If you accidentally press the lock key of your air conditioner, you can unlock it by following these steps:
1.Check the buttons on your air conditioner's remote control: First, double-check if there are buttons on the remote control with a lock shape. It is usually labeled as:"lock"、"child lock"or similar text. If so, press the button and keep pressing for a few seconds.
2.Check your aircon's manual: If you can't find the lock button on your remote control, you can check your aircon's manual. In the manual, you can find instructions on the lock function and how to unlock it.
3.Power Reset: If neither the keys nor the manual unlock the air conditioner, you can try to do a power reset on the air conditioner. First, turn off the power switch or unplug the power switch of the air conditioner and wait a few minutes before reconnecting the power or turning the power switch on.
4.Contact after-sales service: If the above methods still fail to unlock the air conditioner, it is recommended that you contact the after-sales service center of the air conditioner brand to consult them about the specific unlocking method or get further help and guidance.
Please note that different aircon brands and models may have different unlocking methods, so it is best to refer to your aircon instruction manual or consult the brand's after-sales service center for accurate unlocking guidance.
