Lock Change and Rekey Service in Williamsburg, Brooklyn

If you just moved into a Williamsburg apartment, lost a key, finished a tenancy, or simply want to know who has access to your home or business, a lock change or rekey is the right first step. B & G Locksmith handles both services for renters, homeowners, landlords, supers, and commercial tenants across Brooklyn and the five boroughs - from Greenpoint and Bushwick to Bed-Stuy, East Williamsburg, and Downtown Brooklyn. You can walk into our counter inside B & G Hardware at 210 Robeling St, or call us out to your door.

What is the difference between a lock change and a rekey, and which one do you need?

A rekey keeps your existing lock hardware in place. A locksmith removes the cylinder and replaces the internal pin stack so that every old key stops working and a fresh key cut is the only one that opens the lock. It costs less than a full replacement because the hardware stays. Rekeying makes sense when your lock is in good shape - no wobble, no wear, no damage - and you just need to invalidate old keys after a move-out, a breakup, or a lost key situation.

A lock change means the entire lock comes off and a new one goes on. That is the right call when:

• The current lock is a builder-grade or hollow-core cylinder that offers little real security
• The hardware is worn, loose, or has been forced before
• You want to upgrade to a higher-security or smart lock
• The door has been kicked in or tampered with

For Brooklyn landlords and building supers, we handle both scenarios across multiple units and can key all locks alike so one master key covers the building.

Which lock brands and models does B & G Locksmith work with in Williamsburg?

We stock and install hardware from the brands most common on Brooklyn doors, and we carry many of them on the shelf at B & G Hardware so there is no waiting on an order.

• Schlage B60N and B62N deadbolts - the workhorse for residential doors across Williamsburg and Greenpoint brownstones. ANSI Grade 1 rated, solid brass cylinder.
• Medeco Maxum and Biaxial deadbolts - high-security cylinders with patented keyways. Good choice for landlords who want restricted key duplication so tenants cannot copy keys without authorization.
• Kwikset SmartKey (re-key yourself series) - popular in rental units. We can rekey these in under five minutes or replace them entirely if the SmartKey mechanism has been worn down.
• Mul-T-Lock MT5+ and Interactive+ - drill and pick resistant cylinders used on commercial doors and high-value Bed-Stuy and Downtown Brooklyn properties.
• Yale Assure and Schlage Encode smart locks - keypad and app-controlled locks that work well for short-term rentals and small businesses on the Williamsburg waterfront corridor.

If you walk into B & G Hardware at 210 Robeling St, you can look at the hardware in person before you commit. That is something a phone-only locksmith dispatch cannot offer.

How does the lock change or rekey process work when you call B & G Locksmith?

The process is straightforward whether you come to us or we come to you.

1. Walk-in at 210 Robeling St: Bring your cylinder or existing key. We assess the lock at the counter, pull the right hardware or cut the right key, and send you home ready to go - often in under 30 minutes.
2. On-site appointment: We come to your Williamsburg, Brooklyn, or five-borough address. We inspect the door, frame, and existing hardware before recommending a rekey or replacement. We do not upsell you on a new lock if a rekey is all you need.
3. Multi-unit and commercial jobs: Landlords and supers can schedule a building walk-through. We map out every cylinder, quote the job by door count and lock grade, and can key all units to a master key system so building staff have one key and tenants have individual keys.

We also cut duplicate keys on site for Schlage, Kwikset, Medeco, Mul-T-Lock, and most restricted keyways - no trip to a separate hardware chain needed.

Frequently asked questions

Is rekeying as secure as replacing the lock?

Yes, if the lock hardware itself is in good condition. Rekeying changes the internal pins so old keys stop working completely. If the lock is worn, damaged, or low-grade, a full replacement gives you better security.

How long does a lock change or rekey take?

Most single-door jobs take 20 to 40 minutes on site. If you walk into B & G Hardware at 210 Robeling St, we can often handle it right at the counter while you wait.

Can I get all my locks keyed alike so one key opens everything?

Yes. Keying alike is a standard service we do on Schlage, Kwikset, Medeco, and most other brands. It works on apartments with multiple entry points or small businesses with several doors.
