- The call
- 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.

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.
Where a home lockout is mostly about getting one door open again, a commercial lock replacement is mostly a decision about a system: how this one door's hardware fits into every other lock the business already manages. The locksmith examines the existing keying, whether cylinders are standard, interchangeable-core or restricted, and whether other doors should be keyed the same way as this one. New hardware is chosen to match the door's fire rating and occupant load where those apply, installed without altering the door's existing prep, and finished with keys cut, tested and recorded in the business's own key-control log.

Commercial-Grade Lock Replacement · Thornhill

Scene 1
Before any hardware is opened up, the locksmith confirms who is speaking for the business: an owner, a property manager, or a staff member the account recognizes as authorized to order and pay for the work. On a multi-tenant building this also means confirming which doors belong to which lease. This step exists for the same reason a home lockout starts with identification: a business's security is only as good as its record of who was allowed to change it, and a clear authorization at the start keeps that record clean.
Scene 2
On a door required to close and latch on its own, the new hardware is installed and the closer adjusted so that behaviour still happens after the work is done: the door swings shut, the latch engages, and nothing about the new lock lets it be secured open in daily use. On an exit route where listed push-type hardware is required, the entire route from that door to the outside is checked so the new hardware fits the same standard as the rest of the path rather than becoming the one mismatched link in it.
Scene 3
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.

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.
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.
Often, yes, particularly with an interchangeable-core system where the core is designed to be swapped without removing the lock body from the door. Where the lock body itself is worn, damaged or of a grade that no longer suits the door's traffic, replacing the cylinder alone would leave the underlying problem in place, so the locksmith says which option actually fits the situation found.
