One time I got in with a slim jim quickly fashioned from a piece of metal pallet strap. Another time I couldn't pull it off, and had to call AAA.
Slide your slim jim, or bent hanger, in between the outside of the door glass, and weather stripping, near the lock button. Gently rummage around, trying to pull the lock button from inside the door.
Good luck.
