Brooklyn businesses need a locksmith who understands more than a deadbolt. Brooklyn Locksmith & Doors handles the full range of commercial security work: lockouts, lock replacements, master key systems, panic bar installation, storefront door repair, and electronic access control. We work on restaurants, offices, retail shops, warehouses, and multi-unit residential buildings across every Brooklyn neighborhood.
What types of commercial locks and hardware do you install and service?
Commercial hardware is not residential hardware. The brands, grades, and mechanisms are different, and choosing the wrong product for a high-traffic door can mean frequent failures and security gaps.
We install and service:
- High-security cylinders from Medeco, Mul-T-Lock, and ASSA Abloy. These resist picking, drilling, and key duplication without authorization.
- Grade 1 mortise locks including Schlage L-Series and Best 9K, standard on office and retail doors that see heavy daily use.
- Panic bars and exit devices from Von Duprin and Detex, required by NYC fire code on many commercial egress doors.
- Electronic access control including Kisi, Salto, and HID keycard readers for offices that need audit trails and remote management.
- Master key systems that let building owners or managers carry one key while tenants or staff have limited access.
A coffee shop in Williamsburg and a warehouse in Bushwick have very different security needs. We assess the door type, traffic volume, and threat level before recommending hardware.
How do you handle storefront door repair and commercial door problems?
A broken storefront door is not just a security problem. It is a business interruption. Customers notice a door that sticks, a lock that jams, or a frame that is visibly damaged. In Brooklyn's older commercial stock, door frames shift, mortise pockets crack, and exposed hardware corrodes faster than property owners expect.
Common commercial door jobs we handle:
- Storefront door closers that slam or fail to latch, including LCN 4040XP and Norton 7500 series replacements
- Aluminum storefront door frame repair after break-in or impact damage
- Roll-up gate lock replacement for manual and motorized gates in Bay Ridge and Crown Heights
- Door reinforcement with strike plate upgrades and wrap-around guards on wood frame doors common in Park Slope and Brooklyn Heights brownstones converted to commercial use
- Push bar realignment and panic bar replacement to keep exit devices code-compliant
Most storefront door repairs are completed in a single visit. If parts need to be ordered, we secure the door before we leave.
What is a master key system and does your business actually need one?
A master key system organizes locks into a hierarchy. A grandmaster key opens every lock in a building. A master key opens a subset, such as all offices on one floor. An individual change key opens only one lock. This structure is standard in commercial buildings, property management, and any business where multiple people need different levels of access.
You need a master key system if:
- You manage a multi-tenant commercial building and need to access any unit without carrying a full ring of keys
- You have staff with different security clearances who should not have access to every area
- You are consolidating multiple buildings under one key system, common for property managers working across Williamsburg and Crown Heights portfolios
We design and build master key systems using Schlage, Medeco, and Mul-T-Lock cylinders. All key cuts are controlled and documented. Unauthorized duplication is prevented at the cylinder level with restricted keyways.
If your current key system is ad hoc, meaning different locks from different brands installed over the years with no plan, a master key rebuild is usually straightforward. We assess your existing hardware, identify what can be rekeyed into the system, and replace only what needs to go.

Frequently asked questions
Can you rekey a commercial building after an employee leaves?
Yes. Rekeying is the fastest way to cut off access after a staff change. We rekey Schlage, Medeco, and Mul-T-Lock cylinders and can update your master key system the same day.
Do you work on storefront gates and roll-up doors?
We do. We repair and replace locks on manual and motorized roll-up gates across Brooklyn, including in Bushwick and Crown Heights where gate security is a common request.
How quickly can you respond to a commercial lockout?
We offer fast response across all Brooklyn neighborhoods. Call (347) 357-0985 and a technician will be dispatched directly to your location.
