corrosion and pin binding that peaks in late winter. The freeze-thaw cycles that warp Arlington’s wooden door frames also affect metal components in your vehicle. If your key sticks, don’t force it. Ignition repair runs $180-$280. Call (877) 664-8139 - we can extract broken keys, clean the cylinder, or replace it if corrosion is too advanced.
Lock Installation & Rekey in Arlington
Lock installation and rekeying in Arlington typically runs $140-$380 for most residential jobs, with same-day service available throughout the 02474 and 02476 ZIP codes. We handle lock installation and rekey work on everything from standard modern doors to century-old mortise preps that require custom solutions.
Smart Lock Retrofits
Most smart locks assume a modern 2-3/8″ backset, while Arlington’s pre-WWII triple-deckers often have 2-3/4″ or even 5″ backsets in original mortise prep. We recently installed a Baldwin mortise lock with a Schlage deadbolt conversion kit on a Mass Ave triple-decker - fitting the old door prep without widening the bore hole. Smart lock retrofits with adapter kits run $220-$420. We assess whether your door can support the hardware or if reinforcement is needed first.
Keyless Entry & Keypad Locks
Keyless entry is popular among Arlington’s condo owners, but the electronics need clean mounting surfaces and Arlington’s warped old jambs often need reinforcement first. Most keyless entry installations fall between $180-$340. Keypad locks from Schlage and Kwikset offer a simpler retrofit for older housing stock, typically running $160-$290. We’ve installed dozens along Mass Ave and the streets off Broadway where condo conversions have multiplied.
My Arlington triple-decker has original mortise locks. Can you install a keypad lock without ruining the antique door?
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, requiring custom solutions for smart-lock retrofits. Call (877) 664-8139 for a free evaluation.
Emergency Locksmith in Arlington
Locked out at midnight? Broken key in a vintage mortise lock? We answer every emergency locksmith call with a live person, 24/7, and quote your flat price before our truck rolls. We know Arlington’s streets well enough to find your door without delay - from the triple-deckers along Mass Ave to the Colonials off Broadway.
24/7 Lockout Response
House lockouts don’t keep office hours. We don’t either. Whether you’re standing outside your triple-decker on Brooks Street at 2 a.m. or locked out of your condo near the Arlington Center T stop on a Sunday morning, a live dispatcher takes your call and sends the nearest technician. A standard house lockout runs $95-$165 during daytime hours; overnight and holiday calls run $145-$220. We carry the full range of picks and bypass tools to open your door without drilling whenever possible.
Broken Key Extraction & Safe Opening
Arlington’s freeze-thaw cycles warp old door frames twice yearly, throwing deadbolt alignment off and stressing keys already worn thin by decades of use. A key snapping off in the cylinder is a common emergency call, especially in late November and March. Broken key extraction runs $120-$195. We also open safes in Arlington’s older homes - floor safes in moisture-prone basements, wall safes behind built-in cabinetry - generally ranging from $185-$450 depending on type and condition.
Every winter my deadbolt gets stuck and I can’t get in. Is this common in Arlington?
Yes, this is one of the most common emergency calls we receive in Arlington from November through March. The freeze-thaw cycle swells wooden door frames in pre-WWII homes, shifting the strike plate alignment and binding the deadbolt throw. We adjust the strike, realign the bolt path, and can install a weather-resistant cylinder if corrosion is also a factor. The fix typically takes 20-30 minutes and costs $95-$165. Call (877) 664-8139 - we respond same day.

What Arlington Customers Say
"Programmed a transponder key for an older car that the dealership wanted an absurd number for. Same key, fraction of the price, twenty minutes in my driveway."
- Adriana Herrera"The deadbolt had been mounted crooked by whoever lived here before and had stuck for years. He redrilled and reset it properly rather than just swapping the hardware."
- Carrie Pruitt"Got me back in and the price was fair for the hour. He arrived closer to forty five minutes than the twenty he estimated, which feels long standing outside, though he was honest that traffic was the problem."
- Todd Gallagher
