Commercial Rekeying
Two people left over the summer and the keys they handed back came up one short. Nobody is sure whether the missing key was for the front door, the stockroom or both, and the sign-out sheet stopped being filled in a year ago.

A commercial rekey is planned around the trading day. The locksmith agrees a window, often after close or before opening, and works door by door so the premises is never left without a locking entrance. Cylinders come out, are repinned at a bench in the van or on a counter, and go back in; interchangeable cores are simply swapped for freshly combinated ones. Each door is tried with both new and old keys before the next is started. New keys go to whoever opens up in the morning, and a written chart of doors and key groups stays with the manager.
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
Reading the keys that already exist
Before deciding anything new, it helps to understand the old. Gather every key the business can find, including the ones with faded tape labels, and the locksmith reads them against the cylinders on the walk. Some will turn out to be duplicates of each other, some will belong to hardware that was replaced years ago, and some may operate doors nobody expected them to. Hardware-store copies stand out by their blanks and by the way they wear. This reading shows how far the key count has drifted and whether an old master still exists, and it lets the new plan retire everything found in the drawer rather than only the keys anyone remembered.

Retiring the old keys
The job is finished when the old keys are proven dead, not when the new ones work. At every rekeyed opening the locksmith tries a sample of the old keys, including the master if one existed, and confirms that each one enters the keyway and turns nothing. The collected old keys are then cut through with snips in front of the manager and can be handed back as scrap or taken away. Any door deliberately left on its original key is written on the chart in plain words so nobody assumes it changed. That last check is what turns a day of brass work into a genuine reset of who can open the business.

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.
In the van
- Mortise cylinder set screws and cams
- Commercial pin kit
- Key gauge and decoder
- Dry graphite or PTFE lubricant
- Interchangeable cores and control key
What affects the quote
- 1
Restricted keyway
Moving to a patented, restricted keyway means new cylinders or cores rather than a repin of the old ones, and the blanks themselves carry a higher price than standard keys.
- 2
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.
- 3
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.
Same fees day, night or weekend.
Commercial Rekeying: questions
What do you do with the old keys?
They are gathered, tested at each rekeyed door to confirm they no longer work, and then cut through so they can never be used or copied. You can keep the pieces or the locksmith takes them away. Any old key that still operates a door you chose to leave unchanged is handed back and noted on the chart, so it is clear which keys remain live and which are scrap.
Will rekeying affect our alarm system or card readers?
Mechanical rekeying leaves electronics alone: alarm panels, card readers and keypads keep their codes and credentials. What changes is the list of people holding keys, and it is worth updating the alarm company's keyholder list and retiring the codes of anyone who has left at the same time, since keys and codes usually walk out together. Where a door has both a card reader and a keyed override, the override cylinder is rekeyed with the rest.
Can padlocks, cabinets and the mailbox go on the plan too?
Yes. Gate, cage and shutter padlocks that accept repinning can share the back-door key, and the locks on filing cabinets, drawers and display cases can be grouped so the people who work at them carry a single key while the manager holds a separate one. Mailbox cylinders are small and are usually swapped for new rather than repinned. Everything is entered on the chart, so one document covers the whole premises.

What the census means at the door
47%
Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
50%
A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).
Where housing is mixed, the same street can hold a solid wood front door, a steel townhouse door and a metal-clad suite door. A locksmith fits each with hardware suited to its construction, so every neighbour ends up with a door that locks properly.
