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.
For a business running several locations, this service is often less about one broken lock and more about bringing every door onto a single, manageable key or interchangeable-core system. The locksmith surveys what is currently on each door, works out a keying structure the business can actually administer, from a single master down to individual change keys, and replaces mismatched hardware with cylinders built to accept that structure. Keys are cut and logged against the new system, and any hardware still under a fire or egress rule is checked and matched to that rule at the same time.

Scene 1
The last part of the assessment looks past today's problem to how the business expects to manage this door going forward: does staff turnover happen often enough that an interchangeable core, which lets a key holder change the combination without pulling the whole cylinder, would pay for itself in convenience? Does the business want a restricted keyway so blanks cannot be cut at an ordinary hardware counter? These questions shape the specific hardware ordered as much as the door's physical construction does.
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
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.

That is entirely your choice. Some businesses keep old hardware briefly in case a spare part is needed elsewhere on the same system, others prefer it removed from the site straightaway, particularly after a break-in where the damaged pieces are no longer wanted around. The locksmith can leave it with you or take it away, whichever you prefer.
Yes. A restricted keyway limits duplication to keys cut through the manufacturer or an authorized distributor rather than at an ordinary hardware counter, though the exact registration and proof-of-entitlement steps vary by system; a patent-protected keyway adds a further, legally backed layer of control on top of that. This is a common step for a business tightening key control after a lost key or staff turnover.
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.
