Battery is fully charged. It's not a problem with charging the battery. Must be some sort of a module that doesn't recognize the key is being charged.

Last night I've used INPA to check Status actual key and the main key I use is Key no: 1. There's one thing I don't understand. There is a line "Key Locked" and it has a black dot. Does this have to be on or?

See print screen:

I've also checked all the fuses and they are all fine.

Black dots means it's activated.what exactly is your key not doing

I can't unlock my car with remote control. I have to use the plastic key or the metal key that is attached in the remote control.

I wrote a detailed explanation in the 1st tread.

Well your problem than is the diversity ie antenna

+1, was just about to post this also.

i believe the "key locked" just means that the key is inserted into the ignition slot and locked into place.

Fixed

There were 2 things wrong:

1) Diversity antenna
2) The cable that comes to diversity antenna.

The problem was that I've tried with a new diversity already and it didn't work because the cable was also corroded. That's why it didn't work. When I opened it all over again I've noticed that cable contacts were completely corroded. I've cleaned them up and ordered a replacement diversity and ..... Thing works.

Thank you everyone for your help!

Don't think it's a programming issue either.
Can you tell me how you got into that menu, though? Just curious.

Can't remember all the steps. If you open in INPA and then navigate a bit you're sooner or later see the Actual Key Status.

Hope this helps. If you can't find it let me know and I'll connect the cable again.
