Lost Keys — Same-Visit Rekey
You were shovelling the driveway after dark and the ring must have slid out of your coat pocket somewhere under a metre of snow.
In plain words
Rekeying and replacing a lock arrive at the same place by different roads. Replacement puts new hardware on the door: a new deadbolt or handle, and a finish that may not match its neighbours. Rekeying leaves all of that alone and changes what is inside the cylinder, commonly the pin stack on a conventional lock or a reset on a homeowner-rekeyable one, so a different key runs it. For hardware in good condition, that is the sensible choice: the door looks and feels as it did while the old key is retired. A worn cylinder can be replaced and keyed to match the rest in the same visit.
How the visit goesA 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


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.
Testing every key in every lock before leaving
The last part of the work is deliberate repetition. Each new key is tried in each cylinder it should open, with the door open and again with it closed and bolted, so a pin that feels fine on the bench is proven on the door. The old key is tried too and shown turning nothing. Cylinders that were dry or gritty get the lubricant their maker specifies, a puff of graphite, PTFE or a specified liquid product, and a few cycles to spread it. Screws are checked snug, covers seated, and the pile of old keys and any swapped cylinders is handed to you or taken away as you prefer. Only then is the key count confirmed and written down.
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
Master-keyed building cylinders
A condominium or apartment suite cylinder on a building master system is pinned so the master still works, which takes coordination with management and a little more time than a stand-alone house door.
Whether the doors can share one key as they are
Cylinders from the same keyway family are pinned alike with no extra parts. A door from a different family needs a compatible cylinder swapped in if you want a single key, and that part is quoted separately.
Condition of the cylinders
A clean, healthy cylinder is repinned as is. One clogged with salt and grit is cleaned first, and a worn or damaged one is replaced rather than repinned, each priced as its own item.
What to have ready
- Is any lock a keypad, smart lock or homeowner-rekeyable type?
- Would you like every exterior door to work on one key?
- Is the property a condo or apartment with shared entrance doors?
Lost Keys — Same-Visit Rekey: questions
QuestionsDoes 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.
A garage door remote was on the ring. What happens with that?
The opener on the garage ceiling holds a memory of every remote paired to it, and it can be erased in one step so the lost remote is forgotten. The remotes still in the household are paired again afterwards, and a keypad on the outside of the garage gets a new code if you have one. The locksmith can do this during the visit, and it takes only a few minutes at the opener.
My lock is the homeowner-rekeyable type but the working key is lost. Can it still be reset?
Yes. Those cylinders let an owner change the key with a small learn tool, but only while a working key is in hand. Without one, a design such as Kwikset SmartKey is removed and placed in its own reset fixture, returning it to a blank state; other cylinder types are rekeyed by their own method instead. A new key is then set and the lock goes back on. It is a few extra minutes rather than a replacement.
