卷簾門遙控器失靈可以采取下面方法：

　　The following methods can be taken if the remote control of the rolling shutter door fails:

　　步：拆卸下遙控器的外殼，將遙控器的電池取出來，然后卸下遙控器的螺絲，將遙控器的外殼拆卸下來，留下外殼、電路板、導電橡膠3部分。

　　Step 1: Disassemble the casing of the remote control, remove the battery from the remote control, and then remove the screws from the remote control. Remove the casing of the remote control, leaving behind three parts: the casing, circuit board, and conductive rubber.

　　第二步：清理遙控器電路板。將遙控器的電路板用吹風機的冷風吹去灰塵，然后用2B橡皮擦拭一下每個電路板，提高它的導電敏感度。

　　Step 2: Clean the remote control circuit board. Blow the dust off the circuit board of the remote control with cold air from a hair dryer, and then wipe each circuit board with a 2B eraser to increase its conductivity sensitivity.

　　第三步：清理遙控器導電橡膠。將遙控器的導電橡膠用棉球蘸取酒精擦拭，擦拭掉上面的灰塵和污垢。然后用手指蘸取2B鉛筆的石墨粉，或者干脆用2B鉛筆在每個按鍵上進行涂抹，直到涂抹全部常用的按鍵。第四步：把遙控器組裝回去，安上電池，就不會失靈了。

　　Step 3: Clean the conductive rubber of the remote control. Wipe the conductive rubber of the remote control with a cotton ball dipped in alcohol to remove any dust and dirt. Then dip your fingers into the graphite powder of the 2B pencil, or simply apply it to each button with the 2B pencil until all commonly used buttons are covered. Step 4: Assemble the remote control and install the battery to prevent it from malfunctioning.
