What affects the estimate?
The kind of hardware, its condition, the number of doors and whether a working key remains can affect the work. Vehicle key systems have their own compatibility requirements. For a garage door, the reported symptom helps frame the request, but the cause may need inspection. Location and access conditions also matter when arranging a visit.
Ask what is included
Confirm the requested service, any visit or assessment charge, parts, labor and applicable taxes or other charges. For rekeying, ask which cylinders and how many working keys are included. For a car key, clarify the functions to be supplied and any cutting or programming required. Ask whether the figure is an estimate subject to inspection or an agreed price for a defined scope.
If the scope changes
A different fault or incompatible component can change the proposed work. Ask for an explanation and an updated cost before authorizing a change. Keep a note of what you agreed, including the service and any conditions discussed. Availability and timing should be confirmed in the same conversation.
