Commercial Locksmith Services for NYC Businesses
Security failures cost NYC businesses thousands every year — through break-ins, unauthorized access, and compliance violations. ASK Locksmith has been securing commercial properties across the five boroughs for over 38 years. We understand NYC building codes, fire egress requirements, and the specific hardware challenges of older commercial buildings.
Master Key Systems
A properly designed master key system gives every user exactly the access they need — nothing more, nothing less. Managers hold master keys that open all doors; employees hold change keys that open only their area. We design, install, and document master key systems for offices, multi-unit residential buildings, hotels, and retail properties using Mul-T-Lock, Medeco, Corbin Russwin, and Sargent hardware.
Panic Bar & Exit Hardware
NYC Fire Code requires panic hardware (crash bars) on most commercial exit doors. We install and service Von Duprin, Falcon, and Sargent panic bars — including rim-mounted, mortise, and vertical rod configurations for double and single doors. We also handle fire-rated door hardware that must meet both security and egress requirements.
Commercial Rekeying
Staff turnover creates ongoing access control risk. We handle full building rekeying projects with minimal disruption — scheduling off-hours work when needed and providing a master key hand-off schedule for property management. For buildings that can't go offline, we rekey floor by floor or section by section.
Commercial Lock Repair & Replacement
High-traffic commercial locks wear out faster than residential hardware. We repair and replace mortise locks, cylindrical locks, exit devices, and closers for offices, retail spaces, restaurants, and multi-tenant buildings. We carry stock for most major commercial brands and can often complete same-day.
How It Works
Site Assessment
We visit your property, evaluate all entry points, existing hardware, and access requirements. For master key systems, we map every door and user group before recommending a design.
Proposal & Scheduling
We provide a written quote covering all hardware and labor. Work is scheduled to minimize disruption — after-hours and weekend slots available for occupied buildings.
Installation & Documentation
We install, test every door, and provide complete key management documentation — including key assignment records and cut cards for your files. All work is NYC code compliant.
Commercial Locksmith FAQ
-
Cost depends on the number of doors, lock hardware grade, and complexity of the key hierarchy. A basic system for a small office starts in the hundreds; a full building installation with high-security hardware runs into the thousands. We provide a detailed written quote after the site assessment.
-
Yes. We schedule commercial work around your operations — evenings, weekends, and overnight for buildings that can't close during business hours. After-hours rates apply and are included in your quote.
-
NYC Fire Code generally requires panic hardware on exits for Assembly (A), Business (B), and Mercantile (M) occupancies above a certain occupant load. The specific requirement depends on your building classification and occupancy. We assess your building and can advise on compliance.
-
Yes — and we recommend doing it promptly after any key departure. We can rekey specific doors or the entire building depending on the key holder's access level. If you're on a master key system we manage, we can add and remove keys with your authorization.
