B&G Locksmith sits inside B&G Hardware at 210 Roebling St in Williamsburg. We handle commercial locksmith work for small shops, restaurants, offices, landlords, and building supers across Brooklyn and the five boroughs - walk in, call ahead, or get us out to your location the same day.

What does a commercial locksmith actually handle for Brooklyn businesses?

Commercial locksmith work covers everything from a single door lock to a building-wide access plan. Here is what we do most often for businesses in Williamsburg, Greenpoint, Bushwick, Bed-Stuy, East Williamsburg, and Downtown Brooklyn:

• Commercial lockouts - You are locked out of your shop or office and need it open fast. We get there and pick or bypass the lock without damage when possible, then rekey or replace so you are not using the same lock a stranger may have a key to.
• Lock changes and rekeys - New tenant, fired employee, or lost keys mean it is time to rekey. We rekey Schlage B-series, Medeco Maxum, Mul-T-Lock MT5+, and most standard commercial cylinders. A full rekey on a multi-door office typically runs $80 to $200 depending on the number of cylinders.
• High-security locks - We install Medeco M3, Mul-T-Lock MT5+, and ASSA Abloy cylinders for businesses that need restricted keyways. These locks resist picking and drilling and the keys cannot be duplicated without authorization. Expect to pay $150 to $400 per door installed for high-security hardware.
• Master key systems - We design and build master key systems for landlords, supers, and multi-unit commercial buildings. A 10-door master key setup using Schlage commercial cylinders typically runs $300 to $700 parts and labor.
• Rolling gate locks and slam locks - Common across Bushwick and East Williamsburg storefronts. We replace worn cylinders, install new slam locks, and rekey existing hardware. Rolling gate lock replacement usually runs $100 to $250 depending on the type.
• Panic bars and exit devices - We install and service Von Duprin 98/99 and Falcon 25 series exit devices for commercial buildings with fire egress requirements.
• Access control and intercoms - We install keypad and fob-based access control using Alarm.com and Butterfly MX intercom systems for commercial tenants and building owners.
• Key cutting and duplication - Walk up to the counter at B&G Hardware and get commercial keys cut while you wait. We stock Schlage, Kwikset, Medeco, and most common commercial blanks.

How do master key systems work and what do they cost in Brooklyn?

A master key system gives different people access to different doors while one key opens everything. A building super carries the master. Each tenant has a change key that opens only their unit. A grand master key can sit with the property manager and open every door in the building.

We design these systems from scratch or expand existing ones. The process starts with a site walkthrough or a conversation about your door count and access levels. Then we specify cylinders, cut the key series, and install everything. We use Schlage L-series mortise locks and Best SFIC (Small Format Interchangeable Core) cylinders for larger buildings where you want to swap cores without a locksmith on site every time.

Realistic cost guide for Brooklyn commercial clients:

1. Small retail shop, 3 doors, master plus two change keys: $180 to $350
2. Office suite, 8 doors, tiered master key system: $450 to $900
3. Multi-unit residential or mixed-use building, 20 doors with grand master: $900 to $2,500 depending on cylinder grade and hardware condition

We stock hardware at the shop so most small-to-mid builds get done in one visit. No waiting on orders to ship.

Why choose B&G Locksmith over a phone-dispatch locksmith for your Williamsburg business?

Most locksmiths in Brooklyn are dispatch-only operations. You call a number, someone routes a tech to you, and you have no idea who shows up or what they are carrying in their van. B&G Locksmith is the opposite. We are a real storefront at 210 Roebling St. You can walk up to the counter, look at the hardware, and talk to the person doing the work before you commit to anything.

That matters for commercial clients because the stakes are higher. You are not just locking a bedroom door. You are protecting inventory, staff, equipment, and customer data. We have been doing this work in Williamsburg and across Brooklyn long enough to know what holds up on a busy Bedford Ave restaurant door versus a Greenpoint warehouse gate.

We also carry stock. When a rolling gate slam lock fails on a Saturday morning in East Williamsburg before your shop opens, we are not waiting on a parts order. We pull it off the shelf and get you open.

For commercial service anywhere in Brooklyn or the five boroughs, call B&G Locksmith at (347) 699-9268. Walk-ins welcome at 210 Roebling St, Williamsburg.

Frequently asked questions

Can you rekey my business locks without replacing them?

Yes. As long as the lock cylinder is in decent shape, we rekey it on the spot. We carry replacement pins for Schlage, Kwikset, and most Medeco cylinders right at the shop on Roebling St. Rekeying is almost always cheaper than replacing, and we will tell you honestly if replacement makes more sense.

Do you work on rolling gate locks in Brooklyn?

Yes. We repair and replace rolling gate locks and slam locks across Brooklyn, including Bushwick, Bed-Stuy, and East Williamsburg. We stock common parts so most jobs get done the same visit. If your gate cylinder is worn or you lost the keys, call us before the next time you need to open that gate.

How fast can you respond to a commercial lockout in Williamsburg?

For businesses near our Roebling St shop we typically arrive within 30 to 45 minutes. Outlying Brooklyn neighborhoods and other boroughs may take a little longer depending on the time of day. Call (347) 699-9268 and we will give you an honest arrival estimate right on the phone.
