Fast, Reliable Lock Installation & Rekey Across East Flatbush
Lock installation and rekeying in East Flatbush costs $95 to $185 for a standard rekey of one to three cylinders, and $180 to $420 for a full mortise lock replacement on the neighborhood’s older brick homes. Most jobs in East Flatbush are completed the same day you call, usually within two to four hours depending on whether we need to source legacy Corbin, Yale, or Sargent mortise hardware. Call (331) 310-8471 and a live dispatcher will give you a firm written price before we ever send a truck. No technician is permitted to change that number at your door. That rule has been in place since 2002.
Why Novak Lock & Security Is East Flatbush’s Preferred Lock Installation & Rekey Company
East Flatbush is not a neighborhood where a generic suburban locksmith survives. The housing stock here was built between the 1920s and 1940s, much of it brick semi-detached and attached two- and three-family homes with solid wood doors cut for full-case mortise locks. That means when you call for a rekey or a lock replacement, we are usually working with hardware that Home Depot stopped stocking decades ago. We carry Corbin, Yale, and Sargent mortise bodies and trim on the truck. Our Lock Installation & Rekey team trains specifically on these legacy formats before they ever touch a cylinder in this neighborhood.
Daniel Novak founded this company on a simple rule: the price quoted on the phone is the price on the invoice. It is Haven Standard Clause 1, and it applies to every job in East Flatbush, whether we are rekeying a single tenant door off Church Avenue or replacing a seized mortise deadbolt near Utica Avenue. Every technician who arrives at your door is background-checked and in uniform. Every job ends with a documented photo record of the work, left with you before we leave. Our reviews from East Flatbush homeowners consistently mention two things: the price did not move, and the tech knew the old mortise hardware without a long pause.
Our Lock Installation & Rekey Services in East Flatbush

Smart Lock Installation
Smart locks on East Flatbush doors present a specific problem: most retrofits are designed for bored cylindrical prep, and your 1930s door has a full mortise pocket instead. We install smart locks that work with the door you actually have, not the door the manufacturer assumes. That often means adapting a Schlage Encode or Yale Assure to a mortise-compatible trim, or installing a smart deadbolt above the existing mortise lock when adding a second bore is acceptable. We will tell you which option preserves the door and which one weakens it. Either way, the price is written before we start.

Keyless Entry
Keyless entry on a two-family East Flatbush house usually means one of two things: a keypad deadbolt on the front door, or a standalone keypad for a common entry. We install both, and we will match the finish to existing Baldwin or Yale trim rather than leaving you with a satin nickel deadbolt over a brass mortise plate. For owner-landlords who live in the upstairs unit and rent the lower one, keyless entry with a new code between tenants can reduce the rekey cycle. But we will also tell you plainly: a keypad does not rekey the lock behind it. You still need the cylinder rekeyed between tenants.

Keypad Lock
Keypad locks in East Flatbush get the same climate stress as every other piece of hardware on these older doors. The salt air and humidity that works through the neighborhood from Jamaica Bay and the Atlantic corrodes internal contacts and battery terminals on cheap keypads within two to three years. We fit marine-grade and stainless keypad deadbolts rated for coated exterior use, and we will tell you which brands hold up on a north-facing door off Flatbush Avenue that never dries out. Installation typically runs $85 to $160 in labor plus the lock, quoted in writing before dispatch.

Biometric Lock
Biometric locks are rare on East Flatbush exterior doors, and there is a reason for that: fingerprint readers fail faster in freeze-thaw humidity cycles than keypads do. We install them where they make sense, which is usually interior unit doors or home offices rather than a front door facing a February freeze. If you want biometric access on your main entry, we will show you the combined deadbolt options that give you a fingerprint reader plus a physical key override. The key override matters in a neighborhood where winter temperatures drop into the teens and anything electronic can slow down.

Trusted Brands We Service in East Flatbush
We are factory-authorized for Medeco, Mul-T-Lock, Yale, and Baldwin, and we carry the legacy Corbin and Sargent mortise hardware that this neighborhood’s original doors demand. That combination is uncommon: most locksmiths stock one or the other, not both. When a 1934 corridor lock off Nostrand Avenue needs a new cylinder and trim, we pull the right mortise body from local stock and rebuild it on site. When you want high-security key control after a tenant dispute, we cut and register Medeco or Mul-T-Lock keys that cannot be duplicated at a hardware counter. The brand decision follows the security problem. The price is written before either option is touched.
Common Lock Installation & Rekey Problems We See in East Flatbush Homes

- Seized mortise cylinders from Atlantic humidity. The pin and tumbler stacks inside exterior lock cylinders corrode over years of salt air exposure, especially on doors facing south and east near the water. The lock still turns with the original key until one day it does not, usually during a cold snap. We disassemble and rebuild the cylinder rather than drilling the lock body.
- Deadbolts thrown out of alignment every winter. Brooklyn’s freeze-thaw cycles move the brick and wood-frame door assemblies on these 1920s and 1930s houses. When the frame shifts a few millimeters, the mortise bolt no longer lines up with the strike plate. You can lift the door and force it, but that wears the bolt. We realign or replace the strike plate and adjust the latch.
- Tenant turnover rekeys that never happened. On a block of two-families near Clarkson Avenue, the pattern repeats: a tenant moves out, the owner-landlord means to rekey, and then a set of old keys shows up in the wrong hands. We rekey the cylinder to new keys the same day and hand the owner a written record of how many working keys exist.
- Original mortise bodies people are told to replace. We hear it regularly: a chain locksmith looked at a 1930s Corbin mortise lock, said the door needed to be bored out or replaced, and quoted a price for a hollow-core door. That is the wrong answer. We service and rebuild the original mortise hardware in place, preserving the solid-wood door and its trim.
Pricing for Lock Installation & Rekey in East Flatbush, NY
Here are the numbers, written plainly. A standard rekey of one to three cylinders in East Flatbush runs $95 to $185, including new keys and the service call. A mortise lock rebuild (disassembly, cylinder replacement, pinning, and reassembly) runs $180 to $320 depending on whether we are sourcing Corbin, Yale, or Sargent trim. Full mortise lock replacement with new hardware runs $280 to $420. Smart lock installation labor is $85 to $160 plus the lock, and we will quote the lock price from current supplier cost, not a padded list. Key duplication runs $4 to $9 per standard key, $15 to $35 for high-security Medeco or Mul-T-Lock blanks, which we cut and register at our facility. Every price is quoted on the phone before anyone is dispatched, and that number is the number on your invoice. There is no call-out surcharge added on arrival. Estimates are free. Call (331) 310-8471.
These ranges reflect East Flatbush’s housing stock specifically: older mortise work takes more labor than a bored cylindrical swap, and legacy hardware sometimes requires sourcing from specialist suppliers. We would rather tell you a real number up front than surprise you at the door.

FAQs - Lock Installation & Rekey in East Flatbush

Yes. We rekey original Corbin, Yale, and Sargent mortise locks in place every week in East Flatbush. The process involves removing the cylinder, disassembling it, cleaning any corrosion from the pin and tumbler stack, replacing the pins to match new keys, and reinstalling the cylinder in the existing mortise body. The door and the 1930s trim stay untouched. A standard mortise cylinder rekey runs $95 to $185, and if the cylinder itself is too far gone, we source a matching replacement rather than drilling the door. Call (331) 310-8471 and describe the lock face; we will tell you what we are working with before we arrive.
It is the freeze-thaw cycle. The brick and wood-frame assemblies on these 1920s and 1940s homes expand and contract with winter temperature swings, and the door shifts a few millimeters relative to the frame. That small shift is enough to take the mortise bolt out of alignment with the strike plate. The fix is usually not forcing the door, which wears the bolt. We realign or replace the strike plate and, in some cases, adjust the hinge geometry so the door hangs true in winter. It is a seasonal issue we see from late November through March across East Flatbush. Call (331) 310-8471 for a written quote on a strike plate realignment.
Rekey, not replace. A rekey changes the internal pins so the old tenant’s keys stop working, and it costs a fraction of new hardware. In East Flatbush’s owner-occupied two-families, where tenant turnover is constant and old keys circulate widely, rekeying between every tenant is the standard practice and the right one. We rekey the cylinder and hand you written documentation of exactly how many working keys exist at the end of the call. If the mortise body itself is seized or failing, we will tell you and quote a rebuild or replacement in writing. Call (331) 310-8471 to schedule a between-tenant rekey; we typically complete it the same day.
Yes, in most cases. We adapt smart locks to mortise prep by using mortise-compatible trim or by mounting a smart deadbolt above the existing mortise lock with minimal drilling, and we will show you exactly where the new bore goes before we make it. On some doors, a full mortise-to-cylindrical conversion is possible, but we will not do it if it weakens the solid-wood door. The honest answer is that some smart locks are not made for these doors, and we will tell you which ones are. Call (331) 310-8471 and describe your door; we will quote the installation in writing before anyone is dispatched.
We fit Mul-T-Lock and Baldwin stainless steel deadbolts for exterior doors in East Flatbush that face sustained humidity and salt air. The original Corbin and Yale mortise bodies were built well, but their cylinders and unprotected trim corrode over decades. A stainless steel deadbolt with a marine-grade finish will outlast a standard brass or zinc unit on a door that never fully dries. We also use corrosion-resistant hardware inside the cylinder, and we will tell you if your existing lock is worth rebuilding rather than replacing. Call (331) 310-8471 for a written quote on a coastal-grade deadbolt replacement.
We carry what this neighborhood’s doors actually need: legacy Corbin, Yale, and Sargent mortise hardware, high-security Medeco and Mul-T-Lock cylinders, and the stainless trim that survives Atlantic humidity. We quote a firm price on the phone, we do not change it at your door, and every job ends with a written record and a photo file. That is The Haven Standard, applied by Daniel Novak and our team since 2002. Call (331) 310-8471 for a free, written estimate on any lock installation or rekey in East Flatbush.
