Home Lockout Service: reading the quote

Three habits cover most households. Give a spare key to someone you trust who lives nearby. Fix a small combination lockbox somewhere discreet on the property for the one day a year everyone is out at once. And if you have a keypad lock, add a code for a family member and keep the mechanical override key on your keyring rather than in a drawer inside. The locksmith can set up any of these before leaving.

Type and grade of the lock

A builder-grade knob latch, a residential deadbolt, a mortise case in an older home and a high-security cylinder each take different tools and different amounts of time to open, and that difference shows in the quote.

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.

Door and frame adjustment

When the lockout was really a swollen or sagging door, fixing the cause means work on hinges, strike plate or weatherstrip. That adjustment is quoted as its own item alongside the opening.
