I just deployed/used the panel myself. It seems to work fine, with a small problem.Edited By: Mozinwrath Blackfrost on Year 12 Day 121 12:53
In the Equipment screen, hit "Deploy" in the room you want it in. Then the option to "Use Panel" will appear. Clicking on it brings up the room map for the entity, with the options to "Lock All Doors" and "Unlock All Doors".
I dropped my keycard to make sure it was functioning, and it seems to work fine. Except the spaces in between the rooms do not update (Mine apperars that they are locked, with the segmented dividers between the rooms still).
Edit: Having locked the doors again, I can still move through the ship with the doors locked (and still without the keycard). So something isn't right.
