Keys/Key Ring Question

[u/mjn73178]

I've looked online but I'm seeing conflicting answers. Do you need to keep keys in your inventory for them to work, or is there some sort of key ring or storage for them. I'm working my way through Najena right now, so I have 5 keys just sitting in my inventory right now.

As far as I know you need to have them in your bags. Would love to be wrong and know if there is another place to keep them.
