Fast, Reliable Lock Installation & Rekey Across Manchester
Lock installation and rekeying in Manchester, NH typically runs $65-$185 per lock, depending on whether you need a standard cylinder rekey or full hardware replacement on century-old mill-era doors. We quote a firm price on the phone before any technician is dispatched, and that is the price on the invoice. No arrival surcharge, no pressure at the door. Call (331) 310-8471 and a live person answers.
Manchester is not a generic suburb. It is an old mill city where the housing stock was built before standardized lock cylinders existed. That means a rekey here often involves obsolete mortise locksets, skeleton-key hardware, and door frames that have moved a quarter inch out of square since the Coolidge administration. Our Lock Installation & Rekey team works this city every week. We know what lives behind those original brass plates on the West Side and in the South End.
Why Novak Lock & Security Is Manchester’s Preferred Lock Installation & Rekey Company
Daniel Novak founded this company in 2002 on a rule that still governs every call: the price is put in writing before anyone gets in a van, and the technician is contractually prohibited from changing it at the door. That is Haven Standard Clause 1, and it exists because the locksmith trade has a well-documented problem with bait pricing. We would rather lose a call than lose your trust.
Manchester homeowners call us for three reasons. First, our dispatchers quote real numbers on the phone, not “as low as” teasers. Second, every technician is background-checked and uniformed, and every job ends with a documented photo record left with the customer. Third, when a lock on an 1890s triple-decker has seized in a February freeze, we have probably already fixed the same failure two streets over that week. That is not marketing. That is the nature of working a dense mill city. The Manchester calls we run follow predictable patterns, and pattern recognition is what makes a technician fast and accurate.
Our Lock Installation & Rekey Services in Manchester

Smart Lock Installation
We install smart locks on doors that were never designed for them, which is the real test in Manchester. A 1910 South End four-square has a thicker door slab than a 2005 suburban colonial, and the mortise cavity may not align with a modern deadbolt prep. We arrive with extended tailpieces, reinforced strike hardware, and the knowledge of which retrofit kits actually hold on century-old wood. You get keypad access without telling every tenant in the building to stop slamming the door.

Keyless Entry
Keyless entry makes the most sense in Manchester’s multi-tenant housing, where physical keys multiply with every lease turnover and every copy cut at a hardware store. A landlord on the West Side with a triple-decker does not need six key copies floating around. We install keyless systems with audit trails, temporary codes for maintenance staff, and deadbolt-grade security that a former tenant cannot bypass with a $3 copy. Every code is manageable from a phone or a keypad, and every install is priced in writing before we start.

Keypad Lock
Keypad locks are the workhorse of Manchester rental properties, but not every keypad survives a New Hampshire winter on an exterior door. Freeze-thaw cycling puts moisture into the latch assembly, and a keypad that works fine in October can refuse codes in January. We install cold-rated keypad locks from Schlage and Baldwin, and we mount them on realigned strikes so the deadbolt is not fighting a shifted door frame. If your existing keypad has failed, we will tell you honestly whether it is the lock, the door frame, or the wiring, and we will quote the fix before we touch anything.

Biometric Lock
Biometric locks are still a specialty product, and Manchester is not a market where we recommend them casually. They work best on protected entryways, interior doors, or controlled-access spaces where weather is not a variable. For millyard condo owners who want fingerprint access on a common door, we install models with a mechanical key override and cold-weather firmware. For a rental unit door exposed to Granite Street weather, we will usually steer you to a keypad or smart lock instead. That is the honest recommendation, because we have seen biometric sensors fail in single-digit temperatures, and we do not install things we would not put on our own doors.

Trusted Brands We Service in Manchester
We install and service Baldwin, Mul-T-Lock, Sargent, and Abloy hardware across Manchester, and we stock common parts for those lines so we are not waiting on a distributor when your mortise cylinder needs a new tailpiece. Mul-T-Lock and Abloy are high-security systems with restricted keyways, which matters in a city where a copied key can compromise an entire building. Sargent mortise locks appear constantly in Manchester’s older institutional and commercial conversions. We are factory-authorized on these brands, and a factory-authorized tech is the difference between a rekey that works and a cylinder that gets drilled out and replaced unnecessarily.
Common Lock Installation & Rekey Problems We See in Manchester Homes

- Seized mortise cylinders in winter. Hard freeze-thaw cycles force moisture into century-old mortise locks, and the cylinder seizes solid. Tenants get locked out in January, and a landlord who forces the key snaps it off in the door.
- Deadbolts binding against shifted strike plates. The original wood frames in West Side and millyard-adjacent buildings have settled for 100-plus years. A fresh rekey will not fix a deadbolt that hits the strike plate a quarter inch off. We realign or replace the strike as part of the job, because a lock that does not seat is not secure.
- Worn-out pin and tumbler cylinders from repeated rekeys. In high-turnover rental stock, a landlord-supplied lock may have been rekeyed a dozen times across rotating tenants. The cylinder wears so loose that standard picks and tension tools slip. At that point, non-destructive entry means impressioning, and the durable fix is a new cylinder or a restricted key system.
- Steel utility doors on converted millyard buildings. Those heavy industrial doors along the Merrimack have commercial multi-point locking systems that were never meant to be serviced as residential hardware. Losing the key is not a simple cylinder swap. We handle those without drilling steel, and we quote the full scope in writing before any work begins.
Pricing for Lock Installation & Rekey in Manchester, NH
Here is what we quote for Manchester work, in real dollar ranges. A standard lock rekey runs $65-$95 per cylinder, which includes new keys and a documented photo record of the completed work. Smart lock installation runs $185-$385 depending on the make and whether the existing prep needs modification, which it often does on pre-1930 doors. Keypad lock installation runs $150-$290. Biometric lock installation runs $220-$420 when we recommend it at all. Full mortise lockset replacement on a century-old door runs $250-$550, and yes, that is higher than a modern deadbolt because obsolete mortise bodies are not cheap and the door prep is labor-intensive.
The price you get on the phone is the price on the invoice. That is Haven Standard Clause 1 and it has been the rule since 2002. No arrival surcharge, no upcharge at the door, no “your lock is worse than we thought” renegotiation. Call (331) 310-8471 for a quote. Free estimates, no obligation.

FAQs - Lock Installation & Rekey in Manchester

Yes. We remove the broken key fragment from the mortise lock body, then either rekey the existing lock or replace the cylinder with a modern pin-tumbler insert that fits the original mortise cavity. We do this regularly on Amoskeag mill-era housing where the original lock body is part of the door’s structure. You keep the door. You lose the skeleton key vulnerability. Call (331) 310-8471 and we will quote the full job in writing before dispatch.
Yes, rekeying is legal. What is not legal is a landlord lockout: NH RSA 540 is explicit that a landlord cannot remove a tenant’s access without a court order. We understand that statute cold, and we will not perform a lockout. What we will do is rekey or replace the lock between tenancies, in a vacant unit, with a written scope and a photo record. That is standard turnover work for Manchester landlords. Call (331) 310-8471 and we will quote it.
It is usually a cold-weather lock problem. Multi-point locking systems on those converted industrial doors have tight tolerances, and when temperatures drop below 0°F, the latch mechanism contracts and the electronics can lag or fail to register the code. The fix may be a cold-rated keypad, a realigned strike, or a replacement latch assembly. We diagnose it on site and quote the repair before we start. Call (331) 310-8471.
Yes. We replace the worn Kwikset cylinder with a bump-resistant high-security cylinder, typically Schlage or Mul-T-Lock, and we key it to a restricted keyway so the hardware store down the street cannot copy it. You get a key control card and only the people you authorize can duplicate keys. That is the standard fix for a high-turnover Manchester rental where old keys are still in circulation. Call (331) 310-8471 for a written quote.
Yes. We install new cylinders into the existing multi-point lock bodies, or we fit new lock bodies into the original steel door prep, without drilling new holes. Those doors were manufactured to a commercial standard, and we have the factory parts and tooling to work within the existing prep. This is a job most suburban locksmiths will not touch without drilling, which is why Manchester’s millyard conversions are our specialty. Call (331) 310-8471 and we will quote it in writing before anyone arrives.
