Commercial locksmith service covers business door hardware and key control: master key systems, heavy-duty lever sets and mortise locks, exit devices, door closers, storefront hardware, and rekeying at employee turnover. When you call, we connect you with an independent local locksmith pro experienced in commercial work. The pro surveys your doors, recommends hardware by duty grade and code requirements, and quotes you directly before any work begins. We never quote prices ourselves.
The pro typically starts with a walk-through of your doors, because commercial work is a system, not a single lock. They document each opening: hardware type, condition, duty grade, and how it fits your operations and life-safety requirements. From there the work falls into a few categories. Installation and repair covers lever sets, mortise locks, deadbolts and deadlatches, exit devices on egress doors, door closers, storefront hardware on aluminum-and-glass doors, and auxiliary items like cabinet, desk, and padlock hardware. Key control covers rekeying at turnover, designing and expanding master key systems, and managing restricted keyways that resist unauthorized copying. Access control bridges into keypads, standalone electronic levers, and credential-based systems for businesses moving beyond metal keys. Throughout, the pro pays attention to egress: exit doors must let people leave freely under fire and building codes, and reputable pros will not install hardware that traps occupants. Every phase is quoted directly before work begins.
A master key system is a planned hierarchy of keys. Individual keys open only their assigned doors, while master keys open groups of doors, and a top-level key can open everything, letting an owner carry one key while each employee carries access matched to their role. A well-designed system maps to your organization: the office manager's key opens offices but not the server room, cleaning staff reach common areas only, and the owner's key opens all of it. Businesses outgrow ad-hoc keying quickly; once you have more than a handful of doors or any distinction between who may go where, a master system replaces the fat keyring and the guesswork. Good systems are designed with expansion room so future doors and departments fit without rekeying everything, and they are documented in records the owner controls. Pairing the design with a restricted keyway adds accountability, since key copies can only be made through authorized channels with your sign-off.
Commercial hardware is specified by duty grade under the ANSI/BHMA standard, which rates locks Grade 1, Grade 2, and Grade 3 based on cycle life, strength, and durability testing. Grade 1 is the commercial benchmark, built for high-traffic doors that cycle hundreds of times a day; Grade 2 suits lighter commercial and heavy residential duty; Grade 3 is light residential hardware that has no business on a commercial entry. Beyond grade, hardware divides into classes by function and construction: cylindrical lever sets that install in a bored opening and serve most interior doors; mortise locks whose case fits into a pocket in the door edge, favored for heavy-use and institutional openings; exit devices, the push-bars required on many egress doors; deadlatches and paddle hardware for narrow-stile storefront doors; and electrified variants of each for access control. Matching class and grade to each opening's traffic, code role, and abuse level is exactly the judgment a commercial pro brings to the survey.
Rekeying is the routine hygiene of commercial key control. Trigger it when an employee with keys departs on anything less than perfect terms, when a key is lost or unaccounted for, when you move into a space previously occupied by another tenant, after a contractor project where keys circulated, and on a periodic schedule if your turnover is steady. Rekeying keeps the hardware and changes only which keys work, so it is far less disruptive than replacement. Other common triggers: doors that slam or drift open as closers wear out, exit devices that stick or fail to latch, storefront locks that no longer catch as aluminum doors sag, lever sets loosening under daily abuse, and break-in damage needing same-day repair. Compliance moments matter too, since an insurance review, fire inspection, or lease requirement may surface hardware that must be corrected. A standing relationship with one local pro who knows your doors makes each of these a quick call rather than a project.
Authority comes first: the pro will want to deal with an owner, officer, or property manager who can approve changes to the building's key control, so have that person available and bring documentation such as a lease or business record if you are new to the pro. Prepare a door list before the survey, noting problem doors, high-traffic openings, and rooms with distinct access needs like stock rooms, offices, server closets, and cash areas. Gather what exists of your current key records: which keys open what, who holds copies, and any paperwork from a previous master key system, since expanding an existing documented system differs from starting clean. Know your constraints, including lease clauses about door hardware, landlord approval requirements, and any fire-inspection findings. For rekeying at employee turnover, decide the new key distribution in advance so the pro can cut the right quantities once. Finally, share your hours of operation, since some work is better scheduled outside business hours.
The most common is installing residential-grade hardware on commercial doors. A Grade 3 lever from a home-improvement aisle fails in months under commercial traffic, while hardware rated Grade 1 under the ANSI/BHMA standard is engineered for exactly that duty. A second is losing control of keys: copies handed out without records, no rekey after departures, and standard keyways that anyone can copy at a kiosk, which together mean the business no longer knows who can enter. Third is neglecting egress: chaining or double-locking exit doors to stop theft creates a life-safety violation that inspectors and, far worse, emergencies will expose; a pro can solve the security concern with compliant hardware. Businesses also ignore failing door closers until a slamming door destroys the lock, defer maintenance on storefront hardware until the door will not latch overnight, and buy access-control gadgets before fixing the mechanical basics underneath. Finally, many wait for a lockout or break-in to establish a locksmith relationship instead of starting with a survey.
| Factor | Why it matters |
|---|---|
| Hardware class and duty grade | Commercial jobs are specified by hardware class, cylindrical lever, mortise lock, exit device, storefront deadlatch, and by duty grade under the ANSI/BHMA standard, where Grade 1 is the high-traffic commercial benchmark. Heavier classes and grades involve more substantial parts and more installation labor per opening. |
| Master key system design and scale | A master key system's scope grows with the number of doors, access levels, and future expansion room designed in. Extending an existing documented system is a smaller job than designing one from scratch, and undocumented legacy systems may need decoding before any new work can proceed. |
| Restricted keyways and key control | Patented, restricted keyways prevent unauthorized copying and add accountability, but their controlled blanks, authorization procedures, and record-keeping involve more administration than open keyways. That control is the point, and it applies to every future key the system issues. |
| Rekey versus replace across the facility | Sound commercial hardware gets rekeyed at turnover, while worn levers, failing closers, and sagging storefront hardware are better replaced. A facility survey usually mixes both paths door by door, and the split between them shapes the total scope the pro quotes. |
| Code and egress requirements | Egress doors must release freely under fire and building codes, which constrains hardware choices on those openings to compliant exit devices and functions. Bringing a noncompliant door up to code can add hardware and labor, but it is not optional, and reputable pros will not install around it. |
| Scheduling around business operations | Work on entry doors and high-traffic openings often needs to happen before opening, after closing, or overnight so the business keeps operating, and emergency response to break-ins or failed locks happens on no notice at all. Independent pros set their own rates for off-hours work and state them directly. |
Locksmith Call Now publishes no prices — the independent pro you're connected with quotes the job directly to you before any work begins.
Commercial work involves heavier-duty hardware classes, mortise locks, exit devices, storefront hardware, Grade 1 lever sets rated under ANSI/BHMA, plus system-level concerns like master keying, restricted key control, and egress code compliance. Residential work centers on individual doors; commercial work manages a building.
Rekey whenever a departing employee held keys and you cannot fully account for copies, and always after a contentious exit. Businesses with steady turnover often adopt a periodic rekey schedule or a restricted keyway system so unauthorized copies cannot be made in the first place.
Yes, that is a master key system. Individual keys open assigned doors, group masters open departments, and the top-level key opens all. A pro designs the hierarchy around your floor plan and roles, documents it, and leaves expansion room for future doors.
Not if it impedes egress. Fire and building codes require that occupants can exit freely, and hardware that traps people creates liability and inspection failures. A commercial pro can address the theft concern with compliant exit devices and alarmed or controlled hardware instead.
We never quote prices. Scope depends on hardware class and grade, door count, master key system design, restricted keyway administration, code requirements, and scheduling around your operations. The independent local pro surveys your facility and quotes you directly before any work begins.
