Commercial-Grade Lock Replacement in Mount Pleasant
The kitchen delivery door gets shouldered open more than a hundred times a shift, and lately the latch slips past the strike plate instead of catching it on the first push.
Commercial-Grade Lock Replacement
In plain words
A business door rarely fails the same way a house door does, because it opens far more often and often has to satisfy a fire or egress rule a home door never faces. Replacement starts by identifying what the opening actually is: a mortise-prepped steel door, a narrow-stile aluminum storefront, a fire-rated door that needs listed hardware, or an exit serving enough people that code calls for panic-style release. The locksmith fits hardware built for that specific opening, connects it correctly to any electric strike or access-control wiring already present, and hands over keys cut and logged to the business's own system.
How the visit goesOvernight someone forced the back door, and the cylinder face is scarred, the metal around the strike has pulled loose from the frame, and the latch no longer sits flush.

How the visit goes
Looking at how the opening is actually used
A door's traffic shapes which hardware belongs on it. A staff entrance opened a handful of times a day tolerates lighter-duty hardware than a delivery door shouldered open on every shift, and a customer-facing storefront door needs a finish and function that hold up under public use. The locksmith asks how often the door opens, who uses it, and whether it is propped, wedged or held open in daily practice, since a door habitually held open needs hardware and a closer arrangement that account for that use rather than fighting it.
Selecting hardware built for this opening
With the assessment complete, the locksmith orders hardware to match: a mortise lock body for a mortise-prepped door, a heavy cylindrical lockset for a standard bored door, or a narrow-stile lock or hookbolt for an aluminum storefront. Where the door is part of a fire separation or a required exit, the hardware chosen is listed for that rating and function rather than a general-purpose substitute. Grade and finish are matched to the traffic the door takes, so a heavily used delivery door gets hardware built for that duty rather than the lightest option available.
Fire and exit requirements satisfied, not just noted
Where the door forms part of a fire separation or a required exit route, the new hardware is listed for that use and the door has been tested to confirm it still closes and latches on its own. Any push-type release hardware installed to meet an occupant-load threshold has been checked across the whole route it serves, not just at the one door where the call started. The business leaves with an opening that satisfies the condition that triggered the work, rather than a lock that merely looks similar to what was there before.

What affects the quote
Same fees day, night or weekend
1Keying complexity
A single stand-alone cylinder is the simplest keying job. A master or grand-master structure spanning multiple doors, departments or locations takes more planning and more cylinders to combinate correctly, and that planning is part of the quote.
2Number of doors involved
One entrance is the simplest case. Bringing several doors, or several branch locations, onto matching hardware or one key system in the same engagement is priced across the whole set rather than door by door in isolation.
3Site access and building type
A ground-floor storefront is the simplest case to reach and work on. A unit inside a larger building with its own access rules, or a site requiring coordination with building management, can add steps the quote takes into account.
Commercial-Grade Lock Replacement: questions
Can you install a restricted or patented keyway?
Yes. A restricted keyway limits duplication to keys cut through the manufacturer or an authorized distributor rather than at an ordinary hardware counter, though the exact registration and proof-of-entitlement steps vary by system; a patent-protected keyway adds a further, legally backed layer of control on top of that. This is a common step for a business tightening key control after a lost key or staff turnover.
Do you match hardware to my building's existing key system?
Yes, that is usually the first decision made. The locksmith checks whether your doors already run on a master or grand-master system, an interchangeable-core setup, or a restricted keyway, and orders replacement cylinders that slot into whichever structure you want to keep or move to. Bringing a new door onto an existing system is generally simpler than starting that door on its own.
What makes a lock 'commercial-grade' rather than a residential one?
Commercial-grade hardware is built for far higher cycle counts and rougher daily handling than a home lock ever sees: heavier internal components, a lock body and strike designed to take repeated forceful use, and often a rating tied to an industry grading system that measures cycles and impact resistance. A residential deadbolt fitted to a busy business door tends to wear out well before its time because it was never built for that volume of use.
