Clarify what is included

Questions from the homeowner’s side.
What does vintage mortise lock service involve?
A mortise-lock assessment checks the case, springs, levers and key operation. Ask whether worn components can be serviced and matched, or whether a compatible replacement case is needed. Confirm how existing door joinery will be preserved.
What should the proposal say about parts, materials and equipment?
Discuss case springs and followers, lever packs, skeleton and bit key blanks, period-pattern replacement case if needed. Ask the provider to distinguish existing parts to inspect, proposed replacements, and tools, materials or reports included in the service. Request a reason for any replacement and confirm compatibility with your equipment. A list of possible items does not mean that every item must be supplied or replaced.
Do I need rekeying or a replacement lock?
Rekeying changes which key operates a compatible lock while keeping the main hardware. Replacement changes the hardware itself. Ask whether the current lock is in suitable condition, whether keys are missing and whether you want a different function or finish. Those details are more useful than choosing a service from the symptom alone.
What information should I have ready for a locksmith?
Describe the door or vehicle, the lock type if known, and whether the key is lost, broken or turning without opening. Have the information needed to establish authorization to access the property ready. For vehicle work, the make, model and year help identify compatibility; confirm the exact requirements with the provider.
Can a smart lock fit my existing door?
Compatibility depends on the door preparation, thickness, existing hardware and the product’s requirements. Ask whether the proposed lock fits the current holes, how it is powered and what access remains available if the battery or connection fails. A photograph can help a preliminary conversation, but installation fit still needs confirmation.
What belongs in a locksmith quote?
Ask what the visit includes, which parts are included, and whether opening, rekeying or replacement are separate items. The provider should explain any work that would change the original scope before proceeding. Keep the invoice and the details of the fitted hardware for future key or maintenance questions.
Why might a door still be difficult to lock after changing the cylinder?
The cylinder is only one part of the door assembly. Door alignment, the latch, strike plate and closer can affect operation. Explain whether the problem changes when the door is open or closed, without forcing the hardware, so the assessment can consider the door as well as the key mechanism.
