Medeco Locksmith in Brooklyn, NY | Novak Lock & Security
We provide independent Medeco locksmith service across Brooklyn, from Crown Heights to Bay Ridge, and the thing that sets our Medeco work apart here is simple: we rebuild and rekey these high-security cylinders inside hundred-year-old mortise lock cases every single week. Brooklyn’s housing stock demands it. Daniel Novak grew up in Astoria and has spent two decades working New York City doors, and the name on the van is the same name on the invoice. Call (331) 310-8471 for a firm price before anyone is dispatched.
Why Brooklyn Residents Choose Us for Medeco Service
Most locksmiths in the five boroughs know Medeco as a brand name. We know it as a pinning system, a side-pin channel, a tailpiece spec, and a keyway geometry. Our techs work on Medeco Classic, Biaxial, M3, and X4 cylinders daily across Brooklyn’s brownstone rowhouses and pre-war apartment buildings, and we also service Medeco in Manhattan. Daniel Novak learned the trade at Queensborough Community College before apprenticing under a retired locksmith who serviced Midtown commercial accounts, and that background means we diagnose a frozen Medeco side pin rather than guessing at it.
We’re an independent Medeco service provider. We are not factory-authorized and we do not claim to be. We source genuine Medeco pins, cylinders, and tailpieces through aftermarket channels and machine our own keys on-site. A factory warranty is not required for us to diagnose, repair, or upgrade your lock. What you get is a written price before work starts, a documented photo record when we leave, and the 365-Day Done Right Promise if something isn’t right.
Common Medeco Locksmith Problems We Solve in Brooklyn

- Salt-air corrosion seizing side pins. Brooklyn is surrounded by water on three sides, and neighborhoods like Coney Island, Brighton Beach, and Bay Ridge get direct Atlantic salt exposure. Medeco’s spring-loaded side pins and check pins corrode faster here than inland, and the key freezes in the cylinder even when the mechanical alignment is still fine. We disassemble, clean, and replace pins rather than telling you to buy a new lock.
- Bent Medeco keys in the side-pin channel. Brooklyn tenants force keys into misaligned antique mortise adapters on old rowhouse doors. Medeco keys have angled cuts in a narrow channel, and forcing a key into a swollen wooden door frame destroys those cuts. We cut new keys and realign the strike plate so the bolt actually seats.
- Failed tailpieces on mortise conversions. Brownstone doors use mortise lock pockets machined into thick wooden stiles. When a Medeco cylinder is retrofitted into a pre-war Corbin or Sargent mortise case, the hardened tailpiece can snap before the cylinder itself would fail. The deadbolt won’t retract, and the tenant is locked out. We extract the broken tailpiece and replace it with the correct Medeco part.
- Binding cylinders from hundred-year-old door dust. In buildings without a top guard plate, Medeco’s spring-loaded side pins foul with the accumulated dust of a century inside the door frame. The cylinder binds gradually until a freeze-thaw shift finishes the job and the lockout happens at 11 p.m. on a Wednesday.
- January freeze-thaw lockouts. Brownstone door frames are old-growth wood, and they swell and shift noticeably through Brooklyn’s winter cycles. Bolts no longer align with strike plates. When that door has a Medeco cylinder, the misalignment puts extra side force on the key, which accelerates pin wear and eventually the key won’t turn at all.
Medeco Service in Brooklyn: What Local Conditions Mean for Your Equipment
Brooklyn’s city-wide Multiple Dwelling Law requires landlords to provide new working locks and keys at tenant turnover. That’s a legal mandate, not a preference. In a borough dominated by two-to-four-family brownstones with three or four tenanted units each, this creates a constant churn of Medeco cylinders through the Lock Installation & Rekey in Brooklyn pipeline. A single Crown Heights rowhouse might have a 1990s Medeco Biaxial mortise on the ground floor, a Schlage B-series deadbolt on the second, and an X4 core on the third. One house call requires three different skill sets and parts inventories before we leave the stoop.
That volume doesn’t exist in Nassau County or Staten Island, where single-family homes dominate and tenant turnover rekeying is rare. What it means for Medeco owners in Brooklyn is this: the locksmith you hire needs to know how to rekey a Biaxial cylinder without factory authorization, rebuild a Corbin mortise case from the 1920s, and cut a master key that turns all three units. We do that work routinely. A landlord called us to a three-family limestone rowhouse on Sterling Place in Crown Heights after a tenant turnover. The ground-floor door still carried a 1990s Medeco Biaxial mortise cylinder with a frozen side-pin spring and a bent tenant key. Our tech disassembled the lock case, extracted the old tailpiece, rebuilt the cylinder with fresh Medeco pins, and cut a new master key that also turned the X4 core on the second-floor door. We left all three units on one master system with iron-strap reinforcement behind the strike plates by dinnertime.
Medeco Models & Products We Service in Brooklyn

We service the full Medeco lineup: Medeco Classic, the original high-security cylinder; Medeco Biaxial, with its patented angled pin system; Medeco M3, which is upgradeable and backwards-compatible with Biaxial; and Medeco X4, the newer high-security platform. We insist on genuine Medeco pins, springs, and cylinders for all repairs. Aftermarket “Medeco-compatible” parts fail catastrophically under key side force and do not maintain UL 437 listing. When a cylinder is too corroded or the side-pin channel is worn beyond wear limits, we recommend replacement rather than a rebuild. But we rekey existing Medeco Classic and Biaxial cylinders whenever the core components are intact. We stock genuine Medeco pins and tailpieces locally for fast Brooklyn turnaround.
Our Medeco work falls into three categories that cover most Brooklyn call-outs: Medeco sales & service for full cylinder replacement or new installation, lock rekey for tenant turnover and lost-key situations, and high security locks for owners upgrading from entry-grade hardware. Each job gets a written scope and a flat price before we start.
Medeco Service Pricing in Brooklyn
Medeco service in Brooklyn typically runs $95 to $185 for a standard rekey of an existing Medeco cylinder, depending on the model and whether we’re cutting new keys or reusing existing ones. Full cylinder replacement with a new Medeco M3 or X4 typically runs $220 to $410 per door, including the cylinder, labor, and new keys. If the job involves rebuilding an antique mortise case, pricing is quoted after we inspect the case on-site because the condition of hundred-year-old internals varies door to door. The price we quote on the phone is the price on the invoice. Haven Standard Clause 1. There is no call-out surcharge added on arrival. Call (331) 310-8471 for an exact quote. Estimates are free.

FAQs - Medeco Locksmith in Brooklyn
Yes. We rekey Medeco Biaxial cylinders using genuine Medeco pins sourced through aftermarket channels and our own key-cutting equipment. You do not need the original dealer keys or a factory authorization for us to rekey the cylinder. If the core components are intact, we rebuild and rekey it same-day. Call (331) 310-8471 and we’ll give you a firm price before we’re dispatched.
Yes, it’s one of the most common Medeco failures we see in Brooklyn between January and February. Old-growth wooden door frames in brownstones swell and shift through freeze-thaw cycles, and the bolt no longer aligns with the strike plate. That misalignment puts side force on the Medeco key, which binds the side pins. We realign the strike plate or adjust the mortise case, then rekey or rebuild the cylinder if the pins are worn. Call (331) 310-8471 and a Brooklyn Emergency Locksmith answers live, 24/7.
Yes. Since Medeco M3 cylinders use a restricted keyway, a lost key means we rekey the cylinder to a new key code, cut new keys on-site, and leave you with a documented record of the new keying. This is standard tenant turnover work under the Multiple Dwelling Law, and we handle it across Park Slope, Crown Heights, and the rest of Brooklyn every week. Call (331) 310-8471 for a flat per-cylinder price in writing before we start.
Yes. The Atlantic salt air in waterfront neighborhoods like Coney Island, Brighton Beach, and Bay Ridge accelerates corrosion of Medeco’s side pins and check pins compared to inland neighborhoods like Flatbush or East New York. The key freezes in the cylinder even when the lock’s mechanical alignment is still fine. Regular cleaning and pin replacement prevents most failures. If your Medeco has started binding near the waterfront, call (331) 310-8471 for an inspection quote.
Yes, in most cases. We retrofit Medeco cylinders into existing pre-war mortise cases from Corbin, Sargent, and Yale using the correct tailpieces and adapters. We don’t drill new holes unless the case is beyond repair, and we always tell you before we touch the door. Call (331) 310-8471 and we’ll quote the retrofit price over the phone.
