B1011 : BATT power supply (control) malfunction
B1012 : BATT power supply (backup) malfunction
B1013 : IGN power supply failure
B1014 : ACC power failure

I checked fuse's but all are fine...

I know you charged the battery but check it again. Either it is toast or you have a really bad cable connection at the posts.

This could possibly be an ECU problem as well, maybe try and get the ECU flashed and see what happens

Yes, lights come up normally with bo issues, battery voltage is good too.
Im happy to say that I solved the problem. Was that simple I cant belive it caused so many problems. So few monts ago I had my passenger window changed. Since then I couldnt open the passengers door with key in my pocket. I mean I could open it clicking Unlock button twice on my key fob but not by grabing the handle with key in my pocket. Someone didnt plug the switch when I had my window changed and thats why it was causing immobilizer and start up problems... I pluged it in, deleted all codes and car runs without issues now... thanks for trying to help me. Im happy to drive it again.

I was going to comment on this saying that "Passenger side external antenna output stage open" means something is wrong inside the passenger side door sensor, but looks like you figured it out!

Sorry to resurrect a dead post but did you resolve these codes?
