I changed the battery on the BMW e65 key. Everything is great. Previously, he only worked near the door, now he catches it from a long distance. I recommend
10 rubles for replacing the battery is frankly expensive. Why such a price if they sell batteries for 2-3 rubles in a nearby roller? The remaining margin for the replacement?? Not bad... But you need to think about people too, not everyone has a lot of money.
