350z Won't start, locks & auto start won't work
 

I normally don't use my auto start (previous owner installed it), but lately I have out of laziness. I had this problem before when I used it often so I'm thinking it could be something wrong with the auto start. The problem now is the locks don't work on my key and even when I manually try to start my car with the physical key it does not work at all. Any way to better diagnose this problem? I have work in the AM and need to figure this out ASAP. Thanks!

take it to the dealer

Yank all that aftermarket autostart crap out of your car (every single wire and connection) and see if that fixes the problem.

That feature is so pointless, it makes me want to punch the person who came up with the idea.
