Fast, Reliable Lock Installation & Rekey Across Weymouth
Lock installation and rekeying in Weymouth runs between $95 and $260 for standard deadbolts and knobs, with smart lock installation starting around $185. We quote the full price on the phone before anyone gets in the van, and that price does not change when the technician arrives. Haven Standard Clause 1: the price on the phone is the price on the invoice. Call (331) 310-8471 and a live person answers, day or night.
Weymouth isn’t one housing market. It’s North Weymouth capes with salt-crusted cylinders, Weymouth Landing colonials with original mortise locks from the 1930s, and newer Union Point construction with electronic access requirements. We know the difference because we work all of it. When you call for lock installation or rekeying, you get a technician who has already worked your street, your lock type, and your coastal exposure.
Why Novak Lock & Security Is Weymouth’s Preferred Lock Installation & Rekey Company
We’re the locksmith that puts a written price in your hand before a single tool comes out of the case. That rule has held since 2002, and it applies to every rekey, every smart lock install, every emergency callout in Weymouth. Background-checked, uniformed technicians arrive in a marked van, complete the work, and leave you with a documented photo record of exactly what was done.
Weymouth homeowners call us because we don’t guess at old hardware. A 1940s colonial in North Weymouth with a seized mortise lock needs a different approach than a 2019 condo in Union Point with a Schlage electronic deadbolt. We diagnose first, explain the options in plain terms, and let you decide. No pressure. Every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right.
Daniel Novak founded this company on a simple observation: people don’t actually mind paying for locksmith work. They mind being quoted one number and charged another. So we removed that possibility entirely. The dispatcher quotes a firm price. The technician is contractually prohibited from changing it at the door. That’s the whole model, and it’s held for over two decades.
Our Lock Installation & Rekey Services in Weymouth
Smart Lock Installation
Smart lock installation in Weymouth typically runs $185 to $340 for most major brands, including Yale and Baldwin models. The catch in this town is door alignment. Many Weymouth homes have settled over decades, and the original door frames are no longer plumb. A smart lock with a motorized bolt will fail to throw completely if the strike plate isn’t corrected for that warp. We don’t just swap the hardware. We check the frame, realign the strike, and test the lock at least five full cycles before we call the job done.
Keyless Entry and Keypad Locks
Keyless entry lock installation in Weymouth runs $160 to $290 for a quality keypad deadbolt. These are popular with homeowners around Weymouth Landing and East Weymouth who manage rentals, vacationers, or just don’t want to hand out keys anymore. The coastal consideration here is battery compartment corrosion. Salt air gets into the battery housing on entry-level keypads and eats the contacts within two or three years. We recommend and install models with sealed battery compartments and marine-grade contacts for harbor-facing properties.
Biometric Lock Installation
Biometric lock installation in Weymouth runs $240 to $420, and it’s a growing segment for homeowners around Union Point and the newer construction near the old South Weymouth Naval Air Station. These locks read fingerprints and don’t care about salt air or frozen cylinders the way mechanical locks do. The installation is more involved: the reader needs to sit level against the door surface, the bolt needs to align cleanly, and the software has to be paired before we leave. We do all of that on site and walk you through the enrollment process.
Key Duplication
Key duplication in Weymouth is a same-day job, usually $3 to $9 for standard keys and $15 to $45 for restricted or high-security blanks like Medeco or Mul-T-Lock. One thing to know: if you’re copying a key that says “Do Not Duplicate,” we can’t cut it without proof that you own the lock or property. That’s not us being difficult. It’s about keeping an unauthorized copy out of circulation. Bring documentation, and we’re happy to help.

Trusted Brands We Service in Weymouth
We install, service, and rekey Medeco, Yale, Baldwin, and Mul-T-Lock hardware across Weymouth. Medeco and Mul-T-Lock are high-security cylinders that cannot be picked or bumped by standard tools, and they’re a smart upgrade for Weymouth homes with original builder-grade hardware. Baldwin locks are popular on Weymouth colonials where homeowners want solid brass construction that actually holds up to salt air better than zinc-alloy hardware. We keep common replacement cylinders and strike plates stocked for these brands, which means many Weymouth rekey jobs go from phone call to finished in under two hours.
Common Lock Installation & Rekey Problems We See in Weymouth Homes
- Salt-air corrosion on harbor-facing locks. North Weymouth properties near Hingham Bay and the Fore River get hit hard. Deadbolt cylinders that should last 30 years are seized solid by year 10. The pins inside the cylinder pit and bind, and a standard rekey without corrosion treatment fails within weeks because the salt residue keeps working on the new pins.
- Mortise locks in pre-WWII housing stock. The capes and colonials concentrated around Weymouth Landing, North Weymouth, and East Weymouth were built when mortise locks were the standard. These are not the bored cylindrical locks you buy at a home center. The lock body sits in a rectangular pocket mortised into the door edge, and fitting a modern replacement often requires chiseling, custom fitting, and specialty parts. Some can be rekeyed in place. Some genuinely need to be replaced. We’ll tell you which and show you why.
- Warped original doors that break new smart locks. Weymouth’s older homes settle. Doors twist. A smart lock on a warped door will bind against the strike plate and refuse to throw the bolt fully. The lock isn’t defective; the door needs the strike plate repositioned to match the out-of-plumb frame. We correct this on nearly every smart lock install we do on Weymouth’s older stock.
- Freeze-thaw cycles seizing already-corroded pins. The New England winter does something specific to Weymouth: moisture from the salt air gets into the cylinder, the temperature drops below freezing, and the corroded pins expand and lock solid. A lock that worked fine in October can be completely seized by February. We carry penetrating lubricant and replacement cylinders on every winter call, because this town produces this failure mode more consistently than Braintree or Brockton ever will.

FAQs - Lock Installation & Rekey in Weymouth
Can my old mortise lock in a Weymouth colonial be rekeyed, or does it need to be replaced?
Most Weymouth mortise locks can be rekeyed in place, provided the lock body isn’t corroded through and the internal springs still have tension. We disassemble the cylinder, clean the pin chambers, install new pins to match a new key, and reassemble. If the original lock body is pitted beyond repair or the cylinder housing is cracked from years of salt-air stress, replacement is the honest call. We’ll show you the damage before we recommend either path.
Why does my deadbolt seize every winter on my North Weymouth street, but my friend in Braintree never has this problem?
North Weymouth is a peninsula surrounded on three sides by Boston Harbor tidal water. The salt-laden air off Hingham Bay and the Back River deposits corrosive residue inside your lock cylinder over the summer and fall. When winter hits, the freeze-thaw cycle pushes that moisture deeper and the corroded pins seize solid. Braintree is inland enough that this process simply doesn’t happen at the same intensity. The fix is corrosion-focused maintenance: clean, re-lubricate, and replace the cylinder internals before winter starts.
How do I know if my lock is corroded enough to need replacement instead of just a rekey?
Three signs say replacement: visible pitting or green oxidation on the cylinder face, a key that needs to be wiggled and forced to turn, or a deadbolt that fails to throw fully even after the door is aligned. If we disassemble a lock and find the pin chambers are scored beyond reaming, rekeying won’t hold. We’ll tell you on the spot, and the price for replacement will already be in writing from the phone call.
Can you install a smart lock on my original Weymouth door that has warped over the years?
Yes, but only if the strike plate is repositioned to match the door’s actual alignment. Warped doors are common across Weymouth’s pre-WWII stock, and a smart lock’s motorized deadbolt has less tolerance for misalignment than a manual throw. We correct the strike plate, sometimes add a reinforced plate to give the bolt a clean pocket, and test the lock repeatedly before we leave. If the door is too far gone, we’ll say so and recommend the most cost-effective fix rather than selling you a lock that will jam.
What’s the difference between rekeying and changing my lock, and which is better for coastal Weymouth homes?
Rekeying replaces the pins inside your existing lock so the old key no longer works. Changing the lock replaces the entire hardware assembly: cylinder, housing, bolt, trim, everything. For Weymouth homes with sound original hardware, rekeying is usually the better value because you keep solid brass mortise lock bodies that are better built than most modern replacements. For locks that are ten-plus years old on harbor-facing doors, replacement is often the better call because the cylinder has absorbed too much salt-air damage. We’ll assess the actual condition and quote both options in writing before any work begins.
