Weymouth sits on 38 miles of coastline along the Back River and Weymouth Fore River, and that salt-laden air is not kind to exterior hardware. The same water views that drew families here in the 1950s and 1960s are now corroding the original locksets on those homes. Meanwhile, the Union Point development on the old South Weymouth Naval Air Station land represents an entirely different era of construction, with keyless entry and smart lock installs now routine. No other town on the South Shore presents this particular split: aging, salt-weakened legacy hardware in one neighborhood, brand-new construction demanding electronic access in another, sometimes five minutes apart. That dual challenge is exactly why Weymouth homeowners need a locksmith who understands both worlds.
Why Strongbox Lock & Safe Co. Is Weymouth’s Preferred Lock Installation & Rekey Company
We’ve served communities across the South Shore for over 42 years, and Weymouth has always been central to our route. Our technicians know the difference between a North Weymouth Cape Cod with original 1950s door hardware and a Union Point townhouse built in 2020, and we stock parts and equipment for both. The price we quote on the phone is the price on the invoice. No bait, no switch, no “trip charge” that balloons once we’re at your door.
Our background-checked, uniformed technicians present ID at every Weymouth home. The 90-Day Done Right Promise backs every job in writing: if something isn’t right, we come back, no paperwork, no arguing. Calls are answered by a live person around the clock, including nights, weekends, and holidays, because a lock that won’t turn on a Sunday evening in East Weymouth is still a problem that needs solving.
We also honor a permanent 5% discount for seniors and veterans in Weymouth, and we offer a free second opinion on any written estimate you’ve received from another locksmith. Our $89 Seasonal Tune-Up catches salt corrosion and frame swelling before they strand you outside.
Our Lock Installation & Rekey Services in Weymouth
Smart Lock Installation
Smart lock installation in Weymouth runs $220-$450 depending on the hardware and whether we’re retrofitting an older door or working with new construction. At Union Point, where many homes were built with smart-ready prep, installs tend toward the lower end of that range. In North Weymouth or East Weymouth, where we’re often removing a corroded original lockset and filling old mortise pockets, the job takes more time. We install Schlage Encode, Yale Assure, and Kwikset Halo systems, and we’ll walk you through the app setup before we leave. You get the 90-Day Done Right Promise on the installation and the hardware.

Keyless Entry
Keyless entry systems for Weymouth homes typically cost $180-$390 installed, with push-button mechanical models at the lower end and electronic keypad deadbolts at the higher end. For the ranch homes off Route 3A with original hardware, a keyless entry upgrade often means replacing a worn Kwikset or Schlage that hasn’t turned smoothly in years. The salt air near the Fore River is particularly hard on the springs and tumblers in mechanical push-button locks, so we specify marine-grade finishes for coastal Weymouth properties. We’ll tell you on the phone whether your door needs additional strike plate work, and we’ll include that in the flat quote.

Keypad Lock
Keypad lock installation in Weymouth generally falls between $190 and $420. We see strong demand for these in two very different neighborhoods: the multi-generational Cape Cods near Great Esker Park, where adult children want parents to stop hiding keys under planters, and the newer homes near SouthField, where keypad entry is expected standard. We stock Baldwin and Schlage keypad deadbolts with local parts availability, so most Weymouth installs happen same-day or next-day. If your door frame has swollen from freeze-thaw cycling, we’ll realign the strike as part of the job, not as an add-on.

Biometric Lock
Biometric lock installation in Weymouth starts around $280 and can reach $550 for fingerprint-enabled deadbolts with full smart-home integration. These are less common in the town’s older housing stock but increasingly requested in Union Point and for home offices in South Weymouth. We install Medeco and Abloy biometric systems with ANSI Grade 1 ratings. The fingerprint sensors we specify are rated for Massachusetts humidity and temperature swings, which matters more than most homeowners realize until a cheap sensor fails in a damp coastal winter.

Electronic Lock
Electronic lock installation and repair in Weymouth runs $160-$440. We service everything from basic battery-powered latches to hardwired access control systems. Many of the 1960s-era ranches near Jackson Square have had multiple generations of electronic locks installed by previous owners, often poorly. We remove the old mounting holes, reinforce the door if needed, and install new hardware that actually fits. Our flat pricing includes this prep work; we don’t arrive and then discover “unexpected complications.”

Key Duplication
Key duplication for Weymouth residents is $8-$25 per key depending on the blank type, with high-security Medeco or Mul-T-Lock keys at the higher end. We cut keys on-site for most standard residential locks, and we can duplicate restricted-keyway blanks for systems we’ve installed. If you’re rekeying a home in Weymouth after a purchase or tenant change, we’ll cut as many new keys as you need while we’re there.

Trusted Brands We Service in Weymouth
We install and service Schlage, Medeco, Kwikset, Abloy, Baldwin, Yale, Mul-T-Lock, and Sargent throughout Weymouth, with local parts stock for the brands we see most often in this market. Schlage and Kwikset dominate the town’s older residential stock; Medeco and Mul-T-Lock appear more frequently in commercial applications along Route 18 and in the medical offices near South Shore Hospital. For Union Point new construction, we spec Baldwin and Yale smart hardware that matches the finish packages specified by most builders in that community. Because we carry inventory locally, a Weymouth customer calling about a failed lock on a Tuesday morning typically has a working door by Tuesday afternoon. No waiting for a distributor in Boston to ship.
Common Lock Installation & Rekey Problems We See in Weymouth Homes
- Salt-air corrosion seizes cylinders on coastal homes. The Back River and Weymouth Fore River expose waterfront-adjacent neighborhoods to salt-laden air that corrodes exterior lock cylinders and deadbolt hardware far faster than conditions just a few miles inland in Braintree or Holbrook. We replace rather than rekey these locks; the internal pinning is usually too damaged to salvage.
- Freeze-thaw cycles swell wooden door frames on older Cape Cods. Every late fall and early spring, Weymouth sees a predictable spike in deadbolt binding as moisture in wooden frames expands and contracts. The fix is strike realignment, not a new lock, and we include this diagnosis in our $89 Seasonal Tune-Up.
- Original 1950s locksets are no longer rekeyable. The postwar Cape Cods and ranches built during Weymouth’s suburban boom carry locksets with worn, obsolete pinning that no blank matches. We explain this on the phone when you describe the hardware, quote a replacement flat, and install modern Grade 2 or Grade 3 hardware that will last.
- Smart-lock installs on older doors need structural prep. A Union Point install might take 45 minutes. The same smart lock on a 1954 Cape Cod in North Weymouth often requires filling old mortise pockets, reinforcing the door edge, and sometimes replacing the entire door prep. We quote this honestly upfront, not after we’ve started.

FAQs - Lock Installation & Rekey in Weymouth
Salt-laden air off the Weymouth Fore River accelerates corrosion in lock cylinders and deadbolt mechanisms far more aggressively than in inland locations. The salt crystals attract moisture, which then freezes in winter, expanding and jamming the internal components. We typically replace rather than repair these locks, specifying marine-grade finishes for coastal Weymouth homes. Call (877) 664-8139 and we’ll quote a replacement flat over the phone.
Many original Schlage locksets from Weymouth’s postwar building boom have worn pinning or obsolete keyways that no longer match available blanks. If the cylinder is salvageable, we’ll rekey it for $25-$45. If the internal components are too worn, we’ll quote a replacement with modern Grade 2 hardware that fits your door’s existing prep. We’ll know which situation applies when you describe the lock or text a photo. Estimates are free, call (877) 664-8139.
We typically recommend Schlage Encode Plus or Yale Assure Lock SL for Union Point homes, as both integrate cleanly with the Wi-Fi infrastructure and smart-home prep standard in that development. These install in under an hour on a properly prepped door and carry the 90-Day Done Right Promise. Call (877) 664-8139 to schedule, and we’ll confirm your door prep over the phone.
Freeze-thaw cycling in Weymouth’s wooden door frames, particularly on the town’s aging Cape Cods, causes the wood to expand and contract, misaligning the strike plate relative to the deadbolt. This is a seasonal, predictable issue in this climate, not a lock failure. Our $89 Seasonal Tune-Up includes strike realignment and lubrication with weather-resistant graphite. Call (877) 664-8139 to schedule before the next seasonal swing.
Yes. Our Weymouth technicians move between both housing types daily, carrying parts for 1950s-era mortise locks and the latest smart-lock systems on the same truck. In North Weymouth near the Fore River, we replaced a frozen, salt-corroded Schlage mortise lock on a 1954 Cape Cod with a new Baldwin keypad deadbolt, upgrading security and eliminating annual freeze-up calls. Whether your home is 70 years old or 7 months old, we quote flat and stand behind the work. Call (877) 664-8139.
