Locksmiths for Commercial Locksmith Services

Why Commercial Door Hardware Is Its Own Trade

Most homes use light cylindrical locks. Commercial buildings run on heavier gear, and the difference matters when something breaks.

• Mortise locks fit a rectangular case into a deep pocket in the door edge and can combine a latch, a deadbolt, and several functions in one body - which is why they dominate older offices and schools.
• ANSI/BHMA grades rate durability: Grade 1 is built for constant public traffic, Grade 2 for lighter duty, Grade 3 for homes. A Grade 3 lever failing on a busy entry is a mismatch, not bad luck.
• Narrow-stile storefront doors - the aluminum-and-glass type - use slim deadlatches and hookbolt deadbolts because a standard lock body will not fit the frame.

Naming your door type when you call speeds up everything that follows.

Master Key Systems and Interchangeable Cores

Commercial keying is about control. A master key system lets one key open every door while individual keys open only assigned rooms; it works by adding extra pin splits, called master wafers, inside each pin tumbler cylinder.

Small format interchangeable cores (SFIC) go further. The figure-eight-shaped core lifts out of its housing with a special control key, so cores can be swapped in seconds instead of taking locks apart. Buildings with steady staff turnover standardize on SFIC for exactly this reason.

Restricted keyways add key control: the blanks are not openly sold, so keys cannot be copied at a kiosk. If unauthorized duplication worries you, ask about restricted options.

Exit Devices, Door Closers, and Life-Safety Rules

Doors people escape through are regulated hardware. Building and fire codes generally require that occupants can exit in a single motion - no key, no special knowledge.

• Panic bars (exit devices) open when pushed anywhere across the bar. Many include dogging, which holds the latch retracted so the door works push-pull during business hours.
• Electric strikes release the latch electrically for buzz-in entry while the inside handle always opens freely.
• Door closers control swing speed and force so fire doors actually latch; a slamming or drifting door is often a closer valve issue, not a lock problem.

Never chain or wedge an exit device shut to secure a door - that creates a genuine life-safety hazard.

Planning the Work: Repair, Rekey, or Upgrade

A commercial locksmith typically takes one of three paths. Repair fits when a case, spindle, or latch is worn but the platform is sound. Rekeying changes which keys work without replacing hardware - the right move after turnover or a lost master key. Upgrading makes sense when residential-grade hardware is failing under commercial traffic or you want keyless entry. Hardware and labor vary by lock type, door material, and the number of openings, so a clear description of your doors is the most useful thing you can bring to the call. Describe what is failing, confirm the service can help, and then schedule - call (916) 913-5080 to get started.

Frequently Asked Questions

What is a small format interchangeable core, and why do offices use them?

An SFIC is a figure-eight-shaped core that slides out of its housing when a control key is turned. Swapping a core takes seconds and no disassembly, so a door can be rekeyed the moment a key goes missing. One spare set of pinned cores lets a facility respond to turnover fast, while ordinary cylinders must be taken apart and repinned.

Can a door with a panic bar still be locked from the outside?

Yes. Panic bars control egress, not entry. Outside access comes from trim - a keyed lever, a pull with a cylinder, or an electric strike tied to a keypad or card reader. Inside, the bar must always open with one push. Many exit devices also have dogging, which holds the latch retracted so the door acts as a push-pull during open hours and relocks when dogging is released at night.

Do we need new locks every time an employee leaves?

Usually not. Rekeying changes the pin stacks inside the existing cylinders so old keys stop working, which is faster than replacement and keeps your hardware. The exception is a lost master key: because a master opens many doors, every cylinder it operated should be rekeyed or have its core swapped. A locksmith can assess whether your system needs a simple rekey or a rebuilt master key chart.
