The key to the office entrance turns with almost no resistance now, and some mornings the deadbolt does not fully retract until someone jiggles the handle and tries the key again.
Commercial-grade lock replacement swaps hardware that is worn, damaged, mismatched or simply not rated for a business door with hardware built for that duty: a mortise lock body, a heavy cylindrical lockset, or a narrow-stile lock or hookbolt for an aluminum storefront door. The locksmith reads the door's construction, the traffic the opening takes, and any key or access-control system already running before choosing a replacement. New hardware is keyed into that existing system rather than left to stand on its own, so one business ends up with one coherent set of locks instead of a patchwork of whatever was fitted door by door over the years.

Commercial-Grade Lock Replacement · Burlington

Scene 1
Some commercial doors are part of a fire separation or a required exit route, and that status changes which hardware is legal to install on them. The locksmith looks for a fire label on the door and frame, checks whether the opening serves an assembly space or a high-occupant-load area that calls for listed, push-type release hardware, and confirms whether the door is required to close and latch on its own. None of this is guesswork; it is read directly off the door, its label, and the building's own occupancy information.
Scene 2
The existing lock, cylinder and strike come out without enlarging the door's mortise pocket or bore, since a clean prep is what lets the new hardware seat correctly. Any hardware that was previously mismatched to the door, an incorrect backset or a strike screwed in at an angle, is noted so the business understands why the last repair may not have held. The old hardware is set aside for the business to keep, dispose of, or use as a reference for other doors still running the same outdated lockset.
Scene 3
For a narrow-stile or glass storefront door, the finished job means the hookbolt or deadlatch engages fully across its travel every time, without the shoulder-check that a worn or mismatched lock used to need. Staff closing up for the night can throw the lock once and trust it caught, and the business is no longer relying on a habit of double-checking a door that should simply work. The hardware's finish is also suited to public-facing use, holding its appearance under daily handling.

The door and frame usually carry a small metal label stating the assembly's rating, and the building's own fire safety plan or a previous inspection report will identify which doors are part of a fire separation. If a label is missing or unreadable, that is worth raising with your building's fire safety plan holder before hardware is chosen, since it changes what can legally go on the door.
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.
A home lockout or residential rekey is usually about one door and one household's keys. Commercial-grade lock replacement more often involves a system, several doors, a master key structure, and sometimes a fire or exit rule the door has to satisfy, so the assessment, the hardware selected and the record kept at the end are all built around managing that wider structure rather than a single lock.
