Vintage Mortise Lock Service: questions about the price
Locksmith · Toronto, Ontario

Usually yes to the first, and to the second once the locksmith checks the locks. Interior mortise latches with privacy turn buttons are lighter versions of the entry lock and respond to the same clean and re-spring. Interior locks in a house were sometimes supplied to one bit key, and where the key sections, warding and levers actually match, the locksmith can restore that arrangement so a single key opens several bedroom and bathroom doors. It is a practical thing to have when a child locks a bathroom from inside.
Whether the door has to come off its hinges
Some mortise cases can be serviced with the door hanging in place, while a tight jamb or a stubborn case sometimes means lifting the door off its hinges onto a level bench. That step is identified once the case is open and the repair needs are clear.
Paint and seized parts
Hardware buried under decades of paint takes time to free and clean without damage. A faceplate, strike and thumb-turn that have to be stripped back add to the visit and are noted in the quote.
Making the inside key-free
Fitting a thumb-turn or interior release to a deadbolt that was keyed on both sides is its own small item, and one most owners of an entry door choose to include.
