2003 Chevy Lumina door problems

2003 Chevy Lumina. The left door handle was broken during a theft attempt. I replaced the handle with no problem, I also cycled both the interior and exterior handles and manually tripped the latching mechanism to insure the function prior to closing the door. I closed the door and again both the interior and exterior handles worked fine to open and close the door. Then I screwed up; I cycled the locking mechanism with the door in the closed position! Now I can't get the door open at all. The exterior latch has a short travel distance and the interior one has a normal travel. (As when the door is locked) I have tried a coat hangar on the mechanism I can see thru the gap between the window weather-stripping, the same between the door and frame to no avail. My question. How can I get to the latch mechanism in the door? I need a detailed breakdown (schematic) of the interior door molding showing the 'hidden' screws and how this panel pops off. I also need to know if there is another way to get to the latch or is there a way I can trip it from between the door and frame? I also believe I know what I did wrong, the locking lever is not 'timed' with the lock tumbler therefore the travel distance is not enough to unlock the door. I'd appreciate any help. I'm using every resource I can think of for advice.
