Out of nowhere , car won't start

[Kandry]

Hi guys 

I'm new to this forum and I thought I'd try solving this issue by asking others who might have some experience before I go to service again.

I have BMW e92, 320d , 2007 
So basically I can't remote unlock my car, when I unlock it manually no lights turn on , no lights on dashboard , no reaction whatsoever , usually when I insert the key in the ignition I would get something but it won't even lock the key in.
First I thought it was the battery in the FOB key, but today I've confirmed the battery is fine. So next thing I thought it could be was car battery , but I had it changed in service not even a year ago . 
Car was working fine couple days ago , it happened out of nowhere. 

Any ideas before I go to service ? Thank you.

Welcome to the Forum

Under the bonnet check with a multi meter for power at the charging points then check all fuses. In the boot check battery connections and battery out put, the fact that it is only a year doesn't mean it cant die.
