Commercial Rekeying
A break-in overnight took the cash float and a staff member's bag with her work keys inside it.
In plain words
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.
How the visit goesThe manager's key ring went missing somewhere between the bank and the car, and the master on it opened every door in the building. Until the cylinders are changed, whoever finds it is holding the run of the place.

How the visit goes


A walk of every door and lock
The locksmith walks the premises with you and lists every opening that should be in the plan: the customer entrance, the receiving door, offices, stockroom, cash room, server closet, the mailbox, cabinets, and any padlocks on gates, compounds or roll shutters. Each lock is identified by type, since a mortise cylinder in an aluminum storefront door, a key-in-lever set on an office, a rim cylinder on a back door and an interchangeable core in a stockroom each come out and go back in differently. The keyway and the maker's mark are noted, and the condition of each cylinder is checked, so the list from the walk is what the quote and the work are built on.
Cutting and marking the new keys
Keys are cut to the new combinations on a code machine rather than traced from another key, so every copy is exact and the tenth key fits as cleanly as the first. Each key is stamped with a short code that means something only on the keying chart; the business name, the address and the word for the door it opens stay off the metal, so a lost key gives nothing away. Keys are counted out by group, tagged, and listed against the names of the people who will carry them. Where the plan uses a restricted keyway, the blanks are drawn against the authorization letter, and that letter is filed with the chart for future orders.
Exits that still open the way they must
Rekeying changes who can come in; it never changes how people get out. Every exit door and every door on the way to one is left opening from the inside with a single motion and no key. On a door with a panic bar, the outside cylinder simply controls entry, and the bar keeps working exactly as before. Once the locksmith has finished, walk the exit routes yourself, push each bar and turn each thumb-turn, and make that walk a habit at the start of every season so a new deadbolt or a helpful padlock never creeps onto an exit.

Commercial Rekeying
What affects the quote
Documentation and register
A keying chart, a key register and stamped codes on every key are part of a proper commercial rekey, and the quote names the paperwork so it is never skipped.
After-hours or split visits
Work done after closing, before opening or split across two visits to suit trading hours costs the same amount as a single daytime block. The exact figure is confirmed on site once the number of cylinders and the keying plan are known.
Distance to the premises
Travel to the site is part of the call-out, and a unit in a downtown plaza and one at the end of a rural industrial road are different trips.
What to have ready
- Which doors, if any, belong to the landlord or a shared corridor?
- Can you gather every existing key so they can be read on site?
- Which staff need to open which doors on a normal day?
Commercial Rekeying: questions
QuestionsHow often should a business change its keys as a matter of 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.
How long should we set aside for a commercial rekey?
It depends on the count and the mix. A shop with a front door, a back door and a stockroom is a short visit; an office suite with a dozen lever sets, a master key plan and a mailbox takes a good part of a day. Interchangeable cores are the shortest of all, since they are swapped rather than repinned on site. The locksmith gives a time estimate at the assessment, once every cylinder has been counted.
What happens with our fire exit doors and panic bars?
The outside cylinder on an exit door controls entry only, and it can be rekeyed like any other. The inside stays as it must: one push or one turn, no key, no special knowledge, on the exit door itself and on any door on the way to it. A locksmith will not add a keyed device to the inside of an exit, and will point out one if it already exists.
