What is the reason why the new Santana key button failed for four months?

1, the remote controller is not responding. If the indicator light of the remote control is not bright or dark when pressing the key, it may be that the battery of the remote control is insufficient; If the indicator light of the remote controller is still not lit after replacing the battery, check whether the positive and negative poles of the battery are connected reversely and whether the battery is in good contact with the mounting seat; If there is nothing wrong with the above inspection, but the indicator light of the remote control is still not on, it is necessary to check whether the button is damaged.
