Why Strongbox Lock & Safe Co. of New York City Is Eastchester’s Preferred Lock Installation & Rekey Company
Eastchester homeowners have called us for over 42 years because we understand what their houses are built from. The 1920s-1950s housing stock here - Colonials, Cape Cods, and Tudor Revivals with solid-wood stiles and original mortise lock bodies - demands a different skill set than the hollow-core doors and standard cylindrical locks that chain franchises are equipped to handle.
Our reputation in Eastchester is built on jobs that other locksmiths walked away from. The antique mortise set on a 1936 Wisteria Drive home that needed a smart lock retrofit. The frozen deadbolt on a north-facing Bronxville Road entry after a January polar vortex. We don’t subcontract to unchecked technicians, and we don’t quote $19 over the phone only to charge $400 at the door. Every Strongbox technician is background-checked, uniformed, and presents company ID before touching your lock.
Calls are answered by a live person, 24/7 - nights, weekends, holidays, no exceptions. The price we quote is the price you pay. And every job carries our 90-Day Done Right Promise: backed in writing, no paperwork, no arguing. If it’s not right, we come back.
Our Lock Installation & Rekey Services in Eastchester
Smart Lock Installation
Smart lock installation in Eastchester runs $220-$420, with most pre-war doors requiring a custom adapter plate to bridge the original mortise pocket. We install Wi-Fi-enabled deadbolts that integrate with existing home automation systems, and we machine spacers on-site when your 1⅜-inch stile won’t accept a standard cylindrical housing. Last winter, we installed a Schlage Encode on a 1936 Colonial on Wisteria Drive, near Tuckahoe Road, where the original mortise lock cylinder had frozen solid during a January polar vortex. We had to machine a custom adapter plate to bridge the old mortise pocket and the new deadbolt, then rekey the existing mortise lock to match - all while the homeowner waited in their car because the front door was inoperable at 6°F. The job took two hours. The door never lost its original character.
Keyless Entry
Keyless entry systems for Eastchester homes range from $180-$340 for keypad deadbolts to $380-$620 for full-entry sets with integrated handles. We specify hardware rated for Westchester’s freeze-thaw cycles, because a north-facing door under dense canopy will destroy consumer-grade electronics within one winter. For the older blocks near the Tuckahoe Road corridor, we source escutcheons and backset components that fit your door’s original dimensions rather than forcing a retrofit kit sized for modern 1¾-inch doors. Baldwin and Sargent keyless hardware holds up well here. We quote flat before we roll.
Keypad Lock Installation
Keypad lock installation in Eastchester costs $160-$290 for most residential applications. These are popular with homeowners transitioning from adult children at home to empty-nest routines - no more spare keys under the planter. We program multiple user codes, set temporary access for contractors or housekeepers, and make sure the strike plate is adjusted for your door’s seasonal wood movement. Eastchester’s decades of freeze-thaw cycles shift frames subtly. A keypad lock that works fine in September can bind by March if the installation doesn’t account for it.
Biometric Lock Installation
Biometric lock installation in Eastchester starts at $340 and runs to $580 for fingerprint-enabled deadbolts with backup key override. These units draw more power and require more precise door prep than standard keypads. On pre-war doors with mortise pockets, we often need to reinforce the stile or machine a custom mounting surface. We won’t install a biometric unit on a door that can’t support it properly. That’s not how you build a 42-year reputation.
Electronic Lock Repair & Rekeying
Electronic lock repair in Eastchester typically runs $120-$240, including reprogramming, battery-system replacement, and strike adjustment. Rekeying an existing electronic lock - changing the internal pin configuration so old keys no longer work - costs $45-$85 per cylinder. We rekey antique mortise locks, modern deadbolts, and everything between, matching all cylinders to a single key if that’s what you need.
Key Duplication
Key duplication in Eastchester is $8-$18 for standard residential keys, $18-$35 for high-security blanks including Mul-T-Lock and Abloy. We cut on-site from code or by impression, and we stock the restricted-keyway blanks that many Eastchester homeowners have upgraded to after security concerns near the Mount Vernon border. Duplicate keys are tested in your lock before we leave. No “it should work” - it works, or we cut it again.

Trusted Brands We Service in Eastchester
We install and service Baldwin, Mul-T-Lock, Sargent, and Abloy hardware throughout Eastchester, with replacement parts stocked for same-day resolution on most residential calls. These aren’t brands we special-order when needed - they’re on our trucks, because Eastchester’s pre-war doors punish inferior hardware and reward precision engineering. Baldwin’s solid-brass mortise sets complement original 1920s entries without looking like an afterthought. Mul-T-Lock’s high-security cylinders fit retrofitted mortise bodies with proper adapter plates. Sargent and Abloy commercial-grade hardware holds up on side entries that see heavy family traffic. We specify the right lock for the right door, not just what’s on the truck.
Common Lock Installation & Rekey Problems We See in Eastchester Homes
- Standard deadbolts forced into mortise pockets without transition plates. Big-box installers routinely leave a gap that compromises both security and finish. The original mortise body is removed, a cylindrical deadbolt is drilled in off-center, and the homeowner is left with a door that looks wrong and locks poorly. We machine custom adapter plates or specify mortise-compatible hardware instead.
- Smart locks failing on north-facing doors under dense canopy. Eastchester’s mature oak and maple canopy keeps shaded entries damp year-round. Consumer-grade smart locks not rated for outdoor exposure take on moisture, then freeze in January. By February the touchscreen is dead. We specify IP-rated hardware and proper door sealing for these microclimates.
- Seized mortise cylinders replaced with generic tubular locks without strike adjustment. Spring arrives, the wood swells, and the new lock binds because the strike plate was never moved to match the seasonal shift. We adjust or replace strike plates as part of every installation, and we understand that Eastchester’s solid-wood doors move more than modern engineered frames.
- Keyway corrosion from decades of Westchester freeze-thaw cycling. Original brass internals in pre-war mortise sets degrade slowly, then fail suddenly. We can often rebuild these with specialty components from our hardware suppliers, preserving the original lock body that matches your home’s period hardware.

FAQs - Lock Installation & Rekey in Eastchester
Yes, in most cases we can install a smart lock on your 1930s Colonial door by machining a custom adapter plate that bridges the existing mortise pocket, avoiding new through-bores. The original mortise body often stays in place as a secondary lock, or we rekey it to match the new deadbolt. We’ve done this on dozens of homes near Tuckahoe Road and throughout the 10709 ZIP. The door keeps its character. You get modern access. Call (877) 691-7931 for a free assessment of your specific door.
Your deadbolt sticks after winter because Westchester’s hard freeze-thaw cycles drive moisture into the cylinder, then spring warmth causes wood-frame swelling that misaligns the strike plate. Eastchester’s mature tree canopy keeps north- and east-facing entries damp, accelerating both corrosion and dimensional shift. We fix this by cleaning and lubricating the cylinder with graphite (never oil, which gums in cold), then adjusting or relocating the strike plate to match the door’s seasonal position. Sometimes the mortise body itself needs shim adjustment. The fix usually takes under an hour. Call (877) 691-7931 to schedule.
Yes, we rekey antique mortise locks throughout Eastchester, including the pre-war homes along Tuckahoe Road and surrounding blocks. These locks use different pin configurations and often require specialty blanks or custom-cut levers that big-box key machines can’t duplicate. We carry the hardware and have the bench skills. Rekeying costs $45-$85 per cylinder, and we can key all your locks alike so one key works every door. Estimates are free - call (877) 691-7931.
Schlage Encode and Baldwin Evolved handle Eastchester’s older doors well when paired with our custom adapter plates, because their mounting hardware tolerates the thicker stiles and mortise-pocket spacing common in pre-war construction. We avoid brands with narrow mounting footprints or plastic housings that crack in cold snaps. For doors under heavy canopy, we specify units with sealed battery compartments and IP-rated touchpads. The right brand depends on your door’s exact thickness, the mortise pocket dimensions, and your home’s Wi-Fi coverage. We’ll assess all three on-site and quote before any work begins.
Yes, north-facing locks near the Bronx border freeze more often because they get no winter sun and Eastchester’s dense canopy blocks ambient warming. The Mount Vernon adjacency doesn’t directly cause freezing, but the microclimate is identical - shaded, damp, and exposed to the same polar vortex patterns that drop temperatures below 10°F for days. We recommend graphite lubrication before winter, weatherstripping that deflects wind-driven rain, and for high-risk doors, a lock model with a covered keyway or heated smart-lock option. If you’re already frozen out, our emergency response reaches Eastchester in 30-45 minutes. Call (877) 691-7931.
