Alright, how about finishing the answer....I already know you have to access it through the interior panel, since there is no way to get in through the exterior part of the hatch. How do you take the interior panel off in order to gain access to the lock and once you gain access to it how do you "trip" the lock to open it?
Hello, I am another expert trying to further assist you with this problem. At this point I think you are really looking for info on how to remove the interior trim panel. Here is how this is done. The gate being stuck shut is going to make this difficult.
