I just tried getting in my 2006 Prius and nothing happened. I had to resort to using the key to actually get in the car, and when I pushed the button to try and start it, nothing happened. Nothing is happening at all. No lights turn on, no sounds, nothing. I'm scared, really scared. What am I supposed to do? It won't even lock itself when I push the button, I had to do it myself.

I haven't driven it for about five days, is that the problem? Did the battery die? If that's the case, how do I make it work?
