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
In a plaza, an office building or a multi-tenant industrial unit, some doors on your floor plan are not yours to rekey. Corridor doors, electrical and mechanical rooms, shared loading doors and the building's fire exits usually sit on the landlord's master system, and a suite entrance may be required to accept the landlord's key as well as yours. The locksmith sorts the openings into two columns before starting: those the lease puts under your control, which get the new plan, and those that stay as they are or need the property manager's say-so. Where a suite door must accept both a tenant key and the building master, it is pinned to do exactly that.
Scene 2
When the plan includes a master, each cylinder is pinned to accept two keys: its own change key and the master above it. Thin master pins sit in the pin stacks so the plug can turn at both the change key's height and the master's; master keying can also create extra, unintended combinations, so the locksmith charts the system to keep those from lining up with someone else's key, and the manager's key opens its whole group and nothing beyond it. A well-built system leaves unused combinations in reserve, so when the business adds a door or a department next year the new cylinder joins the plan without disturbing the keys already in people's pockets.
Scene 3
A rekey touches a few people outside the business, and the handover covers them. If the lease asks for it, the landlord or property manager receives a key to the suite entrance and a note that the locks were changed, which keeps you onside for emergencies and inspections. The alarm monitoring company is given the updated keyholder list, and it is a good moment to change the alarm codes of anyone who no longer works there, since a key and a code usually leave together. Cleaners, the courier with after-hours access and the neighbour who watches the place on holidays each collect their new key against the register like everyone else.

FeesSame any hour
Between tenants is the ideal moment: the departing tenant has handed back their keys, the new one has not yet received any, and the unit is empty for the work. The incoming tenant then starts on keys nobody else has held, and the landlord's own master or emergency key is set up at the same time. Where a lease has ended in dispute, the locksmith asks to see the paperwork before changing locks on a unit that still holds a tenant's goods.
A small-format interchangeable core is a small figure-eight cylinder that slides out of the lever, deadbolt or padlock when a control key is turned, with no tools needed; larger doors sometimes use a large-format core with a different profile instead. A manager keeps the control key in the safe and a few spare cores on hand, so a missing key means the core is swapped in moments and repinned later. For a business with frequent staff turnover, it turns a call-out into a routine.
There is no fixed interval. Rekey on events rather than on a calendar: a key not returned, a lease change, a break-in, a renovation crew finished, or a key count that no longer matches the register. Businesses with a good register and a restricted keyway often go years between rekeys because nothing prompts one. A yearly check of the register against the keys on the hook is the habit that tells you when the time has come.
