This room is the best space in case of storms, so I wanted a mechanical locking mechanism in case of power outages. To get in one one needs to have a magnetic item. When placed correctly, the magnet will stick. The panel warped slightly when cut and ended up keeping the latch tight until a little pressure is applied. Release both latches and voila hidden space. Springs in the back keep the panel from falling but still allow it to open. With the panel open, we see two cables. Pull one to lock and the other to unlock. This works really well right now, and if I want to go with a classic "book" opener it should be a pretty simple mod.
