- The call
- You let a part-time employee go on Friday. The shop key is on a ring in their apartment, or their car, or a friend's kitchen, and on Monday morning the register and the stock room open with it.

The spare under the planter by the side door is gone. Everyone in the family swears they did not take it, the planter has clearly been shifted, and you have no idea how long ago that happened.
How much a lost key matters depends on what was lost with it. A ring that dropped into a lake on a canoe trip tells nobody where it fits, so the rekey is a tidy precaution. A ring taken with a wallet or bag that carried your address is a different story: someone now holds both the key and the door it opens, and the rekey comes first. The locksmith asks about this on the phone, says plainly which situation you are in, and schedules the visit accordingly. The work is the same either way, and so is the outcome: a key nobody else has.

Lost Keys — Same-Visit Rekey · Thornhill

Scene 1
Every cylinder on the list gets a close look while it is still in the door. The keyway shape and the maker's stamp tell the locksmith which pin kit fits and whether the keys can be cut on the van. The feel of the plug with a working key, if one exists, says whether the pins and springs are healthy or tired. Corrosion on the face, a wobbly plug or a key that needs a jiggle points to a cylinder that will benefit from cleaning or replacing while it is out. A homeowner-rekeyable cylinder, recognisable by its small reset slot beside the keyway, calls for a different tool and gets noted.
Scene 2
Restricted and patented keyways rekey in much the same way, with more parts and a little more care. A high-security cylinder's own elements, a sidebar's finger pins, a rotating element or another system-specific part, are reset to the new key's profile alongside the ordinary pins, and the finished plug is checked before refitting. Key blanks for these systems are issued through whatever authorised channel that system uses, a letter, a registered account, a dealer agreement, or sometimes a key card; bring whatever credential you were given. The reward is that copies of the new key can only be made through that same channel, one of the stronger kinds of key control a household can have.
Scene 3
Where a tenancy, a condominium or a commercial lease is involved, the visit ends with a plain written note: which cylinders were rekeyed, how many keys were cut, who received them, and the key code if the property keeps a register. Tenants pass it to the landlord along with the landlord's set of new keys, keeping the paper trail on both sides current. Condominium managers can update the building's key record. A small business can file it with the lease. It is a few lines that save a long conversation later.

Your suite door is generally the one you can act on, and it may sit on a building master system, so the locksmith plans the rekey so the master still operates while the old change key stops working. Lobby doors, the parking gate, amenity rooms and the mailroom belong to the corporation; report a lost fob or key for those to the property manager, who deactivates or reissues it. The locksmith can help sort which is which.
Just the lock, and the door it is fitted to. A rekey works on the cylinder itself: the locksmith opens it, fits a new set of pins matched to a fresh key, and the old key stops working the moment that is done, whether or not it ever turns up again. Knowing roughly how the old key looked, cut on both edges, a chip on the head, a certain brand, can still help identify which cylinders in the house shared that key.
It is your call, and it is a reasonable one either way. A key lost on your own property is unlikely to be picked up by a stranger, but it will surface in the spring thaw, and until then you are trusting a guess about where it lies. Many households rekey anyway for the certainty, and because the visit also lets them put every door on one key while the locksmith is there.
