Here are some alternative ways to unlock your remote:
- Mode + Temp Minus: On some older or specific “Inverter” models, holding the Mode and Temp Down (-) buttons together for 5 seconds toggles the lock.
- Dedicated Lock Button: Check if your remote has a tiny recessed button labelled “Lock.” You might need a ballpoint pen or a toothpick to press it.
