Ignition problem
 

I went to start my car today n it didn't start..all the power came on but nothing happened. I pulled the key out n back in and nothing happened. I actually had to keep the key all the way to the right n it started. I took it in to a mechanic and they couldn't duplicate it. They check everything from the starter to the switch n couldn't find anything wrong. Any ideas that these guys couldn't think of?

Oh by the way if you didn't know I have an 02 ss. Sorry if I didn't say so earlier
