Ok something in my electrical system is messed up the past few days the car isn't responding to the key fob consistently and the dome lights and locks don't work either. This was happening about half the time. Then yesterday I pull up to the store and my car just dies but it started right back up. Today as I'm getting ready to come to work I get in my car and nothing happens. It won't start or anything. And to top it off it won't let me have my key out of the ignition for some reason.

How and where do i start to troubleshoot this. I'm guessing it probably isn't a fuse since it started doing this at random before completely quiting.
