- 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.
When a key disappears, cutting yourself another copy solves the wrong half of the problem. You can get in again, but so can whoever finds the original. A same-visit rekey turns that around: the locksmith works through each cylinder the missing key operated, fitting new bottom pins on a conventional lock or resetting a homeowner-rekeyable one through its own procedure, and refits the lock to the door. The lost key still slides into the keyway but no longer lifts the pins to the right height, so it turns nothing. You leave with fresh keys cut on site and the same locks you already had.

Lost Keys — Same-Visit Rekey · Vaughan

Scene 1
Rekeying suits hardware in sound condition, and most cylinders on a house qualify. The locksmith flags the exceptions while the list is being made: a plug worn oval by decades of use, a cylinder packed with salt and grit from a side door that faces the driveway, a knob lock so light it offers little resistance, or a keyway that no longer has blanks available. For those, a replacement cylinder or a complete new deadbolt keyed to match the rest is proposed as its own item, so you decide door by door. The aim is that every cylinder leaving the visit on a new key is one that will keep turning well for years.
Scene 2
On a conventional pin-tumbler cylinder, with it on the bench, the plug is turned slightly and a follower is slid in behind it so the springs and top pins stay in the housing rather than scattering. The plug comes out and the old bottom pins are tipped away. The new key is cut first, then a pin whose length matches each cut is dropped into the corresponding chamber, checked flush with a gauge, and the loaded plug is guided back under the follower. The plug should turn with a light, even feel and no catch. If it drags on one chamber, that pin is sized again before anything goes back on the door.
Scene 3
Rekeying is a repeatable act, and after this visit you know what triggers it. Moving into a new home, because previous occupants and their helpers may hold copies. A contractor or tenant leaving without handing a key back. A separation or a change of roommates. A ring lost with anything that names your address. Manufacturers list exactly these moments, and a household that treats them as routine stays in control of its doors for decades with the same hardware. The locks on the door today can be repinned many more times; only the small pins and the keys change each time.

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.
