Locksmith in Lexington, MA
Lexington locksmith work splits into two worlds: 18th-century colonial hardware around the Battle Green and modern smart-lock retrofits on rebuilt luxury homes. We handle residential lockouts, rekeys, deadbolt installs, and high-security cylinder upgrades for homeowners across Lexington, including the vintage mortise locks that chain-store hardware simply can’t replace. The phone line is answered by a person, day or night, at (331) 310-8471.
Why Lexington Homes Are Different
Lexington’s housing stock spans two centuries, and the age of the door tells you what the locksmith will find. Around the Battle Green Historic District, many homes are genuine Federal and Colonial-period structures. Their mortise lock cases and escutcheons are often considered character-defining under local preservation guidelines, which means a homeowner cannot just drill out a failed lock and drop in a modern cylindrical deadbolt without losing historic fabric. We stock Corbin and Yale mortise components specifically for these jobs.
Then there are the mid-century neighborhoods: Peacock Farm and Turning Mill, where 1950s and 1970s ranches and split-levels still carry their original builder-grade Kwikset hardware. The surrounding property values have risen sharply, but the lock cylinders are often the same entry-grade units installed when the houses were built. A rising share of Lexington work now involves European multi-point locking doors on teardown-rebuild projects, which require different tooling and a different skill set than a standard American deadbolt. The New England freeze-thaw cycle compounds every issue: roughly 48 inches of annual snowfall and repeated overnight drops below 20°F cause wooden door frames to swell in autumn and contract in January, which chronically misaligns strike plates and stresses deadbolt throws. January and February produce a predictable surge in lockout calls across Lexington.
Our Main Lexington Services
Two jobs dominate the Lexington call volume: rekeys for new homeowners and emergency lockouts, most often on the coldest nights of the year. Each has its own dedicated page with full pricing detail.
Lock Installation & Rekey in Lexington
New homeowners in Lexington almost always need a rekey. The previous owner may have handed over two keys, but there’s no way to know how many copies exist. A full rekey replaces the internal pins so every old key stops working, and new keys work from day one. For older Lexington homes with mortise locks, rekeying requires disassembling the mortise case correctly so the original hardware is preserved. Read the full scope and pricing on the Lock Installation & Rekey in Lexington page.
Emergency Locksmith in Lexington
A lockout in Lexington in January is not a mild inconvenience. With exterior keyways iced over and temperatures dropping fast, a locked-out homeowner needs a technician who carries automotive and residential entry tools and arrives with a documented written price. We answer the phone around the clock, and the dispatcher quotes a firm price before anyone is sent. Details are on the Emergency Locksmith in Lexington page.

Residential Locksmith in Lexington
Residential locksmith work in Lexington is shaped by the age of the housing stock and the freeze-thaw cycle that stresses every exterior door. Many 18th- and 19th-century colonials near the Battle Green still carry original mortise lock bodies, while mid-century ranches in Peacock Farm and Turning Mill hold onto builder-grade Kwikset cylinders long past their useful life. When we rekey or replace a Lexington lock, we are working with hardware that has often survived 60, 80, or 200 New England winters, and we treat the door and the frame as part of the job. This is the daily work of our Residential Locksmith team.
Lock Rekey
Signs you need it
You’ve moved into a Lexington home and you don’t know how many people the previous owners gave keys to.
What it costs in Lexington
Lock rekeying in Lexington typically runs $75-$150 for the first cylinder and $55-$100 for each additional cylinder keyed alike, quoted in writing before we touch the lock.
How we do it
We remove the cylinder, replace the internal pins to match new keys, reassemble, and test every key on site, leaving a documented photo record.
Deadbolt Installation
Signs you need it
Your Lexington exterior door has only a knob lock, or the existing deadbolt throw no longer seats fully in the strike plate.
What it costs in Lexington
New deadbolt installation in Lexington typically runs $110-$200 per lock for a standard deadbolt, with high-security cylinders priced separately and higher.
How we do it
We drill the door and frame to spec, set the strike plate so the throw seats fully even on a frame that has shifted with the seasons, and test multiple cycles.
Residential Lockout
Signs you need it
You’re standing outside your Lexington home in the cold, your keys are inside, and no one else has a copy.
What it costs in Lexington
Residential lockout service in Lexington typically runs $85-$180, depending on time of day and whether the keyway is iced over, priced in writing before dispatch.
How we do it
A uniformed technician verifies residency, opens the door without damaging the lock when possible, and offers a rekey on the spot if key control is uncertain.
What Residential Locksmith Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Lock rekey (first cylinder) | $75-$150 |
| Additional cylinders keyed alike | $55-$100 each |
| Deadbolt installation (standard) | $110-$200 |
How fast can you get to a Lexington home?
Most residential calls in Lexington are reached within 30 to 45 minutes, though January and February nights can run longer. Call (331) 310-8471 for the current response window and a firm price before anyone is dispatched.
Do you rekey mortise locks on old Lexington colonials?
Yes. We carry Corbin and Yale mortise components and rekey many 19th-century lock bodies in the Battle Green historic district without replacing the character-defining hardware. The original case and escutcheon stay in place.
Commercial Locksmith in Lexington
Lexington commercial locksmith work runs from storefronts in the town center to office and medical suites along Massachusetts Avenue. The mix of older buildings and newer commercial fit-outs means a single building can have vintage mortise hardware on one door and an access control reader on the next. We schedule commercial jobs with a written scope and a flat per-lock price, because a business owner should know the full cost before a screw is turned. That is the working method behind our Commercial Locksmith service.
Master Key System
Signs you need it
Your Lexington office has multiple locked doors and you’re juggling a ring of separate keys, with no way to revoke a single employee’s access.
What it costs in Lexington
Master key systems in Lexington are surveyed and quoted by written scope, typically $25-$45 per cylinder plus the cost of cylinders and labor.
How we do it
We map every door, assign key levels by role, pin each cylinder to the agreed hierarchy, and deliver a written key chart that stays current as staff changes.
Panic Bar Installation
Signs you need it
Your Lexington commercial space has a rear or side exit that fails code inspection or does not open in a single push.
What it costs in Lexington
Panic bar installation in Lexington typically runs $400-$900 per door, plus the cost of the bar itself, written in a flat quote before work begins.
How we do it
We mount the bar to manufacturer spec, adjust the latch for a clean strike, and verify that the door opens with one push from the inside under full occupancy.
What Commercial Locksmith Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Master key system (per cylinder) | $25-$45 plus hardware |
| Panic bar installation (per door) | $400-$900 plus hardware |
| Commercial rekey (per cylinder) | $18-$30 plus labor |
Can you rekey a Lexington office without disrupting business hours?
Yes. Commercial rekeys in Lexington can be done early morning or evening, and we key the new cylinders ahead of time so the actual door work is measured in minutes. Call (331) 310-8471 to schedule a written-scope quote.
Do you carry high-security commercial cylinder brands?
We are factory-authorized for Medeco, Mul-T-Lock, and Abloy, which matters for Lexington businesses that need restricted keyways and patent-protected key control. The spec and price go in writing before installation.
Automotive Locksmith in Lexington
Automotive locksmith work in Lexington peaks in January and February, when key fobs die in the cold and keys frozen inside cars are a daily occurrence. Modern vehicles with transponder keys and onboard immobilizers need a technician with programming equipment, not just a slim jim. We carry the diagnostic and cutting tools to replace keys on site and program them to the vehicle, and the price is fixed on the phone before we mobilize. That is the standard for our Automotive Locksmith crew.
Car Key Replacement
Signs you need it
You’ve lost the last working key to your car and you’re stranded in a Lexington driveway or parking lot.
What it costs in Lexington
Basic car key replacement in Lexington typically runs $100-$200, while transponder key replacement with programming runs $140-$280.
How we do it
We cut the key to the vehicle’s code, program the transponder chip to the immobilizer, and verify both the mechanical turn and the electronic start.
Car Lockout
Signs you need it
Your keys are on the seat or in the ignition, the doors are locked, and the temperature is dropping.
What it costs in Lexington
Car lockout service in Lexington typically runs $60-$120, with the rate fixed on the phone before dispatch.
How we do it
A technician opens the door without damaging the lock, confirms ownership, and can cut a new key on site if the original is cracked or worn.
Key Fob Programming
Signs you need it
Your fob no longer unlocks the doors or starts the car, even with a fresh battery, or you bought a replacement fob online.
What it costs in Lexington
Key fob programming in Lexington typically runs $70-$130 per fob when supplied with a physical key, plus key cutting if applicable.
How we do it
We connect to the vehicle computer, register the fob to the immobilizer, and test lock, unlock, trunk, and panic functions before leaving.
What Automotive Locksmith Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Car lockout | $60-$120 |
| Basic car key replacement | $100-$200 |

Can you program a transponder key at the car, or do I need a dealer?
Most transponder keys can be cut and programmed at the vehicle in Lexington, with no tow or dealer visit required. We carry the programming equipment in the van and confirm the price on the phone first.
What if my key fob fails in a Lexington driveway in winter?
We come to the driveway, diagnose whether the issue is the fob, the battery, or the vehicle receiver, and replace or program the fob on site. Call (331) 310-8471 and the quote is finalized before we leave the shop.

We are factory-authorized for Medeco, Mul-T-Lock, Abloy, Baldwin, and Schlage, and we stock common parts for those lines in our Lexington service vehicles.

Two things push locksmith prices higher in Lexington: the age of the hardware and the season. A 1960s Kwikset cylinder that has seized up takes longer to extract than a modern unit, and a January lockout on an iced-over keyway carries a higher rate than a mild-weather call in May. Whatever the figure, it is set in writing before anyone drives to your door. The dispatcher who answers the phone quotes the price, and the technician is not permitted to change it on site.
