One car, three different requests
If the keys are visible inside a locked car, explain that access is the immediate issue. If every key is missing, the discussion moves toward car key replacement. If you have the key but the car will not start, describe what you observe without assuming that a new key will solve it.
Share the make, model, year and type of key when known. Mention whether a spare still starts the car and whether the vehicle is in its usual parking position. Supported work needs confirming for the particular vehicle; the broad term automotive locksmith does not establish compatibility by itself.
