Car want start

Is there gas in it?
Is the battery dead?
Did you lose the key?

We need details of what it is doing. "want start" leaves way too much open and nobody is going to be able to tell you what could be the cause if you won't narrow it down by symptoms.

Call tow company... have towed to a repair shop.

If you can't figure out why it doesn't start... its almost certainly beyond your ability to fix.
