With over a decade of experience securing offices, retail stores, warehouses, and multi-tenant buildings, our licensed locksmiths deliver fast, reliable service — available 24 hours a day, 7 days a week.
Whether you need an emergency commercial lockout resolved at 2 AM or a planned master key system installation for your entire office building, our team arrives within 15–25 minutes anywhere in Brooklyn. We work with industry-leading lock brands including Medeco, Mul-T-Lock, ASSA Abloy, Schlage, and Yale to ensure your business meets the highest security standards.

We install and replace all types of commercial-grade locks, including heavy-duty mortise locks, cylindrical lever locks, panic bars, and electromagnetic locks. Our locksmiths are certified to install high-security Medeco and Mul-T-Lock cylinders that provide superior pick-resistance and key control for your business. We handle single-door replacements up to full building lock upgrades for offices, retail storefronts, and industrial facilities throughout Brooklyn and Manhattan.
Simplify access control across your entire building with a custom master key system. We design hierarchical key structures that allow building managers to access all doors while restricting tenants and employees to their designated areas only. Our master key systems are ideal for office buildings, apartment complexes, co-working spaces, and retail chains in NYC. Every system includes restricted keyways to prevent unauthorized key duplication.
When an employee leaves, a tenant moves out, or you acquire a new commercial space, rekeying is faster and more cost-effective than full lock replacement. Our locksmiths rekey your existing locks on-site, typically completing an entire office suite in under one hour. We can also set up a new master key hierarchy during the rekey process at no additional charge. Average rekeying cost: $25–$45 per lock.
Protect your business against break-ins, lock bumping, and forced entry with high-security commercial locks. We specialize in Medeco Maxum, Mul-T-Lock MT5+, and ASSA Abloy Protec2 cylinders — the same locks used by banks and government buildings. These locks feature patented key control (keys cannot be duplicated without authorization), hardened steel inserts, and UL 437 certification. Ideal for jewelry stores, dispensaries, financial offices, and warehouses in Brooklyn and NYC.
Ensure your business meets NYC fire code requirements with professionally installed panic bars and exit devices. We install Von Duprin, Sargent, and Dorma Kaba crash bars on commercial doors, including fire-rated assemblies. Our team also handles panic bar repairs, adjustments, and ADA compliance modifications for existing installations. We serve offices, schools, restaurants, and event venues across all five NYC boroughs.
Locked out of your office, store, or warehouse? Our 24/7 emergency commercial lockout team arrives at your Brooklyn or Manhattan location in 15–25 minutes. We use non-destructive entry methods to get you back inside without damaging your locks or doors. Whether it’s a storefront lockout at closing time or an office lockout during a weekend, we are always available. No overtime charges for nights and weekends.
Upgrade from traditional keys to a modern electronic access control system. We install and configure key card systems, keypad entry locks, and smart commercial locks that integrate with your building’s existing infrastructure. Our access control solutions are perfect for co-working spaces, medical offices, and multi-tenant buildings where you need to track entry, set time-based access, and remotely manage door locks. We work with top brands like HID, Kaba, and Alarm Lock.

A master key system allows a single “master” key to open every lock in your building, while individual keys only open their assigned doors. This is essential for building managers, property owners, and businesses with multiple offices or departments. If you manage a commercial building, office suite, or retail plaza in Brooklyn or NYC, a master key system saves time, improves security, and eliminates the need to carry dozens of keys. We design and install custom master key systems tailored to your building’s layout.
We provide commercial locksmith services throughout all five NYC boroughs, with primary coverage in Brooklyn (Brooklyn Heights, DUMBO, Downtown Brooklyn, Williamsburg, Greenpoint, Park Slope, Cobble Hill, Carroll Gardens, Fort Greene, Prospect Heights, Flatbush, Bay Ridge) and Manhattan (Lower Manhattan, Midtown, Upper East Side, Upper West Side).
