Hello, I have an issue with my 535 (https://eng.auto24.ee/soidukid/3912214)
​
so , the issue is that I can't lock doors when I'm far away , like I have to be really close to antenna (10-15 cm) . Can't be issue with battery of fob as car should make some sound when battery is low or show it on LCD screen right ? Also issue is with locking And unlocking with fob only , radio is fine. Can lock and unlock with key just fine.

Need to know the year. The 10+ years I've owned an E60 I've never seen a message for the fob battery. Your issue could be the fob or diversity antenna. My issue has only been the fob. Just had 2 new keys made a few months ago and everything is back to normal. I can't help because I don't what year or fob you have. Is it a key fob or a fob that slides into a slot to start the car. The more info the better

this is the key , if it's issue with antenna , then radio would not work fine either ? Not really sure as I'm completely new to this car world. Someone said it could be antenna amplifier but Im not sure if it's good idea running to change it as new one costs like 400 euros , used 200 euros.

Those are original keys. Your battery charge is at minimum. You need new keys and no you would not get a battery message for your car. That is implemented with fobs not key fobs.
