We’ve been serving Sandown and the Route 121 corridor for over 42 years. We know the difference between a 1978 raised ranch off Phillips Road and a seasonal cottage on Angle Pond. That matters because the lock that fails in March after a hard freeze needs a different fix than the one that quits in July. We stock parts for both.

Our Lock Installation & Rekey Services in Sandown
Smart Lock Installation
Smart lock installation in Sandown runs $280-$520 for most residential doors, including Wi-Fi bridge setup and smartphone app pairing. We install Yale Assure and Schlage Encode lines that integrate with existing home automation systems common in Sandown’s newer construction and renovated colonials. For the seasonal cottage owner on Angle Pond, we configure remote access codes that let caretakers or rental guests in without a physical key exchange. We match the finish to your existing Baldwin or Kwikset hardware so the smart lock does not look like an afterthought on a custom door.
Keyless Entry Systems
Keyless entry installation in Sandown typically costs $220-$440, depending on whether we are retrofitting a standard bore hole or adapting a mortise pocket on an older door. Many Sandown homeowners with carriage-house doors - the kind with custom wood panels and bronze or black iron hardware - worry that keyless entry means bulky, mismatched equipment, but our Automotive Locksmith in Sandown colleagues refer residential clients to us for exactly this reason. It does not. We source low-profile keypads from Medeco and Sargent that mount cleanly and operate in temperatures down to -20°F, which matters when your garage door keypad sees six months of New Hampshire winter.
Keypad Lock Installation
Keypad lock installation for Sandown homes runs $180-$340 for standalone units, $260-$480 if integrated with an existing alarm system. We see heavy demand for these on detached garages and outbuildings along Route 121 and Phillips Road, where homeowners want contractor or family access without duplicating keys. Southern NH’s hard freeze-thaw cycles destroy cheap keypad electronics; we install units with sealed membrane switches rated for moisture and temperature swing. The price we quote is the price you pay. No add-ons for “programming fees” or “service charges.”
Biometric Lock Installation
Biometric lock installation in Sandown starts at $340 and runs to $680 for multi-factor units with fingerprint plus PIN backup. These make sense for Sandown homeowners with home offices, gun rooms, or workshops containing valuable equipment. We have installed fingerprint readers on custom carriage-house doors where the owner wanted zero visible hardware change from the street. The biometric module hides inside a standard-looking escutcheon. We calibrate sensitivity for dry winter skin and calloused hands - real-world conditions that out-of-box settings rarely handle.
Electronic Lock Repair & Replacement
Electronic lock repair in Sandown costs $120-$280 if the issue is software, wiring, or power; replacement runs $240-$520 if the mechanism has failed. We service electronic strikes, mag locks, and access control as our Commercial Locksmith in Sandown for small commercial properties along Main Street and Route 121. Many of these systems were installed during the 2000s and use obsolete protocols. We upgrade them to current standards without replacing the entire door hardware.
Key Duplication
Key duplication in Sandown is $8-$24 per key depending on blank type - standard Kwikset or Schlage at the low end, Medeco or Mul-T-Lock high-security at the upper. We cut keys by code from lock impressions, not just copies of worn originals. That matters for Sandown’s older homes where the original key has been copied ten times and no longer works smoothly. A key cut to factory specification opens like new.

Trusted Brands We Service in Sandown
We install and service Kwikset, Medeco, Yale, and Baldwin in Sandown, with most common parts stocked on our service vehicles. That means a Baldwin Estate mortise lock for your carriage-house door or a Medeco high-security cylinder for your home office does not require a two-week order. We also carry Schlage B-series and Sargent commercial-grade hardware for the 1970s-1990s suburban homes that dominate Sandown’s housing stock. Fast turnaround matters when you are standing outside a frozen cottage in April. We will be there when we say.
Common Lock Installation & Rekey Problems We See in Sandown Homes
- Frost-heaved door frames bind strike plates every spring. Southern NH’s ground-heaving from winter frost shifts door frames enough to misalign deadbolt throws. A standard rekey cannot fix this - we relocate the strike plate and sometimes shim the frame to restore smooth operation.
- Ice intrusion seizes cylinders on detached garages and outbuildings. Sandown’s hard freeze-thaw cycles push moisture into exterior lock cylinders, expanding and contracting until the pins freeze solid. Complete cylinder replacement is usually required; rekeying a seized cylinder is not practical.
- Aging Kwikset locksets from 1970s-1990s builder-grade homes cannot accept modern keyways. The suburban expansion that brought Massachusetts commuters to Sandown left thousands of homes with locksets that are increasingly difficult to rekey to current standards. We replace with compatible hardware that matches your existing key system.
- Angle Pond cottage deadbolts corrode solid over unheated winters. Last spring, a homeowner on Angle Pond Road called us after finding the deadbolt on their carriage-house door frozen solid after the cottage sat unheated all winter. We replaced the corroded Schlage B-series lock with a Baldwin Estate mortise lock that withstands freeze-thaw cycles and matched the custom bronze finish of their existing hardware. Sandown’s seasonal cottage communities along Angle Pond create a predictable spring surge in lock installation and rekey work, as owners returning to unheated properties find deadbolts and padlocks corroded or frozen solid - a demand pattern absent in the fully residential neighboring towns of Hampstead and Danville.

FAQs - Lock Installation & Rekey in Sandown
No - Kwikset and Schlage use different keyways that are not cross-compatible, and the builder-grade Kwikset locksets common in 1980s Sandown homes often cannot accept modern keyway standards even within the same brand. We replace the Kwikset with a current-grade lock that matches your preferred key system. Call (877) 664-8139 and we will quote the replacement flat over the phone.
We replace the hardware. A deadbolt frozen solid from corrosion or ice intrusion cannot be rekeyed - the internal components are damaged beyond pin replacement. We install weather-resistant hardware rated for Sandown’s freeze-thaw cycles, matched to your door’s finish. Schedule before the spring rush; call (877) 664-8139.
Yes - we specialize in low-profile smart locks that preserve the custom appearance of carriage-house and wood doors. Yale and Schlage units fit standard bore holes without visible modification, and we match bronze, black iron, or nickel finishes to existing hardware. Call (877) 664-8139 for a free estimate.
Yes, if the lock is in functional condition. Antique mortise locks near Sandown’s historic town center often need pin replacement or spring repair before rekeying. We stock period-appropriate key blanks and can match the lock to a modern key system while preserving the original hardware. Call (877) 664-8139 to schedule an evaluation.
Southern NH’s winter frost heaves the ground beneath your door frame, shifting it enough to misalign the strike plate and stress the deadbolt throw. The binding is structural, not a lock problem. We relocate the strike plate and shim the frame to compensate. A standard rekey will not fix it. Call (877) 664-8139 - estimates are free.
