Locksmith in Arlington, MA
Arlington locksmith work follows a pattern shaped by the town’s housing stock: colonials and capes from the 1920s through the 1950s along Massachusetts Avenue, newer condominium buildings near Arlington Center, and multi-unit rentals clustered around the Cambridge and Somerville line. Homeowners here call a locksmith in Arlington most often for rekeys after a closing, deadbolt upgrades on older doors, and lockouts. Since 2002, Novak Lock & Security has handled all three with one rule: the price quoted on the phone is the price on the invoice. Call (331) 310-8471 for a firm quote before anyone is dispatched.
Why Arlington Homes Are Different
Arlington’s housing stock runs older than most of the Boston metro. Much of the town was built out before 1960, which means original mortise locksets on interior doors, narrow door preps that don’t accept modern cylindrical deadbolts without modification, and wood frames that have shifted over decades of New England freeze-thaw cycles. Arlington is also compact and dense, with many homes built on small lots and shared driveways, so technicians routinely work in tight entryways with limited door swing clearance. Parking is a real constraint: a service van near Arlington Center or along Mass Ave at peak hours means a technician may need to park a block away and walk tools to the door. In winter, older locks on north-facing entries seize more often than newer hardware, and in summer, painted wood doors swell on humid August days until the deadbolt won’t throw. These are the conditions that shape how we quote and how we work in Arlington.
Our Main Arlington Services
Two services account for most of the calls we take from Arlington homeowners: scheduled lock installation and rekey work, and emergency response for lockouts and failed hardware. Each has its own page with full pricing detail.
Lock Installation & Rekey in Arlington
When an Arlington home changes hands, the first call is usually a rekey. Older Arlingon doors often have worn Kwikset or Schlage cylinders that are still mechanically sound, and a rekey restores security without replacing hardware. For doors with original mortise locks or hardware past its service life, a new deadbolt or knobset makes sense. We quote per cylinder for rekeys and per opening for new hardware, in writing, before work starts. Full detail is on the Lock Installation & Rekey in Arlington page.

Emergency Locksmith in Arlington
Lockouts in Arlington happen at all hours, often in rental units near the Somerville line or in homes where the deadbolt finally fails after years of weather exposure. We answer the phone live around the clock and dispatch a background-checked technician directly to your address. The emergency call follows the same pricing rule as every other job: firm price on the phone, no change at the door. See Emergency Locksmith in Arlington for response specifics and costs.

Residential Locksmith in Arlington

Residential locksmith work in Arlington usually means one of two things: either a homeowner has just closed on one of the town’s 1920s colonial or 1950s cape homes and wants every exterior lock rekeyed before moving boxes in, or an older lock has finally quit after decades of New England weather. Many Arlington homes still carry original hardware, and some still have Kwikset knobs and single-cylinder deadbolts from a 1980s renovation. The security gap is real: a worn cylinder that has been rekeyed repeatedly over thirty years can be opened faster than a new one, and it fails without warning in a January cold snap. Our residential work follows the same pattern every time: we name the lock, name the grade, name the price, then do the job. You can read more about the full residential scope on our Residential Locksmith hub page, but here is how it breaks down in Arlington specifically.
Lock Rekey
Signs you need it
You just bought a home in Arlington, you’ve lost a key, or a roommate or tenant moved out and you don’t know who still has copies.
What it costs in Arlington
Lock rekeying in Arlington typically runs $25-$45 per cylinder for standard locks, plus a service call fee, and high-security cylinders run $50-$90 each.
How we do it
We remove the cylinder, swap the pins to a new key, test the key in the lock, and hand you all copies before we leave.
Deadbolt Installation
Signs you need it
Your entry has only a knob lock, the deadbolt is loose or won’t extend, or the strike plate has pulled away from a weathered Arlington door frame.
What it costs in Arlington
Deadbolt installation in Arlington runs $45-$95 for standard hardware, and $120-$250 per lock for high-security deadbolts like Medeco or Mul-T-Lock.
How we do it
We bore or enlarge the door prep, install the deadbolt and reinforced strike plate, and test the throw under real door pressure.
Residential Lockout
Signs you need it
You’re standing outside an Arlington home without a working key, or the key turns but the deadbolt won’t retract.
What it costs in Arlington
Residential lockout service in Arlington typically runs $75-$150 during normal hours, with emergency dispatch priced on the phone before we send anyone.
How we do it
We open the door without damaging the lock where possible, verify your right to enter, and leave you with a documented photo record of the work.
What Residential Locksmith Costs in Arlington
| Item | Typical range in Arlington |
|---|---|
| Lock rekey (standard cylinder) | $25-$45 per cylinder |
| Deadbolt installation (standard) | $45-$95 per lock |
| Residential lockout | $75-$150 per call |
Is a rekey enough for an Arlington home, or do I need new locks?
A rekey is enough if the existing hardware is mechanically sound. If the deadbolt is loose, the cylinder is worn, or the strike plate is pulling from an old Arlington frame, replacement is the better spend.
Do you rekey all locks in an Arlington house to one key?
Yes. We can key all exterior doors to a single key while still giving you separate keys for interior doors if needed. The price is set per cylinder, so you know the total before we begin.
Commercial Locksmith in Arlington

Commercial locksmith work in Arlington centers on the retail and office spaces along Massachusetts Avenue, the medical and professional buildings near Arlington Center, and the small apartment buildings that line Broadway and the side streets toward Cambridge. These buildings share a common problem: older doors with mixed hardware generations, where one entrance has a 1990s Schlage and the next has a high-security cylinder added in 2015. The specific challenge in Arlington is that many storefronts and offices occupy converted residential structures, so commercial and residential hardware sit side by side. We work both, in the same visit, with a written scope and a flat per-lock price. Our Commercial Locksmith page covers the full commercial range; the Arlington specifics are below.
Commercial Lockout
Signs you need it
An employee left a key inside, a key broke off in a storefront cylinder, or a morning opening reveals a lock that won’t turn.
What it costs in Arlington
Commercial lockout service in Arlington typically runs $95-$200 during business hours, with after-hours dispatch quoted firm on the phone.
How we do it
We open the door, document the hardware condition, and recommend whether the lock can stay in service or needs repair.
Panic Bar Installation
Signs you need it
A fire marshal or building inspector has flagged an exit door, or a staff door needs one-motion egress that a deadbolt cannot provide.
What it costs in Arlington
Panic bar installation in Arlington runs $350-$800 per door including hardware, depending on door width and existing prep.
How we do it
We measure the opening, install the bar and strike, and test that the door exits cleanly from the inside every time.
What Commercial Locksmith Costs in Arlington
| Item | Typical range in Arlington |
|---|---|
| Commercial lockout | $95-$200 per call |
| Panic bar installation | $350-$800 per door |
| Commercial rekey | $30-$60 per cylinder |
Can you rekey a commercial space in Arlington after a tenant leaves?
Yes. We rekey each door at $30-$60 per cylinder and can key a master system so you keep building access while the tenant’s keys stop working. The written quote lists every opening.
Do you handle master key systems for Arlington apartment buildings?
We do. We survey the building, design the key hierarchy, and install cylinders to match. The work is scheduled, not dispatch-based, and priced per lock before we cut a single key.
Automotive Locksmith in Arlington

Automotive locksmith work in Arlington follows the same map as the town itself: cars parked on streets and in small driveways near Massachusetts Avenue, at the Arlington Center lots, and in residential neighborhoods off Park Avenue. The most common call is a lockout, usually in a driveway or a public lot, followed by key replacement for cars where the only key has worn down to the point it no longer turns the ignition. New England winters accelerate that wear: salt and cold make lock cylinders and door handles brittle, and a frozen door lock is a routine January call in Arlington. See the Automotive Locksmith hub for the full automotive scope, and below for the two sub-jobs we handle most in Arlington.
Car Lockout
Signs you need it
Keys are locked inside the car, the key is broken in the door, or the lock has frozen shut in an Arlington cold snap.
What it costs in Arlington
Car lockout service in Arlington typically runs $50-$100 during normal hours, with more for after-dark or holiday response.
How we do it
We open the vehicle with non-damaging tools, verify ownership, and test the lock before we leave.
Key Fob Programming
Signs you need it
A new fob won’t start the car, a replacement fob works manually but won’t unlock remotely, or the vehicle no longer recognizes the original fob.
What it costs in Arlington
Key fob programming in Arlington runs $75-$175 per fob, depending on the vehicle’s year and system, plus any fob cost if we supply it.
How we do it
We connect to the vehicle, program the fob to the car’s immobilizer, and test both remote and ignition functions before handing it back.
What Automotive Locksmith Costs in Arlington
| Item | Typical range in Arlington |
|---|---|
| Car lockout | $50-$100 per call |
| Key fob programming | $75-$175 per fob |
| Car key replacement | $85-$175 per key |
Can you make a new car key in Arlington if I lost all my keys?
Yes. We cut and program a new key from the vehicle’s VIN and immobilizer data. The job runs $85-$175 for most keys, and we quote the exact figure before dispatch.
Do you come to my driveway in Arlington for a car lockout?
We do. Mobile service means we come to the car wherever it is in Arlington, open it, and leave you with a documented record of the work. No tow, no shop visit.

What pushes a price up in Arlington is usually the age of the hardware: narrow preps on 1920s doors, mortise locks that need retrofitting, or weather-damaged frames that require strike plate reinforcement. Every quote includes the full price before we dispatch, and the technician is not permitted to change it at the door. That has been the rule since 2002, and it is the rule on every Arlington job.
