Sudbury isn’t a typical suburban Boston town. The Route 20 corridor still holds one of the densest concentrations of pre-1800 colonial homes in Middlesex County, many with original mortise lock sets and skeleton-key hardware that stopped being standard equipment a century ago. We’ve built our Sudbury service around that reality. Our Lock Installation & Rekey team carries antique lock parts you won’t find at the Framingham supply houses, and we know how to install modern deadbolts and smart locks without damaging doors that have survived three hundred New England winters.
Why Strongbox Lock & Safe Co. Is Sudbury’s Preferred Lock Installation & Rekey Company

No bait, no switch, no “it took longer than expected” add-ons.
Our 90-Day Done Right Promise covers every job in Sudbury with a written guarantee. If something isn’t right, we come back. No paperwork to file, no argument. That’s the standard we’ve kept for four decades, and it’s why Sudbury homeowners call us back when they add a carriage house, convert a barn, or finally upgrade that side door they’ve been meaning to fix.

Our Lock Installation & Rekey Services in Sudbury
Smart Lock Installation
Smart lock installation in Sudbury presents a specific challenge: most pre-1800 colonial doors lack the 2-1/8-inch crossbore that modern smart locks require. We’ve developed methods for these installs that don’t compromise the door. On a recent call along Boston Post Road, we serviced a 1720s colonial where the owner wanted to upgrade to a Schlage smart lock but keep the antique mortise lock functional. We installed a retrofit deadbolt that works alongside the original skeleton-key mechanism, ensuring modern security without compromising historic integrity. For newer Sudbury homes, smart lock installation is straightforward and usually completed in under an hour.
Typical smart lock installation in Sudbury: $220-$380 for standard doors; $340-$480 for historic doors requiring custom backset adapters or mortise retrofit.
Keyless Entry
Keyless entry systems are popular in Sudbury’s larger-lot properties where owners want controlled access for housekeepers, caretakers, or equestrian staff without distributing physical keys. We install keypad and proximity-card systems on main residences, carriage houses, and detached garages. For Sudbury’s many multi-structure properties, we can key all entry points to a single code or card, or maintain separate access zones. Keyless entry installation in Sudbury typically runs $280-$520 depending on the number of doors and whether we’re integrating with existing hardware.
Keypad Lock Installation
Keypad locks bridge the gap between traditional keyed entry and full smart-home integration. In Sudbury, we see strong demand for weather-resistant keypad models on barn doors, pool houses, and garden sheds where carrying a key is impractical. The freeze-thaw cycles that hit Sudbury’s inland location hard mean we specify hardware rated for temperature extremes, not the residential-grade units that fail after a single harsh winter. Keypad lock installation in Sudbury: $180-$320.
Biometric Lock Installation
Biometric locks remain a niche request in Sudbury, but we’ve installed fingerprint readers for home offices, wine cellars, and gun rooms in properties where the owner wants access restricted to specific individuals without the complication of codes or keys. These installs require precise alignment and calibration; we don’t rush them. Biometric lock installation in Sudbury: $340-$580.
Key Duplication
Key duplication in Sudbury isn’t always a five-minute job. Skeleton keys for antique mortise locks, restricted keyways for Medeco or Mul-T-Lock systems, and padlock keys for outbuilding hardware all require specialized equipment. We carry blanks and cutting machines for the full range of residential and commercial key types used in Sudbury properties. Standard key duplication: $4-$12; antique or restricted keyway duplication: $18-$45.
Electronic Lock Repair and Rekeying
Electronic locks in Sudbury fail predictably: battery corrosion in unheated outbuildings, moisture infiltration after driving rain, and circuit board damage from voltage fluctuations during winter storms. We repair what can be repaired and replace what can’t, always with upfront pricing. Electronic lock service in Sudbury: $120-$280 for repair; $180-$340 for replacement with rekeying.

Trusted Brands We Service in Sudbury
We stock and install Schlage, Medeco, Kwikset, and Abloy hardware with local inventory for Sudbury customers. That means faster turnaround and no waiting for parts to ship from a warehouse three states away. Schlage covers the bulk of residential smart lock and deadbolt installs in Sudbury’s newer homes. Medeco and Abloy serve the high-security deadbolt upgrades we see on the town’s larger properties. Kwikset remains the practical choice for standard residential rekeys and replacements. We match the lock to the door, the security need, and the budget. Not every door needs a $400 deadbolt. Not every door can get by with a $30 one.
Common Lock Installation & Rekey Problems We See in Sudbury Homes
- Mortise lock faceplates crack against shifted door stiles. Sudbury’s historic colonial doors have survived centuries of freeze-thaw cycles, but the wood has moved. An installer who overtightens a mortise lock faceplate against a 200-year-old stile will split it. We hand-fit and shim every antique install.
- Smart-lock installation fails on non-standard door prep. Historic Sudbury doors often measure 1-3/8 inches thick with backsets that don’t match modern templates. We carry custom adapters and have modified strike plates on-site when the standard hardware won’t seat.
- Multi-structure properties end up with mismatched keys. A typical Sudbury service call covers a main house, carriage barn, garden shed, and secondary garage. The barn padlock often uses a different keyway than the residential hardware. We audit every structure and key to a single master key system when the owner wants it.
- Exterior deadbolts bind in winter. Sudbury’s hard-freeze winters, regularly below 0°F, cause wooden door frames in historic homes to contract and shift. Deadbolt throws that slide smoothly in October jam in January. We adjust strike alignment and specify weather-resistant lubricants that don’t gum up at low temperatures.

FAQs - Lock Installation & Rekey in Sudbury
Yes. We rekey antique mortise locks regularly along Sudbury’s Route 20 corridor, where original skeleton-key hardware is still common. The process requires different pinning kits and often custom-fabricated parts that aren’t stocked by standard supply houses. We carry the specialized blanks and tools for this work, and we know how to disassemble these mechanisms without damaging brittle castings that haven’t been opened in decades. Call (877) 664-8139 for an exact quote - estimates are free.
Sudbury’s inland location produces sustained hard-freeze winters that regularly drop below 0°F, causing wooden door frames in historic homes to contract and shift. The deadbolt throw no longer aligns cleanly with the strike plate. This is predictable and fixable. We adjust strike alignment, specify proper backset depth, and use lubricants rated for extreme cold. If the frame movement is severe, we may recommend a adjustable-strike solution. Call (877) 664-8139 for an exact quote - estimates are free.
For non-standard barn doors in Sudbury, we typically recommend the Schlage Encode Plus or a commercial-grade keypad lock with adjustable backset and thick-door mounting hardware. Most residential smart locks max out at 1-3/4 inch door thickness. Barn doors often run 2 inches or more. We measure on-site, specify the right hardware kit, and handle the install. Call (877) 664-8139 for an exact quote - estimates are free.
Yes, and this is one of our most common requests in Sudbury, where single properties often span four or five structures. We audit every lock, identify compatible keyways, and either rekey existing hardware to a master key system or replace incompatible locks. The barn padlock is usually the limiting factor - many padlocks use a different keyway than residential deadbolts. We stock padlock models that match standard residential keyways. Call (877) 664-8139 for an exact quote - estimates are free.
Keep them if they’re functional, or if they contribute to the home’s historic character. We can install modern deadbolts alongside original mortise locks, giving you contemporary security without removing hardware that predates the American Revolution. Replacement makes sense only when the mortise mechanism is beyond repair and parts are unavailable. We’ll inspect and give you a straight assessment. Call (877) 664-8139 for an exact quote - estimates are free.
