Lost Keys — Same-Visit Rekey in The Delta
Your purse was taken from the back of a chair at a restaurant.
In plain words
If you rent, losing a key is handled in three steps rather than one. Tell your landlord first, since a lock change on a rented unit goes smoother when both sides know about it and both end up with a working key. Then the locksmith rekeys the suite door, and any other cylinder that key fitted, with both parties knowing. Finally new keys are cut for you and for the landlord's set, so the arrangement that existed before the loss is restored on a fresh combination. Landlords generally welcome the call; their hardware stays in place and their own key set is refreshed too.
How the visit goesYou 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.

How the visit goes


Which cylinders the key actually opened
The locksmith walks the property with you and tries to think like the key. Front door deadbolt and handle, the back door, a side door, the door between the garage and the house, the shed, a gate padlock, a basement walkout, the door to a storage room or workshop. Each cylinder the missing key fitted goes on a list. Anything it fitted that is not yours to change goes on a second list: a shared lobby door, a parking gate, a community mailbox compartment, a workplace. The first list becomes the scope of the visit; the second becomes a set of calls you can make with the locksmith's help while the work goes on.
Resetting a homeowner-rekeyable cylinder without its key
Some newer residential locks carry a small slot beside the keyway that lets a homeowner change the key with a learn tool, but only while a working key is in hand. When that key is the one that was lost, the locksmith uses the manufacturer's reset tool instead: the cylinder is pulled from the lock, seated in the reset fixture, and its internal sidebar and wafers are returned to a blank state. A new key of the right blank is then inserted, the learn tool sets the cylinder to it, and the lock goes back on the door taking the new key and rejecting the old one.
The code written down for next time
The new combination is recorded as a short code, either on a card the locksmith gives you or on the key tag, and a copy stays in the locksmith's job notes if you wish. That code is what makes future copies accurate: a key cut to code has fresh, original depths, while a copy of a worn key inherits every rounded edge. It also means a lost key years from now is met with a different code, never a repeat. Keep the card with the house papers, and when a new key is needed, ask for it to be cut from the code rather than traced from a tired one.

What affects the quote
Entry as well as rekeying
If the lost key was your only key and you are locked out too, the door is opened first and that opening is quoted as its own step ahead of the rekey.
The kind of lock each cylinder lives in
Knob, lever, deadbolt, mortise and rim cylinders come out of the door differently and take different care to refit. A mortise cylinder in a century home is more involved than a builder-grade knob.
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.
What to have ready
- Would you like every exterior door to work on one key?
- Do you currently have a way inside, or are you locked out as well?
- Are the door locks all the same brand, or a mix?
Lost Keys — Same-Visit Rekey: questions
QuestionsDoes rekeying weaken the lock?
No. On a conventional pin-tumbler cylinder, the housing, springs and top pins are untouched and only the bottom pins are exchanged for the same grade of part the lock left the factory with; a homeowner-rekeyable design is reset through its own procedure instead, and a high-security cylinder may also need its sidebar or finger-pin elements reset. If the locksmith notices worn parts, replacing them is offered as a separate step, leaving the lock stronger, not weaker.
How long does a whole-house rekey take?
Plan on an hour or two for a typical house with three or four cylinders, including the walk-through, identification, pinning, cutting and testing. Each additional cylinder adds a little, as does swapping a cylinder to bring a mismatched door onto the same key, resetting a homeowner-rekeyable lock or clearing a garage opener. The locksmith gives a realistic window on the phone once the list of doors is known.
What should I do before the locksmith arrives?
Walk the property and note every door the missing key opened, including the garage, shed and gate. Gather any keys you still have, since a working key helps in reading each cylinder. Have identification and, for tenants, something showing the tenancy. Decide roughly how many keys you want and whether you would like all doors on one key. If a garage remote or building fob was lost too, mention it when you book.
