Residential Locksmith in Lexington, MA
Residential locksmith service in Lexington typically runs $89-$450 depending on the job, with most lockouts resolved in under 30 minutes and rekeys completed same-day. We’re Strongbox Lock & Safe Co., and our technicians know the swollen colonial doorframes along Massachusetts Avenue, the detached garages that freeze in nor’easters, and the antique mortise cases that still turn in homes near the Battle Green. Call (877) 664-8139 and a live person answers, 24/7, including holidays.
Why Lexington Homes Are Different
Lexington’s dual market is unlike any neighboring suburb. The historic district around the Battle Green holds genuine 18th- and 19th-century colonials where preservation-minded owners demand period-appropriate mortise lock service, while surrounding affluent neighborhoods off Route 128 drive demand for Grade-1 high-security cylinders and smart lock integration at price points well above regional norms. A locksmith here must serve both ends of that spectrum within the same ZIP code. The freeze-thaw cycle hits harder than most expect: every November and March, we field calls from 02420 and 02421 about deadbolts that suddenly bind as wood-frame doors swell and shift.
Residential Locksmith in Lexington
In Lexington’s older colonials, we regularly rekey antique mortise locks to accept modern Schlage or Kwikset keys while preserving original hardware - a specialty most shops skip. Our background-checked, uniformed technicians show ID at every door, and we quote a flat price on the phone before the truck rolls. Residential Locksmith services cover everything from standard lockouts to complex historic restoration.
Lock Rekey
A lock rekey in Lexington costs $89-$175 for most residential cylinders and is our most common call. We re-pin the existing lock so old keys no longer work - faster than replacement, same security. If you’ve bought a home near the Battle Green or had a tenant move out on Marrett Road, rekeying lets you carry one key for every door without replacing hardware that matches your home’s character.
Deadbolt Installation
Deadbolt installation in Lexington runs $140-$320 depending on door material and whether we’re retrofitting a pre-Revolutionary wood frame or a modern steel entry. Wood-frame doors swell in late fall, contract in dry winter air, and the bolt that threw smoothly in September starts binding by November. We see this constantly on homes along Waltham Street. We install weather-resistant cylinders and check door alignment, not just the lock.
Can you rekey my antique mortise lock to work with modern keys?
Yes. We regularly rekey antique mortise locks in Lexington to accept modern Schlage or Kwikset keys while preserving the original case and faceplate. We recently restored a circa-1850 mortise lock on a Hancock Street colonial near the Battle Green, rebuilding the internals after a broken spring and worn tumblers threatened the homeowner’s period authenticity. Call (877) 664-8139 for an exact quote - estimates are free.
Commercial Locksmith in Lexington
Commercial locksmith service in Lexington typically runs $180-$650 depending on the job, with technicians usually arriving within 30-45 minutes for lockout calls. We serve historic storefronts along Massachusetts Avenue near the Battle Green and professional offices near Route 128, where biotech and tech firms need key control and audit trails their insurers require. Commercial Locksmith work demands flat pricing and documented access - we deliver both.
Master Key Systems
Lexington’s multi-tenant professional buildings on Hartwell Avenue and estate properties with carriage houses benefit from master key systems that balance access with control. A typical system for a small commercial building runs $450-$1,200 depending on cylinder count and keyway complexity. We design these with expansion in mind, using Schlage or Medeco keyways with patented control to prevent unauthorized duplication.
High-Security Lock Installation
Lexington’s Route 128 corridor houses biotech, tech, and professional services firms that demand more than standard hardware. We install Medeco and Schlage Primus high-security cylinders at $280-$550 per door installed, including rekeying. These resist picking, drilling, and unauthorized key duplication - critical for facilities handling sensitive data or controlled substances.
Do you offer master key systems for Lexington commercial buildings?
Yes. We design and install master key systems for multi-tenant commercial buildings, estate properties with outbuildings, and professional offices throughout Lexington. A typical system for a small commercial building runs $450-$1,200, larger properties scale from there. We document every access level so changes are straightforward later. Call (877) 664-8139 to schedule a site evaluation - estimates are free.

Locked out at the Lexington Depot commuter lot? Need a replacement key for the Tesla in your driveway off Route 2A? Most automotive calls in Lexington resolve same day, often within the hour. We answer every call to (877) 664-8139 with a live person, 24/7, and we know the narrow colonial driveways and tight carriage-house garages that complicate access. Automotive Locksmith service covers everything from standard unlocks to vintage ignition rebuilds.
Car Key Replacement
Lost your only key at Minuteman Bikeway? We cut and program replacement keys on-site for most makes and models. In Lexington’s tech-executive neighborhoods off Marrett Road and Waltham Street, we regularly replace keys for BMW, Mercedes, Audi, and Tesla vehicles where dealership pricing runs 40-60% higher and waits stretch two weeks.

Lock Installation & Rekey in Lexington
Lock installation and rekeying in Lexington typically runs $140-$380 for standard residential work, with same-day scheduling throughout 02420 and 02421. Our technicians cover the full span: pre-Revolutionary colonials ringing the Battle Green, mid-century ranches off Marrett Road, newer custom builds near Route 128. Lock Installation & Rekey work starts with a flat price on the phone - no bait, no switch, no surprises.
Smart Lock Installation
Many historic door frames in 02420 lack structural integrity for modern smart lock bolt mechanisms without reinforcement. We assess the door’s actual condition and specify Schlage Encode or Yale Assure models that fit properly. Smart lock installation in Lexington runs $280-$520, including frame reinforcement when needed. For homes near Route 128 where executives want remote access logging, we configure integration with whole-home systems.
Keyless Entry
Keyless entry systems eliminate the daily key hunt while maintaining security standards that satisfy Lexington insurance underwriters. We install keypad and touchscreen systems on front doors, side entrances, and detached garages throughout 02421. For mid-century ranches off Marrett Road, we often replace original Kwikset knob-sets with keyless levers that accommodate aging hands. Keyless entry installation typically costs $220-$440.
Do you offer smart lock installation that works with historic door hardware?
Yes. We install smart locks that integrate with historic hardware by fabricating custom adapter plates and reinforcing door frames without visible modification to original trim. Most Lexington historic districts permit interior electronic components even when exterior appearance must remain unchanged. We assess your specific door during a free estimate and specify Schlage or Yale platforms that accommodate your constraints. Call (877) 664-8139 to schedule.
Emergency Locksmith in Lexington

We’ll quote your flat price, dispatch the nearest technician, and text you an ETA. Most Lexington lockouts resolve in under 20 minutes on site.
Broken Key Extraction
Lexington’s freeze-thaw cycle is hard on keys and locks alike. We extract broken keys from antique mortise locks where original brass has crystallized with age, and from modern deadbolts where thermal expansion has stressed the metal. Our technicians carry precision extractors and cut replacement keys on the truck. Typical broken key extraction runs $95-$150.
Do you provide emergency lockout service for detached garages with frozen cylinders?
Yes. We carry cylinder defrosting tools and can open frozen locks without drilling. Exterior cylinders in unheated mudrooms and detached garages are particularly prone to moisture infiltration and cylinder freeze during nor’easters. We also install weather-resistant replacement cylinders to prevent recurrence. Call (877) 664-8139 - we answer 24/7.
