Answer 1

This question would need a little more information - is nothing; 1) absolutely no response when the key is turned, 2) it turns over and won't start; 3) it makes noise but won't turn over. I'll assume it's the first and the cheapest thing is to check the battery connection - terminals and cables. If you have power in the car (lights, etc), it could still be the battery but not as likely. From there, more information is needed.
