Thanks for sharing the images.
For the hatch item, under the settings dropdown of the rigid body, there is an ‘animated’ check box.
You can set keys on this setting.
I can’t see why there would be an issue any where else.
Just check the face orientation, this can have unwanted effects on rigid bodies if not correct.
Can you share a closer image of just the lower chamber, not a x-ray, a local view of this object will be ok.
