Problem:
I have a Xhorse mb fbs3 keylessGo key that drains its battery. Did anyone ever managed to fix a battery drain on these keys and if so what should I be looking for?
Solution:
Due to the design flaws of a few battery shrapnels, pressing the button forcefully may cause a short circuit on the circuit board, resulting in battery leakage.
To avoid this problem, it is recommended to put insulating tape on the area shown in the figure below.
