How do I?

Or, you could be creative :3

Spoiler below!

Make the meat hook static, then place your non static-physic key onto it. If your key wont fit, just make the meat hook smaller :3

An idea would also to use the wooden welders to make a row of hooks, which you can place your key on one :3

Spoiler below!

The wooden plank is a welder found in the dungeonbase folder. Right down the bottom.
The hook is meat_hook, found in the equipment folder (unsure if AAMFP asset...)
The key I used was the torture chamber key. Just adjust the hook size for the 'hook' of the key.
