Need a slim jim...

Hi, my girlfriend locked her keys in her 96 lumina. I tried getting it unlocked with a coat hanger, can see the locking mechanism by prying back from the window. Coat hanger isnt able to pull it. I need a slim jim. Can they be bought at a part store such as advance autoparts? Also, which way should i be doing this. SHould I pull up on it or push down. I can't really push down with a coat hanger, but pulling up didn't seem to do anything. Basically, which way do you turn the key to unlock it: left or right? She uses her remote so she doesn't remember.
