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.
How the visit goesThe electric strike buzzes the moment the receptionist presses the release button, but the door still needs a shoulder to get past the latch, as though the two pieces were never matched.

How the visit goes
- 1
Checking for a fire rating or an exit requirement
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.

Fitting the new lock body or lockset
The new hardware is installed into the existing prep, with the lock body or lockset, strike and any reinforcing plate seated so the door closes without binding. On a narrow-stile storefront door, the hookbolt or deadlatch is aligned so it engages the keeper across its full travel rather than catching on one edge. On a mortise-prepped door, the case is fitted so the trim sits flush and the spindle and cylinder line up with the existing holes cut for them.

Ready for the next security decision
With current hardware and an accurate key-control record in place, the business is better positioned for whatever comes next: adding a location to the master key system, upgrading a single door to an interchangeable core so staff can rekey it without a service call, or answering an insurer's or landlord's question about what security is on a given door. None of that requires starting from scratch, because the replacement visit leaves behind hardware and documentation that a future decision can build on directly.

What affects the quote
- 1
Timing relative to a lease or renovation
Work scheduled around a tenant turnover, a renovation, or a building-wide upgrade across several units can be planned and quoted as a coordinated project rather than a series of separate calls.
- 2
Grade and duty rating of the lock
Hardware built for higher cycle counts and rougher daily handling costs more than a lighter-duty equivalent, and the right grade for a busy delivery door is not the same as for a quiet interior office.
- 3
Number of keys cut and issued
Keys are counted individually into the quote. A small office needing a handful of keys is a smaller line item than a multi-shift operation issuing keys to a large staff roster.
Same fees day, night or weekend.
Commercial-Grade Lock Replacement: questions
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.
Who should hold the master key once the system is set up?
That is a decision for the business, not the locksmith, but the general practice is to limit master keys to the smallest number of people who genuinely need building-wide access, and to log who holds each one. Sub-master and change keys can then cover departments, shifts or single doors without every key holder carrying access to everything.
How do you know if my door is part of a fire separation?
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.

What the census means at the door
71%
Older homes. About 71% of homes in St. Catharines were built in 1980 or earlier, according to the 2021 Census.
Basement and side entries on older homes were often fitted long after the house was built, with whatever lock was on hand. Bringing those doors up to the standard of the front entry, and onto the same key, is a common and satisfying job.
56%
A mix of homes. Single-detached houses make up about 56% of homes in St. Catharines (2021 Census).
Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
