Treasure Coast Locksmith provides commercial lock installation services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Commercial lock installation uses Grade 1 BHMA/ANSI A156 hardware for durability in high-traffic applications. Main categories: mortise locks (strongest, pocket-fit in door edge), cylindrical locks (bored into door face, easier to install), and commercial deadbolts. Brands: Schlage, Corbin Russwin, Best, Sargent, Yale.
Commercial lock installation is different from residential work. Grade 1 durability, code compliance (NFPA, ADA, Florida Building Code), proper master key integration, and documentation for property managers all matter. The hardware is more expensive but lasts 10-20+ years under commercial use.
The main commercial lock categories: cylindrical locks (bored into door face through two holes, easier to install, Grade 1 models rated for million-plus cycles), mortise locks (fit into a pocket cut in the door edge, strongest configuration, used in high-security applications), and commercial deadbolts (1-inch throw minimum, hardened inserts, heavy-duty strikes).
Treasure Coast Locksmith installs commercial locks for offices, retail plazas, warehouses, medical facilities, schools, and institutional buildings. We carry Grade 1 hardware from major commercial manufacturers and integrate locks with existing master key systems.

Commercial lock types, specifications, and selection
Commercial locks fall into three main categories based on installation method and construction. Understanding the differences helps specify correct hardware for each application.
Mortise Locks: The strongest commercial lockset design. Lock body fits into a pocket (mortise) cut in the door edge, about 5-6 inches deep and 4 inches tall. Strong, durable, and feature-rich - mortise locks include multiple functions (latch, deadbolt, auxiliary lock) in one body.
Installation requires deeper door preparation than cylindrical. Common on high-security, high-traffic, or prestige applications. Schlage L-series is the dominant North American mortise lock.
Cylindrical Locks: Also called "bored locks" - the door is bored with a cross-bore (2-1/8" hole through the door face) and edge-bore (1" hole through the door edge). Lock installs through the cross-bore, with latch through the edge-bore. Easier to install than mortise, good durability at Grade 1 level, and the standard commercial lockset for most applications.
Schlage ND-series, Corbin Russwin CL3300, Best 8K, Yale 5400LN, Sargent 11 Line are common Grade 1 cylindrical locks.
Commercial Deadbolts: Separate from the main lockset, deadbolts provide additional security on commercial doors. 1-inch minimum throw for Grade 1. Hardened inserts in the bolt prevent sawing.
Heavy-duty strikes with long screws into frame backing. Often paired with cylindrical locks for full security on commercial doors.
BHMA Grading: BHMA/ANSI A156 grades commercial hardware Grade 1 (highest) to Grade 3 (lowest). Grade 1 commercial cylindrical locks: 1,000,000+ operational cycles. Grade 1 deadbolts: 250,000 cycles with hardened bolt.
Grade 2 is light commercial or heavy residential. Grade 3 is residential quality with no commercial application. All serious commercial work should use Grade 1.
Interchangeable Cores (SFIC/LFIC): Some commercial systems use removable cylinder cores. Best Access Systems dominates the small-format interchangeable core (SFIC) market. Advantage: rekey without removing the lock from the door - just swap cores.
Common in schools, hospitals, and large facilities managing many locks. Requires specific lock bodies accepting SFIC cores.
Master Key Integration: New commercial lock installations often must integrate with existing master key systems. This means cylinders keyed to the existing system pattern, appropriate cylinder types (restricted vs standard), and documentation for the master key plan. We integrate with existing systems and can also design new master key plans for buildings starting fresh.
Specification Selection: Common lock functions - passage (no lock, just latch), privacy (push-button lock for restrooms), storeroom (always locked outside, free egress inside), classroom (key locks/unlocks from outside), entry (key and lever lock from outside), office (lever locks with button or key), communicating (unlocked from one side, key from other). Match function to application.
