Wow. Good to know in case I ever have similar issues.nope just the key set me back that much.
did the diagnosis and look over the electrical side over at my work
(i work at subaru but i own a honda P)
we went over pretty much every possible causes and in my case we got it down to either getting a new key or rip out the factory immob but that would be a massive headache to do...
Glad it fixed yours! Would sucked if that didn't do it!
