Why Strongbox Lock & Safe Co. Is East Flatbush’s Preferred Lock Installation & Rekey Company
We’ve served Brooklyn homeowners for over 42 years, and East Flatbush has been central to that work. The 1920s-1950s semi-detached brick two-families that define this neighborhood demand a different skill set than the new construction in other parts of the borough. Our technicians carry the NYC DCA locksmith license, show it at your door with photo ID, and quote a flat price before the truck rolls.
Our customers in East Flatbush call us back because we understand the two-household dynamic - owner downstairs, tenant upstairs, separate keying systems, one building. We recently rekeyed a 1930s semi-detached on Rutland Road where the owner needed separate keys for their ground-floor unit and the tenant’s upstairs apartment. The old Corbin mortise locks had seized from years of summer humidity, so we installed a pair of Schlage deadbolts to meet NYC code and gave each household its own keyway.
Calls are answered by a live person, never a voicemail tree. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back. No paperwork, no arguing.
Our Lock Installation & Rekey Services in East Flatbush
Smart Lock Installation
Smart locks in East Flatbush require more than screwing a keypad to a door. The wooden frames in these 70-100-year-old brick homes swell dramatically during Brooklyn’s humid summers, binding bolts and causing misalignment that fries the motor in poorly fitted units. We measure frame movement, recommend Schlage or Yale smart locks with adjustable backsets, and install them with the seasonal expansion factored in. A typical smart lock installation in East Flatbush runs $220-$380 including hardware and labor.
Rekeying
Rekeying is our most common call in East Flatbush, and it’s rarely straightforward. The legacy mortise cylinders in pre-war homes often have worn pin chambers that won’t accept standard rekey kits. We stock replacement cylinders for Corbin, Russwin, and old Yale hardware, and we can match a new keyway to your existing master key system. Rekeying a single cylinder in East Flatbush typically costs $89-$140; two-family buildings with separate systems for owner and tenant usually run $160-$240.
Key Duplication
Key duplication for East Flatbush’s older locks requires precision cutting machines that handle the non-standard keyways common to mid-century hardware. We duplicate on-site for Schlage, Medeco, and Kwikset, and we can source blanks for discontinued Corbin and Russwin profiles. Key duplication runs $12-$35 per key depending on the blank. For two-family buildings, we code keys so owner and tenant sets are visually distinct - one brass, one nickel, for instance - preventing mix-ups at the door.
Keypad Lock & Biometric Lock Installation
Keypad and biometric locks appeal to East Flatbush owners who want to eliminate key management for tenants or Airbnb units. These installs demand clean, square door prep - a challenge in frames that have settled for decades. We reinforce strike plates, shim misaligned jambs, and select hardware with adjustable faceplates to compensate. Keypad installation runs $180-$320; biometric units with fingerprint readers run $280-$450.

Trusted Brands We Service in East Flatbush
We install and service Schlage, Medeco, and Kwikset hardware from stock carried on every truck, plus we source Abloy and Baldwin for specialized applications. For East Flatbush’s older housing stock, we maintain a parts inventory of Corbin and Russwin mortise components that big-box stores stopped carrying years ago. Most repairs complete same-day because the parts are already in the van. When a 1950s Yale lockset needs a cylinder we don’t stock, we pull from our Brooklyn warehouse and return within 24 hours - no waiting on mail-order parts that leave your door unsecured.
Common Lock Installation & Rekey Problems We See in East Flatbush Homes
- Big-box rekey kits fail on legacy cylinders. Homeowners buy a universal rekey kit from a hardware store, only to find the pins don’t match the worn 70-year-old mortise cylinder, leaving the lock non-functional. The chambers in pre-war Corbin and Russwin hardware are hand-fitted and vary enough that off-the-shelf kits simply don’t seat properly.
- Smart locks jam in swollen summer frames. A tenant tries to install a smart lock on a door that swells in summer, binding the bolt and causing the lock to jam or fail to latch, triggering a lockout. Brooklyn’s humidity from June through August pushes frame expansion past the tolerance of standard smart lock strikes.
- Unlicensed installers skip NYC deadbolt requirements. Unlicensed locksmiths from outside Brooklyn offer cheap installation but ignore NYC DCA deadbolt requirements under Administrative Code §27-2043, resulting in a failed inspection and fines for the owner. Only a licensed NYC locksmith understands the compliance documentation your building inspector will ask for.
- Winter freeze seizes exterior security hardware. The padlocks and roll-down gate locks that many East Flatbush homeowners added to ground-floor entries and windows seize during January freeze-thaw cycles, requiring disassembly or replacement rather than simple lubrication.

FAQs - Lock Installation & Rekey in East Flatbush
It requires a compliant deadbolt on every apartment entrance door in your building, with specific throw length and strike plate standards that differ from suburban requirements in Nassau County or Westchester. If you’re a two-family owner, both your unit and your tenant’s unit need separate, code-compliant deadbolts. We install to this standard on every job and document compliance for your records. Call (877) 664-8139 for a free estimate - we’ll walk through what your building needs.
You can try, but the success rate is low. The mortise prep, frame swelling, and non-standard backsets in pre-war brick homes cause smart locks to jam, misalign, or fail to latch within months. We’ve removed dozens of DIY smart locks that were damaged by bolt binding. We install them to fit the seasonal movement of your specific frame. Call (877) 664-8139 - estimates are free, and we quote the full price before we start.
Brooklyn’s humid summers swell the wooden door frames inside your brick home, compressing the lock cylinder and pin stack against the key. It’s predictable from June through August in East Flatbush’s older housing stock. We can relieve the binding with frame adjustment or recommend a lock with tighter tolerances that tolerates the expansion. Call (877) 664-8139 - we can assess whether it’s a quick fix or a deeper frame issue.
Rekeying changes the pin combination so old keys no longer work - faster, cheaper, same hardware. Replacing swaps the entire lock body, necessary when mortise cylinders are worn beyond rekey tolerance or when upgrading to code-compliant deadbolts under §27-2043. In East Flatbush’s two-families, we often rekey the owner cylinder and replace the tenant’s with a new code-compliant deadbolt. Call (877) 664-8139 - we’ll recommend the right approach for your building after seeing the hardware.
Yes. NYC requires a DCA locksmith license with active enforcement and sting operations - a standard that doesn’t exist just over the Nassau County line. An unlicensed technician can’t legally document code compliance, and if something goes wrong, you have no recourse. Our technicians display DCA license and photo ID at every door. Call (877) 664-8139 - ask us for our license number when you call. We’re glad to provide it.
