Car won't start

Try to remove the battery cable for about 20 mins and put it back on and see what happens...

or try this: Sounds like the anti-thieft system has been activated. Try this: using the key lock then unlock the drivers door from the outside, if that don't work try the same thing on the passenger door. If that didn't work then disconnect one battery cable, turn on the headlight switch wait 30 seconds, turn off headlight switch, reconnect battery cable and recheck. Hope this works for you.
