- The call
- A new tenant moved into the unit next door, and the property manager just found three different cylinders on three doors, none of them cut to the same key.

An 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.
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.

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
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.
Scene 3
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.

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.
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.
Yes, and it is a common request from businesses running more than one location. The locksmith works out a keying structure, a master for management, sub-masters per site or department, and individual change keys, then supplies cylinders across the locations that accept that structure. Keeping a record of the whole structure in one place is what makes it manageable afterward.
