Our Lock Installation & Rekey team has been answering calls from Mamaroneck homeowners for decades, and we know the village’s hardware better than most - from the pre-WWII mortise locks in the Washington Square neighborhood to the corroded deadbolts we replace every spring after another Mamaroneck River flood. We’re typically on Palmer Avenue, Mamaroneck Avenue, or the Harbor area within 30-45 minutes of your call.
Why Strongbox Lock & Safe Co. of New York City Is Mamaroneck’s Preferred Lock Installation & Rekey Company

A live person answers every call, 24/7 - nights, weekends, holidays, no exceptions.
We know Mamaroneck’s housing stock intimately. The village core’s late Victorian and Craftsman homes carry original mortise locksets that big-box locksmiths simply don’t stock parts for. The multi-family buildings near Washington Square turn over tenants regularly, and those landlords need rekeying done fast and done right. We handle both, and we carry the hardware to do it in one trip.
Frank Bellomo has led this company for years, and our K.E.Y.S. values - Krafted right, Every time, Your home first, Standing behind it - govern how every technician treats your door. We’re not the $19-ad guys who vanish after the invoice. We plan to be serving Mamaroneck in thirty years, and we act like it.
Our Lock Installation & Rekey Services in Mamaroneck
Smart Lock Installation
Smart locks make particular sense in Mamaroneck’s flood-prone zones. When the Mamaroneck River rises and submerges ground-floor entries, traditional keys get lost, damaged, or simply can’t turn in corroded cylinders. A properly installed smart lock with keypad or app access eliminates that vulnerability. We install Yale and Schlage smart locks rated for coastal humidity, with encrypted wireless protocols that won’t fail when salt air degrades cheaper electronics. Typical smart lock installation in Mamaroneck runs $280-$450 including hardware, programming, and a walkthrough on your phone.
Keyless Entry
Keyless entry systems are our most requested upgrade in the Palmer Avenue corridor, where post-flood rekeying has become a recurring expense for homeowners. After replacing flood-seized deadbolts three times in five years, many Mamaroneck residents switch to Schlage keypad entry - no physical key to corrode, no cylinder to seize, just a code that can be changed in seconds. We install mechanical and electronic keyless systems, and we always recommend models with sealed components for waterfront exposure. Keyless entry installation in Mamaroneck typically costs $220-$390.
Keypad Lock
Keypad locks bridge the gap between traditional hardware and full smart home integration. For Mamaroneck’s multi-family landlords near Washington Square, we install commercial-grade keypad locks that let you issue and revoke tenant codes without rekeying between every lease. The salt air off Long Island Sound destroys standard keypad membranes in 2-3 years; we spec rubberized, sealed keypads from Sargent and Yale that last 8-10 years in coastal conditions. Residential keypad lock installation runs $190-$340 in Mamaroneck.
Biometric Lock
Biometric locks - fingerprint readers - suit Mamaroneck homeowners who want maximum security without carrying anything. The technology has matured; modern readers work reliably even with minor moisture from coastal humidity. We install Mul-T-Lock and Medeco biometric systems with stainless steel housings that resist the salt-air corrosion that kills cheaper units. These are premium installations, typically $480-$720 in Mamaroneck, but for waterfront properties where keys are a constant headache, they pay for themselves in avoided service calls.
Electronic Lock
Electronic locks encompass card readers, proximity fobs, and integrated access control. We install these as our Commercial Locksmith in Mamaroneck for small commercial buildings along Mamaroneck Avenue and in mixed-use developments near the harbor. All electronics are sealed against humidity, with battery backup systems that won’t leave you stranded during a winter storm. Commercial electronic lock installation starts at $340 and ranges to $680 depending on access points and integration requirements.
Key Duplication
We cut keys on-site for Mamaroneck customers, including high-security Medeco and Mul-T-Lock blanks that require authorized dealer credentials. If your original key is corroded from salt-air exposure, we can often decode the lock directly and cut a fresh key to factory specifications. Key duplication runs $8-$35 depending on the blank; high-security keys require our technician to verify lock ownership.

Trusted Brands We Service in Mamaroneck
We stock and install Medeco, Yale, and Baldwin hardware from our service vehicles, which means most Mamaroneck jobs finish in one visit without waiting for parts. Medeco’s restricted keyway systems are popular with Harbor-area homeowners who’ve had enough of flood-damaged locks. Yale’s coastal-grade smart locks hold up to Long Island Sound salt air better than consumer models from big-box stores. Baldwin’s solid brass and corrosion-resistant finishes match the architectural character of Mamaroneck’s pre-WWII homes while outlasting standard hardware by years. We don’t install what we wouldn’t put on our own doors.
Common Lock Installation & Rekey Problems We See in Mamaroneck Homes
- Salt-air cylinder seizure on waterfront properties. Lock cylinders and deadbolt mechanisms facing Long Island Sound corrode internally within 2-3 years, versus 8-10 years inland. The key starts sticking, then won’t turn at all. We replace with marine-grade hardware and stainless fasteners.
- Flood-damaged mortise locksets in historic homes. Brackish Mamaroneck River water leaves mineral residue in original mortise mechanisms, causing strike plates to expand and jam. These require disassembly, cleaning, and often period-compatible replacement parts we special-order for Craftsman and Victorian-era doors.
- Freeze-thaw keyway seizures in unheated garages. Winter temperature swings crack cylinder plug seals on detached garages throughout the village, letting moisture freeze overnight and seize the keyway by morning. We replace with sealed all-weather cylinders and recommend annual lubrication before November.
- Multi-family rekeying between tenants. High turnover in Washington Square and harbor-adjacent rentals means landlords need fast, reliable rekeying - often same-day between lease signings. We maintain master key systems and keep common cylinder configurations in stock for immediate swap-out.

FAQs - Lock Installation & Rekey in Mamaroneck
They don’t, because we don’t install garage door springs - we’re locksmiths, not garage door technicians. But if your lock hardware on garage entries is failing that fast, salt air from Long Island Sound is the culprit. Exposed cylinders and deadbolts on garage doors facing the Sound corrode 3-4 times faster than inland hardware. We replace them with stainless steel components and sealed cylinders rated for coastal exposure. Call (877) 691-7931 for a free assessment of your garage entry hardware.
Yes. Standard deadbolts fail predictably after flood exposure - the cylinder corrodes internally, the bolt mechanism jams, and the strike plate swells from moisture absorption. We install Baldwin corrosion-resistant deadbolts with stainless steel bolts and sealed cylinders for river-adjacent properties in the Palmer Avenue and Mamaroneck Avenue corridors. These cost $40-$80 more than standard grade but outlast them by years in flood conditions. The price quoted on the phone includes everything - hardware, installation, and a written 90-Day Done Right Promise.
Usually, yes. Mamaroneck’s pre-WWII housing stock - the Craftsman and Victorian-era homes in the village core - often carries original mortise locksets that modern locksmiths won’t touch. We stock replacement cylinders and period-compatible hardware for the most common manufacturers, and we can fabricate adapters for oddball sizes. When original parts are unobtainable, we source solid brass replacements that maintain your door’s architectural integrity. Rekeying a vintage mortise lock in Mamaroneck typically runs $180-$290; full replacement with period hardware runs $260-$420. Call for a free look - we’ll tell you honestly if it’s serviceable.
An Automotive Locksmith - Mamaroneck service is available too, but for a smart lock installation on a flood-prone ground-floor entry in Mamaroneck runs $280-$450, including a coastal-rated Yale or Schlage unit with sealed electronics. We remove and properly dispose of the flood-damaged hardware, inspect the door frame for swelling or warping, and program the new lock to your phone before we leave. The keypad or app access means no physical key to lose or corrode in the next flood. That’s the flat price - no trip charge, no “plus tax” surprise. Seniors and veterans save an additional 5%.
For Harbor-area garages in Mamaroneck, we specify stainless steel deadbolts, sealed all-weather cylinders, and nylon or polymer internal components that won’t bind when salt air penetrates the housing. Baldwin and Medeco both offer marine-grade finishes that hold up to Long Island Sound exposure without the pitting and sticking you get from standard hardware. We also recommend annual lubrication with a graphite-based protectant before winter - freeze-thaw cycles crack seals that salt air has already weakened. Hardware and installation for a corrosion-resistant garage entry typically runs $220-$340. Call (877) 691-7931 and we’ll walk through your specific setup.
