You can also detect if the engine is locked by removing one of the side covers and trying to turn the engine with a large socket or wrench.  If it's locked up, the crankshaft you're wrenching on won't budge.
 
When the key is on, the run switch is on, and you hit the start button, the solenoid should click and close the high current contacts, putting the entire battery current across the solenoid toward the starter.

+1 on Re-Run's comments.  Might be a bad ground for the starter, or the solenoid is shot.
