Commercial Rekeying
A break-in overnight took the cash float and a staff member's bag with her work keys inside it. The glass is being replaced this morning, but the key that opened the door yesterday will still open it tonight unless the cylinders are changed.

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 goesYou 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.

How the visit goes

- 1
Which doors are the landlord's
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.

Door by door, never a gap
The sequence agreed at the assessment is followed on the day. The locksmith finishes one opening entirely before beginning the next: cylinder out, repinned, refitted, tested with both the new key and the old, and locked again. Only then does the next door come apart. The main entrance is usually left for last and done while someone from the business is present, so there is never a moment when the premises has a door that will not lock. Staff who are working during the visit are handed their new key before the door they use is changed, and a short note goes to anyone off shift about where to collect theirs.

A keying chart in plain language
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.

What affects the quote
- 1
Landlord and base-building coordination
Suite doors that must accept both your key and the landlord's master, or work that needs the property manager on site, add coordination the quote allows for.
- 2
Padlocks, cabinets and mailboxes
Small locks add up. Each padlock repinned to the door key, each cabinet keyed alike and each mailbox cylinder replaced is listed on its own so you can decide what to include.
- 3
Cylinders that need replacing
Where a worn, corroded or low-grade cylinder is better replaced than repinned, the new part is added for that door alone, and the locksmith points it out before the work begins.
Same fees day, night or weekend.
Commercial Rekeying: questions
What is a keying chart and why does it matter afterwards?
A keying chart is a plain list of every opening, the key group that operates it, the code stamped on those keys and the number issued. Months later it lets you answer exactly which doors a missing key opened, and it lets a locksmith add a new door to the system without changing anything else. Keep it with the key register, somewhere locked, with a copy off site.
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.
Will every old key stop working once you are done?
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.

What the census means at the door
25%
Newer homes. About 25% of homes in Whitby were built in 1980 or earlier, according to the 2021 Census.
Recent builds often have steel or fibreglass entry doors rather than solid wood. They resist warping and take hardware well, and a locksmith fitting a deadbolt or reinforced strike works with the door's construction so screws bite into something solid.
70%
Mostly houses. Single-detached houses make up about 70% of homes in Whitby (2021 Census).
A detached house gives a locksmith room to work: full access to both sides of every door, hinges and frames included. Repairs and upgrades can be thorough, from the front deadbolt to the gate latch, with nothing off limits.
