Commercial-Grade Lock Replacement
Head office wants every branch keyed alike under one system, and half the locations are still running whatever lockset the original contractor happened to install years ago.
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 goesAn inspection report flagged the rear exit as needing hardware that opens with one motion and no key, and that door currently has an ordinary keyed knob on the inside.

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.
Matching the cylinder to the business's key system
The cylinder installed is the one agreed during the assessment: keyed into an existing master or grand-master system, set up as a new interchangeable core the business can rekey itself later, or cut to a restricted keyway that limits who can order duplicate keys. Where several doors are being brought onto one system in the same visit, cylinders are combinated so a single key or a defined set of keys operates every door that is supposed to share access.
One key system instead of a patchwork
Where the visit brought hardware onto a shared master or interchangeable-core system, the business now has one coherent structure instead of a different cylinder on every door. A master key opens what it is supposed to, sub-master and change keys are limited to their own doors, and the key-control log reflects exactly who was issued what. The next time a lock needs attention, whoever handles it can read that log rather than guessing at what system, if any, the previous hardware belonged to.

What affects the quote
Number 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.
Key-control documentation
Setting up or updating a written key-control log, recording who holds which key and which doors share a system, is a small but distinct task the quote can name separately from the physical hardware work.
Site 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.
What to have ready
- What kind of door is it: solid, hollow-metal, wood, or aluminum storefront?
- Is the door part of a fire separation or a marked exit route?
- What is currently installed: a knob, a deadbolt, a mortise lock, or an exit device?
Commercial-Grade Lock Replacement: questions
QuestionsWhat happens to keys held by former employees or contractors?
Once a cylinder is replaced or rekeyed, any key that was not reissued for the new combination simply stops working on that door. This is the direct answer to a key that walked out with someone who left the business, and it is worth doing across every door that key used to open, not only the one that prompted the call.
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.
Why would my business need panic or exit hardware?
Once a space holds enough people, or handles a high enough hazard, its exit doors need to open with a single motion and no key, which is what panic or exit hardware provides. It is not a preference; it is a function tied to how many people the space is built to hold and what is happening in it.
