Thanks you all. We lucked out, turns out GM planned for just such a problem, they left a hole in the latch that lines right up with the striker. We run an allen wrench through the opening in the latch from inside the door and loosened the striker and got it open. Turns out it does hang up if you close it a fraction too far, I have the latch here at work and am gonna clean it up and try lubricating it and see what happens tonight.
