For a home or an ordinary business door.
Give the street address and identify the entrance: front, side, staff door or ordinary garage-entry door. Say whether the key is missing, stuck or present but not operating normally, and whether the door can currently be used.
For rented, managed or business premises, explain who can authorize a change. If the aim is to change who has access, the rekeying information may be useful. If the hardware is behaving differently, read about lock repair.
For the car or the moving garage door.
For a car, provide the make, model, year and parking location. Mention any working spare and whether the key is inside the vehicle or missing. The automotive page helps distinguish access from a replacement key.
For a moving home garage door, describe the behavior you already observed. Keep the area clear and do not operate it repeatedly or handle its springs or cables. Use the residential repair information to identify the right request.
Agree the next step before the work.
Ask whether the particular job can be handled, what current availability looks like and what the proposed charge includes. A village, lake or shopping-center name can help orient the conversation, but it does not replace an address and the correct entrance.
For a nearby town, use its local guide and confirm the actual address. If someone is in immediate danger, contact emergency services first.
