2002 Hyundai Elantra Will Not Start

Hello everyone,
My 2002 Hyundai Elantra GLS just started to "not start." There is power to the car; all lights and radio work fine. I can hear the pump turn on when I turn the key in the ignition, however, the engine will not crank or turn-over, it is just dead. I believe it is an electrical problem, though, my father thinks it might be the key, so I am going to be trying my second set of keys when they get here. Are there any other things I should check, or any known problems like this with this car?

The car had only been off for a couple of hours after driving about 3 miles when this started.

Any help is appreciated!

P.S. I have never had trouble starting the car before this. Ha! Nevermind, turns out it was the key. Thanks anyway!Car Repair Talk's forum.
