Fast, Reliable Lock Installation & Rekey Across Lynn
Lock installation and rekeying in Lynn, MA typically runs $85-$165 for a standard cylinder rekey and $120-$320 for a new deadbolt install, and most jobs are quoted in writing before a technician is dispatched. We know Lynn’s housing stock because we work in it every week: triple-deckers off Boston Street, converted Victorians near Flax Pond, and rowhouses along the harbor where salt air does real damage to door hardware. When you call (331) 310-8471, a live person answers and gives you a firm price before anyone gets in a van. That’s how we’ve operated since 2002, and it’s the only way we work.
Why Novak Lock & Security Is Lynn’s Preferred Lock Installation & Rekey Company
We’re not the newest name in Lynn, and we don’t pretend to be. What we are is a locksmith shop that writes down the price before the work starts and photographs the job when it’s done. That matters in a city where a lot of the work is between a landlord and a departing tenant, two people who rarely agree on anything except that they want the lock changed correctly and for the price that was quoted. Our Lock Installation & Rekey team works on the housing Lynn actually has: triple-deckers with original mortise locks, apartment buildings with multiple points of entry, and condos where the association rules restrict what hardware you can install. Daniel Novak built the company around a single rule: the price on the phone is the price on the invoice. We don’t call it a guarantee. We call it Haven Standard Clause 1.
That principle carries through to the work itself. Every job ends with a documented photo record left with the customer. Every technician is background-checked and uniformed. And every lock installation or rekey is covered by our 365-Day Done Right Promise: if it’s not right, we make it right. In Lynn, where a seized deadbolt on a January night isn’t a minor annoyance, that promise has teeth.
Our Lock Installation & Rekey Services in Lynn
Smart Lock Installation
Installing a smart lock on a hundred-year-old Lynn door usually means more than drilling a new hole. The original mortise prep is often too large or too worn for a modern deadbolt, and without a retrofit plate the deadbolt throw binds against the strike plate. We install smart locks on Lynn’s older doors with the right adapter hardware, then verify the alignment before we leave. Most smart lock installs in Lynn run $180-$380 including the retrofit work, quoted in writing first.
Keyless Entry
Keyless entry is the most common request we get from landlords in the Wyoma Square and West Lynn triple-decker corridors. A keypad at the building entry means a turnover no longer requires rekeying every cylinder; you just change the code. For tenants, it means not getting locked out when the bottom door key sticks. We install keyless entry systems on both single-family homes and multi-unit buildings, and we always walk the landlord through code management before we leave.
Keypad Lock
A keypad lock on an individual apartment door gives a tenant control over their own access without the landlord needing to cut new keys. We install keypad locks from Schlage, Yale, and Baldwin, and we stock the common finish colors Lynn customers ask for so we’re not ordering parts after the first visit. That matters when you need the work done the same week, not the same month.
Biometric Lock
Biometric locks are a smaller part of the market in Lynn, but they’re real. Condo owners in the downtown conversion buildings ask for fingerprint entry because it solves the problem of copied keys floating around the building. We carry Mul-T-Lock and Sargent biometric and electronic options, and we’ll give you an honest assessment of whether a fingerprint lock actually improves security in your specific entry, or whether a high-security cylinder does the job better for less money.

Trusted Brands We Service in Lynn
We’re factory-authorized on Baldwin, Mul-T-Lock, Sargent, and Yale hardware, and we work on everything from entry-grade Kwikset to high-security Medeco. For Lynn customers, that authorization means we can order exact-match parts for a Baldwin mortise lock from the 1920s, and we can key a Mul-T-Lock restricted system so no prior tenant’s key works in any cylinder in the building. We stock common deadbolts, strikes, and cylinders locally, and we tell customers up front whether a repair or a replacement is the better spend.
Common Lock Installation & Rekey Problems We See in Lynn Homes
- Loose cylinders from repeated rekeying. Lynn landlords rekey between every tenant, which is correct practice, but after a decade of pin changes the cylinder itself wears out. The plug twists, the key hangs up, and eventually it won’t turn at all. We replace the cylinder, not the whole lock, which saves money.
- Salt-corroded deadbolts on harbor-facing doors. Buildings along the Lynn Shore Drive and the waterfront streets take the brunt of the salt air. Exterior cylinders corrode from the inside, and when a freeze comes, moisture in the cylinder expands and seizes the deadbolt solid. This is a seasonal pattern we plan for every winter in Lynn.
- Misaligned strike plates from building settlement. Triple-deckers settle. It’s what they do. When the door frame shifts even an eighth of an inch, a deadbolt that used to throw cleanly now grinds against the strike plate. We realign the strike and, where needed, mortise a new one rather than tell you to replace the door.
- Smart locks installed on original mortise prep without a retrofit plate. We see this fairly often: a homeowner buys a smart lock, follows the generic instructions, and ends up with a deadbolt that sticks in the locked position. The fix is usually a retrofit plate and a proper strike adjustment. Nobody wants a lock that works when it feels like it.

FAQs - Lock Installation & Rekey in Lynn
Can you rekey the mortise locks in my Lynn triple-decker without replacing the original hardware?
Yes. We rekey original mortise locks regularly, and in most cases the original lock body and trim stay in place while we replace or repin the cylinder inside. That’s the right call on a pre-1930 Lynn building where the mortise lock is part of the original door. Rekeying a mortise cylinder in Lynn typically runs $85-$165 per cylinder. Call (331) 310-8471 and we’ll walk you through what your specific lock needs.
How often should a Lynn landlord rekey between tenants in a multi-family building?
Every time a tenant moves out. No exceptions. We tell landlords in Lynn this directly: a departing tenant’s key is a security liability until the lock is changed or rekeyed, and you cannot verify how many copies exist. In a triple-decker, rekey all exterior doors and the vacant unit’s door at turnover. For landlords juggling multiple units, we recommend a master key system so you have one key for the building and tenants have individual keys. The upfront cost is modest compared to rekeying every cylinder independently each time a unit turns over.
Why does my deadbolt seize up every winter near the water in Lynn?
Salt-laden air from the harbor corrodes the inside of exterior lock cylinders over time, and when New England’s freeze-thaw cycle hits, moisture trapped in that corrosion expands and locks the cylinder in place. The deadbolt won’t turn, and the key may break if forced. This is a known pattern in the waterfront sections of Lynn. The fix is usually a new cylinder and weatherproofing on the exposed hardware. If you’re near Lynn Shore Drive or the harbor side of West Lynn, plan to have your exterior cylinders inspected before the hard freeze arrives. Call (331) 310-8471 and we’ll get it done before the next cold snap.
Can you duplicate a key that says “Do Not Duplicate” for my Lynn apartment building?
If you own the building and can provide documented proof of ownership, yes. If you’re a tenant, no. We require written authorization from the property owner or building management before we cut a marked restricted key. For high-security keys like Mul-T-Lock or Sargent, the manufacturer controls key blanks, and we verify authorization through the registered system. That’s not a policy designed to be difficult; it’s the only way restricted keying works. If you manage a Lynn building and need duplicate keys for maintenance staff, call us and we’ll verify ownership and cut them same day in most cases.
Do you install keypad or smart locks on the old doors in Lynn’s converted Victorians?
Yes, and we do it often. The original doors on many of Lynn’s converted Victorians are solid wood with mortise locks, and a smart lock install on that prep requires a retrofit plate and a properly aligned strike. We carry the adapter hardware from Schlage, Baldwin, and Yale, and we install the lock so the deadbolt throws smoothly without binding. The job typically runs $180-$380 per door, quoted in writing before we start. If your door is particularly old or the frame has settled, we’ll tell you what’s needed and what it costs before any work begins.
