We’ve worked in Yonkers for over 42 years. We know the southwest tenements with their original mortise hardware. We know the 1950s colonials up near Crestwood with their Kwikset deadbolts. And we know that a locksmith who treats Yonkers like any other Westchester town will miss what actually matters here. That’s why our Lock Installation & Rekey team trains specifically on the pre-war building stock that defines this city. Whether you need a single rekey on a garden apartment or a full master-key overhaul for a six-story walkup, we quote the real price on the phone and back every job with our 90-Day Done Right Promise.
Why Strongbox Lock & Safe Co. Is Yonkers’s Preferred Lock Installation & Rekey Company
Our reputation in Yonkers was built one building at a time. Landlords on Ashburton Avenue and South Broadway call us back because we show ID at the door, wear a uniform, and leave written documentation of every key code. No voicemail trees, no callback queues. A live person answers every call, 24/7, including nights, weekends, and holidays.
We’ve earned strong reviews from Yonkers customers who specifically mention our flat-price honesty. After decades of $19-ad scams and bait-and-switch operators in this market, homeowners aged 55-75 tell us the same thing: they want the job done once, done right, and never thought about again. That’s exactly what we deliver.
Response time to Yonkers runs 30-45 minutes from our dispatch. We carry Sargent mortise cylinders, Medeco high-security cores, and standard cylindrical hardware on every truck, so we’re not making a second trip because your building has hardware from 1927. We also stock electronic and smart lock components for the growing number of Yonkers property owners modernizing their pre-war units.
Our local knowledge runs deeper than hardware. We understand New York State’s rekeying requirements for rental units. We know which Yonkers buildings have cast-iron frames that swell in January. And we know that a master-key system repinned piecemeal by four different locksmiths over thirty years is not a quick afternoon fix. We plan for it.
Our Lock Installation & Rekey Services in Yonkers
Smart Lock Installation
Smart locks in Yonkers require more thought than a quick Amazon purchase. The pre-war brick doors in Nodine Hill and the Hollow need specific retrofit adapters to accommodate WiFi deadbolts without damaging original mortise pockets. We install Yale and Schlage smart locks with reinforced strike plates that account for the oblong wear patterns common in these buildings. Our technicians will tell you honestly if your door frame can support a smart lock or if an electronic lever set makes more sense. We don’t sell you hardware that fights your building.
Keyless Entry Systems
Keyless entry solves a real problem for Yonkers landlords: no more tracking physical keys between tenant turnovers. We install keypad and card-access systems in multi-unit buildings from Getty Square to Ludlow Park. For the six-story walkups on South Broadway, we can integrate keyless entry with a master-key override that still complies with fire code. Every installation includes training for your superintendent and written documentation of all access codes. The price we quote is the price you pay. No add-ons after the truck arrives.
Electronic Lock Installation
Electronic locks bridge the gap between traditional hardware and full smart home integration. In Yonkers’s 1950s-1960s colonials near Crestwood, we often recommend electronic deadbolts with auto-lock features for homeowners who want convenience without complexity. In the pre-war stock, we favor hardwired electronic strikes paired with existing mortise hardware, preserving the building’s character while adding modern access control. We carry Baldwin and Yale electronic components on our trucks for same-day installation in 10702, 10703, 10704, and 10705.
Biometric Lock Installation
Biometric locks, fingerprint readers specifically, make sense for a narrow set of Yonkers applications: owner-occupied brownstones, small condominium buildings with limited units, and certain commercial spaces near the Cross County Parkway. We install Medeco biometric cylinders that integrate with existing high-security key systems. For most Yonkers rental properties, we typically recommend keypad or card access instead, as fingerprint enrollment and deletion between tenants becomes burdensome. We’ll tell you straight if biometric is overkill for your situation.
Key Duplication
Key duplication in Yonkers is not always a five-minute job. Medeco, Mul-T-Lock, and restricted Sargent keyways require authorized duplication with signature verification. We maintain key records for landlords with master-key systems, so when a tenant loses a key on Ashburton Avenue, we can cut a replacement that matches the existing pin code without rekeying the entire building. For standard Kwikset and Yale residential keys, duplication takes under ten minutes while you wait at your door.

Trusted Brands We Service in Yonkers
We install and service Kwikset, Medeco, Yale, and Baldwin hardware, and we stock parts for all four on every Yonkers service call. That matters when your mortise cylinder fails on a Saturday evening and the hardware is from 1987. We don’t substitute. We don’t “make it work” with what’s on the truck. If your building has Baldwin mortise locks, we bring Baldwin components. If your master-key system runs on Medeco, we carry Medeco cores. Our parts inventory is built around Yonkers’s actual housing stock, not whatever a national distributor pushes this quarter. Fast turnaround means the right part, the first time, installed by a technician who shows ID at your door.
Common Lock Installation & Rekey Problems We See in Yonkers Homes
- Mortise lock strike plates worn oblong in Nodine Hill pre-war brick buildings. The original steel strike plates in these 1900s-1940s walkups erode over decades of tenant turnover, preventing deadbolts from fully extending. Come January, when freeze-thaw cycles swell the cast-iron frames, these worn strikes cause complete lock seizures that trap residents inside or out.
- Piecemeal repinning of master-key systems in South Broadway tenements. When four different locksmiths work on the same building across thirty years, each adds their own pinning logic. The result: keys that work in unit 2A but not 2B, superintendents carrying twelve keys for six units, and security gaps where former tenants still have access.
- Cast-iron door frames swelling with winter moisture in the Hollow. Yonkers’s Hudson River valley topography concentrates humidity, and repeated freeze-thaw cycles cause older steel and cast-iron frames to expand. New cylindrical deadbolts bind against these swollen frames unless the strike pocket is ground down or the frame itself is replaced.
- Original mortise hardware incompatible with modern smart lock retrofits. Homeowners in southwest Yonkers buy WiFi deadbolts online, then discover their 1920s doors have no standard bore hole and a mortise pocket that conflicts with the smart lock’s footprint. We see this attempted DIY weekly.
Pricing for Lock Installation & Rekey in Yonkers, NY
We quote flat prices on the phone before any work begins. No bait, no switch, no “service call plus labor plus parts” arithmetic at your door.
| Service | Typical Range in Yonkers |
|---|---|
| Standard residential rekey (cylindrical lock) | $89-$145 |
| Mortise lock rekey or cylinder replacement | $145-$220 |
| Master-key system rekey (per cylinder) | $45-$75 |
| Electronic lock installation | $280-$450 |
| Smart lock installation (with retrofit adapter) | $220-$340 |
| Full master-key system overhaul (24-unit building) | $1,800-$3,200 |
What moves the needle: mortise hardware costs more than cylindrical because of the specialized labor and parts. Master-key overhauls scale with building size and the condition of existing pinning. Smart lock retrofits on pre-war doors require custom strike adapters that add $40-$80 to standard pricing.
We honor our standing offers: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-ups, and a permanent 5% discount for seniors and veterans. Estimates are free. Call (877) 664-8139 for your exact quote.

FAQs - Lock Installation & Rekey in Yonkers
Yes, we can retrofit modern deadbolts into most pre-war Yonkers doors, but the method depends on your specific frame and mortise pocket. In buildings on Nodine Hill and the Hollow, we often preserve the original mortise lock for aesthetic and structural integrity while adding a separate cylindrical deadbolt above it. For doors with severely swollen cast-iron frames, we may need to grind the strike pocket or recommend a mortise cylinder replacement instead. We assess this on-site and quote the full price before cutting anything. Call (877) 664-8139 for a free estimate.
New York State requires rekeying or replacing locks between every tenant turnover, with no exceptions for “trusted” departures. For a building like yours with constant turnover, we recommend establishing a standing relationship with a single locksmith who maintains your master-key records. Last winter, we rekeyed an entire 24-unit pre-war building on Ashburton Avenue after the master-key system had been repinned piecemeal by four different locksmiths over 30 years. We replaced the worn mortise cylinders with new Sargent cores and re-pinned the master-key to a single code, cutting emergency lockout calls for that landlord from six per winter down to zero. Call (877) 664-8139 to set up a building account.
Yes, in most cases we can rebuild your master-key system without replacing the physical lock bodies. The problem is almost always cumulative pinning errors from multiple locksmiths adding their own codes over decades. We decode each cylinder, identify conflicts, and re-pin to a clean master-key hierarchy. For a typical six-story Yonkers walkup, this takes one business day and costs 60-70% less than full lock replacement. We back the rebuild with our 90-Day Done Right Promise. Call (877) 664-8139 to schedule a system audit.
Sometimes, but not always with the hardware sold at big-box stores. The mortise pockets and thick brick molding on 1900s-1940s Yonkers walkups often conflict with standard smart lock footprints. We install Yale and Schlage smart locks with custom retrofit adapters for these doors, but we won’t sell you a smart lock if your frame can’t support it properly. For buildings with swollen cast-iron frames that shift seasonally, we typically recommend hardwired electronic strikes instead. We assess your specific door on a free site visit. Call (877) 664-8139 to book.
The Hudson River shoreline and Yonkers’s valley topography concentrate winter moisture, and repeated freeze-thaw cycles cause older steel and cast-iron door frames in pre-war walkups to swell and seize deadbolts. This produces a predictable spike in emergency lockouts each January and February that is more severe than in the higher-elevation eastern neighborhoods. The fix is usually two-part: grind or replace the swollen strike pocket, and ensure your deadbolt has full throw clearance. We see this exact failure mode dozens of times each winter in southwest Yonkers. Call (877) 664-8139 before January hits and we’ll prevent the freeze-up.
