Lost Keys — Same-Visit Rekey

The renovation wrapped up in the spring. The crew was good, the kitchen looks right, and the key you handed the foreman on day one was never handed back.

In plain words

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.

Sound familiar?

A roommate moved out on bad terms and says the key was left on the counter. It was not. You have already changed the Wi-Fi password, but the front door still opens for a key that could be anywhere.

How the visit goes

How the visit goes

  1. 1

    Can all these doors share one key?

    With the cylinders read, the locksmith can say whether the whole property can live on one key. Cylinders from the same keyway family accept the same blank, so they can be pinned to the same combination. Where the front door is one family and the garage entry another, the choice is to keep two keys or swap one cylinder for a compatible one during the visit. Five-pin and six-pin cylinders, and homeowner-rekeyable types, each have their own limits on what they can be matched to. A minute of comparing keyways before the work begins is what makes a single ring possible afterwards rather than a near miss.

  2. 2

    Removing the cylinder without disturbing the door

    Each cylinder comes off in the way its lock allows, and the door itself is never cut or drilled. A knob or lever lock releases its cylinder once the knob is slipped off its spindle and a retaining clip or cap is eased back. A deadbolt cylinder comes out when the interior thumb-turn assembly is unscrewed and the housing lifts away. A mortise cylinder in an older door backs out after its small set screw is loosened, and a rim cylinder on a night latch unscrews from its back plate. Each piece is set aside with its own screws so the door goes back together exactly as it was.

  3. 3

    One key on the ring

    If the house was keyed alike during the visit, the ring that goes back in your pocket is lighter. One key opens the front door, the back door, the garage entry and the gate. Each family member carries one thing instead of a jangle, and the question of which key goes to the dog walker has one answer. New doors added later, a shed or a workshop, can be pinned to the same code when they are installed. Guests and sitters find the arrangement easier too, and a single key is a good deal harder to lose than a bunch.

What affects the quote

  1. 1

    Travel to the property

    Every call-out includes the drive. A house across town and a rural property at the end of a concession road involve different time on the road, and the quote reflects the trip.

  2. 2

    Upgrades chosen during the visit

    Some people take the moment to move to a heavier deadbolt, a restricted keyway, a reinforced strike or a lockbox for the spare. None of it is required; each option is a separate line.

  3. 3

    Paperwork for a landlord or building

    Where a landlord, condominium or lease requires a written record of the lock change and key count, preparing that note and any key register update is a small named item.

Lost Keys — Same-Visit Rekey: questions

Advice · (226) 785-2980

Can I just have another key cut instead?

You can, and it solves being without a key. It leaves the lost one working, though, which is the half of the problem that keeps people awake. Rekeying takes about as much effort as a trip to a hardware store counter and ends with a new key in your hand and the old one retired. If the key was mislaid somewhere it will never be found and named nothing, a plain copy is a fair choice.

Does stamping keys 'do not duplicate' stop copies?

It asks; it does not compel. The stamp is a request that a key-cutting counter may or may not honour, and manufacturers say as much. Real control comes from a restricted keyway, whose blanks are issued only through authorised channels against a key card, or simply from knowing how many keys exist and who holds them. A rekey resets that count to a number you chose.

Should I rekey when I move into a new home?

Lock manufacturers list moving as one of the main reasons to rekey, and it is easy to see why: previous owners, their relatives, a cleaner, a dog walker and a contractor may all hold copies you know nothing about. Rekeying every exterior cylinder in one visit resets the count to the keys in your hand, and it is a convenient moment to put every door on a single key as well.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
