Hi
Im a new user on this site from Estonia, so please take it easy on me

Let's move to the problem. I have a Omega V6 1994 and i took off the battery and but it back, after that the display shows a big F__L and it wont start at all.
Before the battery change everything was very good. The original keys don't work, it has a new alarm but factory immo at least i think so

Can anybody help me how to turn of immo? Sorry for the confusing text
