Home Lockout Service: reading the quote

Yes, and these are usually gentle jobs. Privacy locks on bathroom and bedroom doors are built with a small emergency release on the outside, and when that has been painted over or stripped a locksmith can still operate the latch from outside with the right tool. Older interior doors with a keyed mortise lock or a bit key are opened by picking or by cutting a key to the lock. The door and trim stay as they were.

Keying other doors to match

Bringing the back door, side door and garage onto the new key after a rekey is extra work per cylinder, and simplest to arrange during the same call-out.

Interior door or exterior door

A bathroom privacy lock or a bedroom door is generally a lighter job than an exterior deadbolt, and an old keyed interior mortise lock sits somewhere between. The quote follows the hardware, not the room.

Weather on the day

A cylinder frozen solid or a door iced to its frame takes patient thawing before any opening can begin, so a winter call in a cold snap is quoted with that extra time in mind.
