Compare normal observations
Note whether the issue affects one remote or several, and whether the wall control has shown the same problem. Include where the vehicle was during ordinary use. These details can help frame the assessment without turning repeated button presses into an improvised diagnostic procedure.
Identify the accessory and operator
Keep both model details where accessible. A remote that looks similar to a replacement online may use a different supported system. Ask compatibility questions before purchasing a control, especially if the household also relies on a keypad or built-in vehicle button.
Keep broader symptoms in the request
If the door also hesitates, reverses or makes a new noise, report that alongside the remote concern. Do not let an intermittent control complaint obscure an operating issue. The quote should explain which part of the system the proposed work addresses.
Your questions
Should every remote be replaced together?
Not automatically. Establish which controls are affected and what the existing equipment supports before deciding on the scope.
Can distance alone identify the problem?
No. The circumstances are useful observations, but they do not establish a particular failed component without assessment.
