You have just signed the lease on a unit the previous tenant ran for a decade. The landlord handed over three keys, the back door wears a padlock nobody can open, and nobody can say how many front-door keys are still out there.
Losing a master key exposes every door it opened, and a commercial rekey brings that exposure back to zero. The locksmith first works out which level the missing key sat at: a single change key affects one or two cylinders, while a master reaches every lock in its group. Only the affected cylinders are repinned, which keeps the rest of the system intact and the response proportionate. Where a keying chart exists the work is precise; where the chart has been lost, the visit begins by reading and recording the existing cylinders so the new plan starts from facts rather than memory.

Scene 1
The keying plan is a picture of how the business runs, so the assessment asks who goes through which door on a normal day. Front-line staff need the customer entrance and perhaps the stockroom; supervisors add the office; the owner and the bookkeeper hold the cash room; the IT contractor reaches the server closet and nothing else. Out of that conversation come the key groups: doors keyed alike so one key covers a role, doors keyed differently where separation matters, and whether a master for the owner earns its place. The plan also names anything left out on purpose, so the chart shows both what changes and what stays.
Scene 2
Where the business already runs on interchangeable cores, the door hardware never comes apart. The control key goes into the figure-eight core, turns a few degrees, and the whole core slides out of the lever or padlock in one piece. A freshly combinated core goes in the same way, the operating key is tried, and that door is done. The old cores travel back to the bench to be repinned for another opening or held as spares. This is what makes cores so well suited to businesses with steady turnover: a single control key, kept in the manager's safe rather than on a ring, is all it takes to change a lock.
Scene 3
You leave the visit with a one-page chart that lists every opening by name, the key group it belongs to, the code stamped on that group's keys and how many were cut. It is written for the manager, not the locksmith: the stockroom is called the stockroom, and a glance shows that key group B opens the office and the cash room and nothing else. The bitting details that a locksmith needs to add a cylinder later are kept separately and securely. Pin the chart inside the manager's cupboard, keep a copy off site, and it becomes the reference every future key question is answered from.

Every old key that operated a cylinder included in the plan will stop working, and the locksmith proves it by trying old keys at each door before leaving. Old keys keep working only at openings you chose to leave alone, which are written on the chart so there is no confusion. If a master key existed, it is tested too, since a forgotten master is the most common way an old key stays alive.
Yes, if the cylinders share a keyway or can be fitted with ones that do. Keying everything alike is popular with small shops because staff carry one key and spares are simple. The trade-off is that one key then opens the cash room as readily as the front door. Many businesses choose a middle path: the doors everyone uses on one key, the sensitive rooms on another, and an owner's master that opens both.
Yes. The narrow stile of a storefront door houses a screw-in mortise cylinder secured from the edge, and it unthreads, is repinned and screws back in like any other. What the locksmith watches is the cam: it has to suit the hook or deadbolt mechanism inside the door and sit at the correct depth, or the bolt throws short. Weather-facing cylinders showing salt wear are pointed out so you can decide on replacement.
