i locked myself out of my car

Aside from calling a lock-opening service, you could purchase one of the tools that the locksmiths use -- a piece of thin metal with a hook on the end. Slid down between the glass and the weatherstripping on the door, you can hook the lock actuator and pop it upwards. It takes some practice and you can sometimes damage the lock actuator by unhooking it from the latch assembly. My suggestion? Call Pop-A-Lock or someone like that, pay the $50 and get on your way again.
