doors are stuck and need to be opened!!!

[SHO--ripper]

My rear doors are stuck shut and I'm going back to college in 3 days. I need to have them open so I can pack my car. At first I thought it was the locks that were stuck shut but I put a new switch in and they still didn't open. I removed the door panel and realized that the latch that holds the door closed is rusted shut. I tried kicking the doors out with the handle pulled up but still couldn't get them open. I also tried spraying WD-40 through the crack in the door in order to get it into the frozen latch but it doesn't seem to have worked. I'm running out of options and don't want to pay a shop for the work. If anyone has had this problem and found a way to fix it please let me know soon. I have both door panels off so if there is a way to get to it from inside the door panel please let me know. Thanks.
