Our Lock Installation & Rekey Services in Gravesend
Smart Lock Installation
Smart lock installation in Gravesend runs $220-$420 for most residential doors, including Wi-Fi bridge setup and smartphone pairing. We install Yale and Kwikset smart locks that integrate with existing deadbolt prep, which matters on Gravesend’s older doors where drilling new holes can compromise weatherstripping on original frames. For the row houses near Gravesend Bay, we always check door thickness and jamb condition before recommending a model - salt air has warped more than a few door frames here, and a smart lock needs a stable mount to function reliably.
Keyless Entry
Keyless entry systems for Gravesend homes and rentals cost $180-$350 installed, depending on whether you need a standalone keypad or a networked system for multiple units. This is our most-requested upgrade in Gravesend’s multi-family buildings, where landlords on Ocean Parkway and Avenue X need to rekey between tenants without the cost of full cylinder replacement every time. We program master codes, tenant codes, and temporary access codes on-site, and we document everything in writing so you’re never locked out of your own system.
Keypad Lock
Keypad lock installation in Gravesend typically costs $160-$290 for a commercial-grade mechanical keypad, or $200-$380 for an electronic model with audit trail capability. The mechanical units hold up better on exterior doors exposed to Gravesend Bay’s salt air - no batteries to corrode, no circuit boards to fail. We’ve installed dozens on basement and cellar entrances of Gravesend’s converted row houses, where supers need reliable access without carrying a ring of keys for every building.
Biometric Lock
Biometric lock installation in Gravesend starts at $340 for residential fingerprint readers and runs to $580 for multi-user commercial units with facial recognition. These are less common in Gravesend’s residential stock but increasingly requested for home offices and small commercial spaces along Kings Highway. We verify that your door and frame can handle the hardware weight before quoting - biometric units are heavier than standard deadbolts, and a 90-year-old mortise door needs reinforcement that a newer door does not.
Electronic Lock
Electronic lock installation and repair in Gravesend costs $190-$450, covering everything from basic keypad deadbolts to full access control systems with card readers. Salt corrosion from Gravesend Bay is the enemy here - we specify marine-grade finishes and sealed housings for any electronic lock within three blocks of the water. We’ve replaced too many “indoor-rated” electronic locks that failed within eighteen months on Gravesend’s exposed doorways.
Key Duplication
Key duplication in Gravesend runs $4-$18 per key for standard cuts, and $18-$45 for high-security keys including Medeco and Mul-T-Lock dimple keys. We duplicate on-site for most requests, and we stock blanks for the Eastern European high-security cylinders that are unusually common in this neighborhood. The Russophone community around Kings Highway frequently needs Mul-T-Lock or ABLOY duplicates - brands familiar from Eastern Europe - and we cut those while you wait rather than sending them out to a third party.

Trusted Brands We Service in Gravesend
We install and service Kwikset, Medeco, Yale, and Baldwin hardware in Gravesend, and we stock parts for same-day completion on most jobs. Our truck carries Medeco high-security cylinders and Yale smart lock components specifically because Gravesend’s mix of legacy mortise housings and modern security demands requires both. We don’t show up with one brand and force it to fit - the right lock goes on the right door. For the neighborhood’s many Mul-T-Lock and ABLOY requests, we source through our Brooklyn supply house and can typically have hardware next-day if not in stock.
Common Lock Installation & Rekey Problems We See in Gravesend Homes
- Seized mortise cylinders from salt-air corrosion. Gravesend Bay’s prevailing southwest winds carry salt inland, corroding exposed brass and zinc-alloy lock bodies. We see seized cylinders on Avenue U and Ocean Parkway row houses far more often than in inland Brooklyn zip codes, and the fix is usually full replacement rather than simple rekeying.
- Worn keyways on original 1920s-1950s locks. The original mortise lock sets in Gravesend’s brick row houses have keyways worn smooth by decades of use. Modern keys won’t seat properly, and the only reliable fix is retrofitting a new cylinder housing into the existing mortise case.
- Failed deadbolt throws from galvanic corrosion. Inside zinc-alloy lock bodies, salt air accelerates galvanic corrosion that jams deadbolt throws. NYC building code now requires Grade-1 deadbolts on residential exits, so we upgrade to compliant hardware rather than patching the old unit.
- Misaligned strikes on shifted door frames. Decades of settling in Gravesend’s prewar construction, combined with humidity cycles from the bay, shift door frames enough that latches no longer align with strikes. We diagnose this on arrival and include strike relocation or shim adjustment in our flat quote.

Gravesend’s Unique Lock Challenges: Salt Air and Legacy Hardware
Gravesend’s dense stock of 1920s-1950s attached and semi-detached brick row houses - many still fitted with original mortise lock sets - sits just blocks from Gravesend Bay, where salt air off the water accelerates corrosion of exposed lock cylinders and strike plates far faster than in inland Brooklyn neighborhoods. Compounding this, the neighborhood’s large Russian-speaking and Chinese immigrant population lives heavily in multi-family configurations, generating constant rekeying demand as extended families and tenants cycle through units.
On a prewar row house on Avenue U, we replaced a seized Mul-T-Lock cylinder that had corroded from salt air off Gravesend Bay. The owner, a Russian-speaking landlord, requested the same brand for tenant rekeying - a common retrofit here because of the neighborhood’s familiarity with Eastern European high-security locks.
This combination of coastal geography and immigrant demographics creates a niche need that defines our Lock Installation & Rekey in Gravesend work: retrofitting high-security cylinders into salt-damaged mortise locks. It’s not a standard service call, and technicians who don’t know Gravesend’s housing stock often quote wrong or arrive unprepared. We’ve learned to bring mortise cylinder adapters, marine-grade finishes, and the patience to explain why a simple rekey won’t solve a corrosion-seized mechanism.

FAQs - Lock Installation & Rekey in Gravesend
Salt-laden air from Gravesend Bay accelerates corrosion inside lock cylinders and strike plates, especially on doors within three blocks of the water. The corrosion binds pins, swells zinc-alloy bodies, and eventually seizes the mechanism entirely. We specify marine-grade finishes and sealed housings for Gravesend’s exposed doorways, and we recommend annual lubrication with a graphite-based product rather than oil, which attracts salt residue. Call (877) 664-8139 - we’ll diagnose whether a rekey or full replacement is the right fix, and the estimate is free.
Sometimes, but often the keyway is too worn or the internal mechanism too corroded for reliable rekeying. We inspect the mortise case on arrival - if the body is sound, we can retrofit a modern cylinder into the existing housing, preserving your door’s original hardware while meeting current security standards. This Gravesend-specific retrofit runs $85-$180, and we carry the adapters to do it same-day. Call for an exact assessment - estimates are free.
For Gravesend’s multi-family buildings, we recommend a Grade-1 deadbolt with removable core or a keyless entry keypad, depending on tenant turnover frequency. Keyless systems eliminate rekeying costs between tenants - program a new code instead of changing cylinders. For landlords who prefer traditional keys, Medeco removable-core cylinders allow fast rekeying without disassembling the lock. We’ve installed both approaches on Ocean Parkway and Avenue X buildings. Call (877) 664-8139 to discuss which fits your management style.
Locks on Gravesend’s bay-proximate row houses typically need replacement every 12-18 years rather than the 20-25 year lifespan expected inland, due to accelerated salt corrosion. If your deadbolt throw is sticking, your key requires jiggling, or you see greenish corrosion on the cylinder face, the mechanism is already compromised. We inspect and quote flat - no charge to look. Call (877) 664-8139 for a free condition check.
Yes, and we do it regularly in Gravesend, but the installation requires more than swapping hardware. Original row house doors often need strike reinforcement, frame shimming, and sometimes drilling alignment that respects weatherstripping and historic trim. We assess door thickness, jamb condition, and frame squareness before quoting - a flat price that includes all necessary modification, not just the lock itself. Most Gravesend keyless installations run $180-$350 completed. Call for a free on-site estimate.
