Fob not working remotely after FEM ISN change
So guys part 3 of my trouble with this car,

After setting donor ecu isn to FEM,  had to do fresh immo, so add new keys, I added new key, sucesful, car start but only when holding key close to the steering column, no lock/unlock. New battery in fob etc.

I tried 2 different new keys, also original key virgin and reapply, nothing.

Decided to try different FEM, even changed frequency from 434 to 868 and added another key, still same. 

ANy ideas?

I agree, in my experience original keys virgined don't work remotely. Use new blank keys from trusted source.
