Remote controls have very short range or only work when very close to the opener.

Safety first: Use a stable ladder when accessing the opener head and antenna.

• Replace remote batteries: Install fresh, correct-type batteries in all Mighty Mule remotes.
• Inspect antenna: Ensure the opener’s antenna wire is fully extended downward and not cut or coiled.
• Reduce interference: Replace nearby LED bulbs with garage-door-opener-compatible bulbs and move Wi‑Fi routers or other RF devices away from the opener if possible.
• Test from vehicle: Try operating from different angles and distances to rule out vehicle window tint or metal obstructions.
• External antenna: If range is still poor, consider adding a Mighty Mule-compatible external antenna kit if supported by your model.
