Wont Start

Ok Guys,
I suck at cars, they all hate me. Anyways, my wife got home not 10 minutes ago and we decided to go to the store. We got into the car and she turned the key, and nothing. All the lights came on but no rev of the engine. We have had problems with the engine having trouble starting...ie: excessive revs and then having to push on the gas over and over again since it was flooding, but not this. We changed the battery not long ago so I know it isn't that. Anyone got any suggestions?

Sincerely,
Greg

What year is the car? if it's got a passkey system you should look to see if the "security light" is coming on, if so I'll give you a writeup to fix it. other than that I'd look at replacing the starter

Oh yeah, or the park/neutral saftey switch
