Lock Installation & Rekey in Woburn, MA: What It Costs and How It Works
Lock installation or rekeying in Woburn typically runs $85-$160 per cylinder for rekeying and $180-$420 for new lock installation, quoted in writing before we arrive. Most jobs are completed same-day, and because our dispatcher quotes the full price on the phone, the number on your invoice matches the number you approved. That rule has been in place since 2002 and it applies to every job we do in Woburn, from a single deadbolt on a West Side ranch to a full re-core at a Cummings Park office suite.

- Every price is written and firm before dispatch. No door-surprise upcharges, no bait-and-switch. Haven Standard Clause 1.

- Restricted keyways and master-key work for biotech and pharma tenants is a regular part of our week in Woburn, not an occasional specialty.
Why Woburn Calls Us for Lock Installation and Rekeying
Woburn is not a simple suburb. Between the triple-deckers and two-families around Woburn Center, the post-war Capes and ranches on the outer streets, and the dense commercial corridor along Route 128, a locksmith here has to handle three different kinds of work in a single day. That mix is exactly what we see. Daniel Novak founded the company in 2002, and the team that works Woburn is background-checked, uniformed, and trained on everything from a Schlage deadbolt to a Medeco restricted keyway.
Woburn residents tell us the same two things: they want a price before anyone gets in the van, and they want to know the person at the door is who they say they are. Both are settled before we arrive. The price is written and firm. The technician arrives in uniform with a company ID. We leave a documented photo record of the work with every customer. It is not an upsell. It is procedure.
Our Lock Installation & Rekey Services in Woburn
Smart Lock Installation in Woburn
Smart locks are the most common install request we get from Woburn homeowners, especially around neighborhoods like Rag Rock and Horn Pond where we see a lot of 1990s-era front doors being upgraded. The question is always whether the existing door prep matches the smart lock. Older Woburn doors with a small-diameter bore need a retrofit kit, and some mortise-lock doors need a full prep conversion. We install brands like Schlage Encode, Yale, and Baldwin smart locks, and we will tell you honestly if your existing door is a good candidate or a conversion job.
Keyless Entry and Keypad Lock Installation
Keyless entry gets called for most often on rental properties, condos, and the back doors of homes where homeowners are tired of carrying keys for the garage, the side entry, and the front. On Woburn triple-deckers, keypad locks give landlords a way to rotate access codes between tenants without handing out new keys. The hardware is straightforward, but the weatherproofing matters here more than it does on the coast. Woburn’s inland freeze-thaw cycles are harder on keypad batteries and external wiring, so we recommend models rated for sub-zero operation and we seal the battery compartments properly.
Key Duplication and Key Control
Standard key duplication in Woburn is the same as anywhere else, but key control is not. On a triple-decker, a tenant copies a Schlage key at a hardware store and now someone the landlord never met has a key to the building. That is why we spend more time in Woburn explaining restricted keyways and key-control systems than we do cutting single keys. If a key cannot be copied without an authorized signature, the building’s security does not depend on the honor system.
Commercial Re-Cores and Access Control for Cummings Park
Cummings Park along Route 128 is one of New England’s largest privately-owned office and R&D campuses, and its biotech and pharma tenants run master-key hierarchies and restricted-keyway systems that a residential locksmith cannot touch. We handle commercial re-cores for these tenants on a regular basis, usually after-hours, usually because an employee has been terminated and access has to be revoked before the next business day. The work requires matching mortise lock cylinders to the existing keyway, coordinating with the building’s master key, and updating the key control log. This is not a side job for us. It is a core part of our week in Woburn.

Trusted Brands We Service in Woburn
We work on the full spectrum, from entry-grade Kwikset and Schlage found in most Woburn single-family homes to high-security cylinders from Medeco, Mul-T-Lock, and Sargent in commercial settings. For Woburn customers who already have a Baldwin or Yale smart lock installed and are having trouble with it, we service those too. We stock common parts for these brands and keep a supply of mortise-to-modern conversion kits for older Woburn doors that were built for heavy mortise lock bodies, not modern cylindrical deadbolts. When we need a part we don’t stock, we source it same-day from suppliers along the Route 128 corridor rather than making you wait a week.
Common Lock Installation & Rekey Problems We See in Woburn Homes
- Frozen deadbolt cylinders from inland freeze-thaw. Woburn sits north and inland of Boston, which means colder nights and harder freeze-thaw cycles than coastal towns like Malden or Medford. Moisture gets into the cylinder, freezes, and the key will not turn. We thaw and lubricate first, and only replace when the cylinder is actually damaged.
- Swollen wooden door frames in winter. The same freeze-thaw cycle makes wooden door frames in older Woburn homes swell and rack. The deadbolt throws fine in October and misses the strike plate in February. We re-align strike plates and adjust the door rather than selling a new lock that would not fix the real problem.
- Triple-decker landlords losing key control. After every tenant turnover, the landlord collects keys, but copies almost certainly exist. Without a rekey or a restricted keyway, a former tenant’s copy becomes a building-wide risk. We rekey every cylinder after every turnover as standard practice for Woburn multifamily owners.
- Original mortise locks on pre-war homes. Many Woburn two-families and older single-family homes still have original mortise lock bodies from the early 20th century. Replacement parts are increasingly hard to source, and homeowners often want to convert to a modern deadbolt without destroying a solid wood door. We do the conversion in place, keeping the original trim where possible.

FAQs - Lock Installation & Rekey in Woburn
Same-day in most cases, with the rekey itself taking 30-60 minutes once we are on site. We prioritize tenant-turnover work because we know a vacant unit in a Woburn triple-decker is a liability until the keys are changed. Call (331) 310-8471 and we will give you a written price and a same-day window.
Yes. Cummings Park tenants typically operate under a restricted keyway controlled by the building or the tenant’s security team, and the cylinders are matched to that keyway. Swapping in a residential cylinder would break the key control system and fail a security audit. We match the existing keyway and maintain the key control log as part of every commercial re-core we do in Woburn.
Usually yes, but it is a conversion job, not a direct swap. The existing mortise lock body has to be removed or left non-functional, the door prepped for a cylindrical deadbolt, and a retrofit kit installed. We do this regularly on Woburn Capes and ranches built before cylindrical locks became standard. The door stays intact and the original trim can often be reused.
Because an unrestricted key can be copied for less than five dollars at any hardware store in Woburn, and there is no way to know how many copies exist. Returning the keys is not the same as returning all the keys that were ever made. A rekey makes every previous copy useless, and a restricted keyway makes future copies impossible without authorization. Landlords who skip the rekey are betting their building’s security on a promise from someone who no longer lives there.
We pick or bypass the lock rather than forcing the door, and we do it without damaging the door, frame, or hardware. In Woburn condos and apartments, the door often belongs to the building or the freeholder, not the resident, so destructive entry creates a repair bill someone has to eat. We use picks, bypass tools, and in rare cases, drilling only as a last resort when the cylinder itself is the cheapest part to replace. Non-destructive methods are always our first option.

We rekeyed a two-family triple-decker near Woburn Center after a tenant turnover, swapping the original mortise lock cylinders to new Schlage pin and tumbler cores so the previous tenant’s keys stopped working without replacing the aging hardwood doors. That same week, a Cummings Park biotech tenant called us after-hours to re-core three office locks immediately after an employee termination, keeping their restricted keyway intact and their key control log clean. That split, residential and commercial, old housing stock and modern restricted keyways, is what a week in Woburn actually looks like for us.
