Lost Keys — Same-Visit Rekey: comparing quotes
No.

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.
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.
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.
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.
