Check what the quote solves.
Ask whether the work concerns a control, the opener or the door hardware. If the repair includes several components, ask how each relates to the fault. This makes options easier to compare without relying on an unrelated online price.
Keep the opening clear.
A mechanical house-key change doesn't reset garage remotes or keypad codes. If you're also reviewing access after a move, explain that as a separate need.
Panels, tracks, rollers and the counterbalance system help the door move. A crooked or damaged door should stay out of use.
The motor drives the opening cycle. A running motor with no door movement needs a different assessment from a silent opener.
Safety sensors are separate from the remote. Describe any lights or reversing behavior, and do not bypass a safety device.
