Hello and welcome to the forum.
Some Renaults have a fuse built into the main positive feed cable from the battery,you could check to see that the cables from the battery have 12 volts running all the way down through them for a start.
The immobiliser won't cut all the electrics,so don't panic about that.
I'd rather push my Alfa than drive a BMW....
