大家好我係邱Sir，如果車匙遙控器怎樣按都沒反應，則代表是時候更換電池了。拿去原廠換電池費用是300元左右，自己換就5元，只需幾分鐘，打開電池盒，換上原本電池的型號，便OK了。
If the remote of the car key stops locking or unlocking the doors, it is time to replace the battery. It costs about HK$300 to go to a car dealership to replace it, but it only takes a few minutes and costs HK$5 to replace it yourself.
