[bluesky]

Hello.everybody


I added a spare key for bmw 320i 2007 6 months ago using a Chinese  market key.

I've heard from a customer that the battery of the car key only goes for about 3 days these days, is there a high possibility that the car key is defective?

For the original key, I made a spare key because the remote control button was broken, and I can't check how long the battery lasts.


Thank you so much.
