Hey guys, my 1989 white rs legacy sedan was stolen 2 Saturdays ago, sadly i wasnt even in the state to do anything about it so my family dealt with it, car was found a day later and was scanned by forensics and is now at the insurance company.

so i got back yesterday and phoned the insurance company today, turns out my car is under discussion because they dont believe it was stolen, they think a car with an immobilizer cant be hot wired so they think it was a set up of some sort, is it possible to hotwire a car with an immobilizer? can i fight my insurance company?
