Car will not start , everything checks good ,fuses, battery ,alt.,& starter.

What is your question?

The car will not spend over at all . Never ever had a problem before . I have hit the Key with the car running in the ignition switch with my knee several times could that cause a problem ? Do the key need to be reprogrammed ? Could it be the ignition switch ?Could there be some type of switch that needs to be reset ? or a electric problem? Hopefully someone has experienced this problem. I'm lost & puzzled please help.
