Integra 95 LS won't start
 

hi all

couple days ago I left my car keys in ignition (maybe in start position, not sure) and locked it, after I unlocked the car, approximately 8 hours later when I unlocked it didn't start anymore, its not even trying to start, I thought its batteries, then I bought jumper cables and hooked it with other car, it still doesn't start... what should I do?

thanks in advanced
