Different openings can have different equipment.
If the property has more than one garage opening, identify the one involved. Door size, opener model and existing hardware matter. Do not assume that every opening uses the same parts.
Think about everyday use.
A remote, wall button and keypad may all operate the same door. Explain which ones respond and which don't. Mechanical locks on the door into the house are separate from the opener's controls.
Finish with normal operation.
After the repair, ask for a demonstration of the work and any controls included. It should be clear what was changed and which concerns, if any, still need attention.
A lock or key instead?
