D6D Transmission service door jammed

I have a problem that I need you professionals to help me with. The transmission servicing door mechanism is jammed. I cannot get the latching mechanism to release the door. I removed a access panel on top of the structure above the door but I cannot get the mechanism to release. I noticed a spring and a broken piece of metal inside.
I removed the latching handle on the outside, however the latching mechanism will not release.
Should I remove the hinge pin?
Any help would be appreciated.
Thanks
Kenny

Do you have an access panel on top(6 bolts or so), next to your right arm rest. If so, you can reach through and open latch from inside.

I do, after removing that’s when I saw a broken piece with a spring on it, not sure how to make the latching mechanism release though. Any ideas?
Thanks
