Commercial Rekeying in Old Mill
The 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.

Taking over a commercial unit is the moment to make the locks yours. The keys handed across at signing are only the ones the previous occupant remembered; cleaners, suppliers and former staff may still carry others. Rekeying every cylinder your lease gives you control of gives you a clean start on day one, with keys cut for your team and a chart of which door each one opens. The locksmith also clears up the odds and ends that come with a new lease: a padlock with no key, a mailbox lock seized since the last tenant. You open knowing exactly who can get in.
How the visit goesThe office has been reshuffled twice since the locks were last touched. Reception can open the server room, the warehouse crew has a key to accounting, and the chart that once explained who could open what has not been seen since the move.

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.

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.

Storefront hardware ready for the salt
Cylinders on a street-facing door live a hard life: slush, salt spray from the sidewalk plough and a dozen freeze-thaw swings a winter. Each cylinder handled during the rekey is cleaned and dressed with the lubricant approved for that model, a dry graphite, PTFE or specified liquid lubricant applied sparingly, since too much graphite can gum a cylinder just as oil traps grit. Keep it that way with a puff of the same lubricant each autumn and a wipe of the key before it goes in on a slushy morning. A set screw snugged, a cam aligned and a bolt that throws fully are part of the handover, so the rekeyed door also locks more cleanly than it did before.

What affects the quote
- 1
Interchangeable cores versus repinning
Cores swapped with a control key are the shortest work on site, while cylinders that must come apart on a bench take longer. Supplying spare cores for the manager to hold is priced as its own line.

Several locations
Rekeying two or three sites onto one keying plan means travel between them and a chart that spans buildings, quoted per site plus the shared design work.

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
Is a restricted keyway worth it for a business?
A restricted keyway uses blanks that only the locksmith or authorized source can obtain, released against whatever that key-control program requires, a signed letter, card, signature record or factory authorization naming who may order keys. Hardware stores and kiosks have no blanks, so copies are far harder to get without your say-so. It costs more per key than a standard keyway and is most valuable where keys pass through many hands, such as retail with part-time staff, shared premises or anywhere the count of copies has drifted before.
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.
Can the work be done while we are open?
Yes, and many businesses prefer it. The locksmith works one door at a time, finishing and testing each before starting the next, and leaves the main entrance until a quiet moment or until after closing. Doors staff are using are done last and their new keys are handed over first. Where a business would rather nobody sees the work, an early morning or after-hours window is arranged instead.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
Older homes tend to have had many hands on their doors: owners, tenants, tradespeople, family. A locksmith visiting such a house pays attention to who holds keys now, and rekeying or a keyed-alike set often matters more than any new hardware.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Shared entrances mean fobs, intercoms and buzzers alongside conventional locks. A locksmith can service the mechanical side of those doors and advise on how the fob system and the cylinder work together when management asks.
