High-Security Locks and Door Hardware for NYC Businesses
Commercial doors take abuse a residential door never sees: hundreds of cycles a day, delivery carts, and the occasional attempted break-in. We install Medeco and Mul-T-Lock high-security cylinders on storefront doors, office suites, and back-of-house entries, hardware built to resist picking, bumping, and drilling, with restricted keys that can't be copied at a corner shop. We also handle the supporting cast: heavy-duty deadbolts, mortise locks, keypads, and the exit devices and closers that keep a busy door working instead of failing mid-shift.
Lease Turnover? Rekey Before the New Tenant Moves In
Every lease that ends leaves keys unaccounted for, former employees, old vendors, the previous tenant's contractor. Rekeying changes the pins inside your existing locks so old keys stop working, usually without replacing any hardware. It's the fastest, cheapest way to reset access on day one of a new lease.
Property managers use us for the same reason at scale: when a commercial unit turns over, we rekey the suite, update the building master if there is one, and hand over a clean set of keys with a count you can file.
Exit Devices, Access Control, and After-Hours Service
Egress doors need hardware that lets people out in one motion while keeping the wrong people from walking in. We install and repair panic bars, alarmed exit devices, and door closers, and we install Comelit intercoms and access control for buildings moving past metal keys at the front door. Because we run 24/7, the work happens when your business is closed, a storefront lock swap at midnight beats one during the lunch rush, and an after-hours break-in gets boarded with new locks the same night.
Which Doors a Commercial Job Actually Involves
Business owners usually call about one door and then discover the job is four. A typical Manhattan or Brooklyn commercial space has a street entrance, an interior suite or vestibule door, a back or service door onto an alley or corridor, and a door to a stock room, an office or a comms closet. Each one takes different hardware.
The street door is generally an aluminum storefront entrance, and the narrow vertical rail on those takes a specific lock body and closer. A residential deadbolt does not fit and should never be forced into one. Interior suite doors in an office building are usually fire rated, which limits what may be cut into them in the field. Back and service doors are where an exit device is most often required, and where we most often find one that has been chained shut, which is both a safety problem and a violation waiting to happen.
When you ask for a quote, say how many doors and what each one is. That single sentence is the difference between a real number and a guess.
What Separates Commercial Hardware From Residential
The honest answer is cycles. Commercial hardware is graded for how many times it will be opened and closed, and a busy storefront does in a short time what a house door takes years to do. Grade 1 is the commercial-duty tier, Grade 2 sits below it, and Grade 3 is residential. Fitting Grade 3 hardware to a busy storefront is a common way a business ends up paying for the same door twice.
The same logic applies to closers and hinges. A door propped and shoved by someone carrying boxes all day will wear out a light closer, and a continuous hinge running the full height of the door spreads that load along the whole edge instead of onto three points. If a quote does not say what grade it is fitting, ask, because that is usually where a cheap number comes from.
It also decides your rekey options later. Commercial cylinders on a master key system can be rekeyed to a new plan across every door at once. Mixed residential hardware bought door by door usually cannot.
The Compliance Side Nobody Quotes For
Two things get commercial spaces written up, and both are lock and door questions rather than paperwork questions.
The first is egress. An exit route has to open from the inside without a key, without special knowledge and without tight twisting or grasping. That is why an exit device exists, and why a thumb-turn deadbolt on a required exit door is a problem even though it feels secure. Padlocks and chains on a rear exit during business hours are the version of this that gets a business shut down.
The second is the fire-rated assembly. Interior suite doors, stair doors and many service doors are certified as a whole unit, and field modifications to them are limited to what the standard and the manufacturer's listing allow. Drilling a rated door for new hardware without checking can mean the door has to be relabeled by the testing lab, which is a site visit and a bill rather than a plug.
Neither of these shows up on a cheap quote, and both of them show up on an inspection.
Commercial Locksmith Work by Borough
The trade is the same everywhere, but what comes up changes with the building stock. In Manhattan it is mostly office suites and narrow-stile storefronts, with building management holding a master key that has to keep working. In Midtown specifically it is tenant fit-outs, exit devices and key control across a floor.
In Brooklyn the retail strips bring roll-down gate locks and older wood doors alongside aluminum ones. In Queens there is more standalone commercial property with its own service yard and rear entrance. Wherever the space is, the business lockout and office lockout pages cover the emergency side.

Common Questions
Should I rekey or replace my locks when a tenant leaves?
Rekey when the hardware is in good shape, it makes old keys useless at lower cost. Replace when locks are worn, damaged, or you want an upgrade to high-security cylinders. We'll tell you honestly which one your doors need.
Can you do the work outside business hours?
Yes. We operate 24/7 across all five boroughs, so lock changes, rekeys, and hardware installs can happen overnight or on weekends without interrupting your business.
Can one key open everything in my building?
Yes, that's a master key system. We design hierarchies where a master opens every door while individual keys open only their own. Restricted keyways keep unauthorized copies out of circulation.
What does commercial locksmith work cost?
Every job gets a transparent quote before work begins, with no hidden fees. Scope drives price: a single rekey is simple, a building-wide system is quoted door by door.
What grade of lock should a storefront have?
Grade 1, which is the commercial-duty tier. Grade 2 sits below it and Grade 3 is residential. A busy entrance can see as many open-and-close cycles in a month as a house door sees in a year, so residential hardware on a storefront is the usual reason a business pays for the same door twice.
Can we put a deadbolt on our rear exit door?
Not one that needs a key or special knowledge to get out. A required exit has to open from the inside in a single motion, which is what an exit device is for. Chaining or padlocking a rear exit during business hours is the version of this that gets a business shut down, and it is worth fixing before anyone inspects it.
Our building manager holds a master key. Does a lock change break it?
It will unless the work is planned around it, and most commercial leases require that master to keep working. Tell whoever is quoting that a building master exists before the job starts. Keying a new cylinder into an existing master plan is routine when it is known up front and a nuisance when it is discovered afterwards.
