Hi, I think it would be handy to include simple locks and keys for doors. The mods I've seen are either not very aesthetic or they're out of date / incompatible.

I'm currently working on a massive Silent Hill style map and I'm having the player find keys to unlock new areas. I can do it with command blocks but it's really complicated and I just thought you guys might like the idea too :)

Here's the old version of the map, which got deleted: https://imgur.com/a/lQCVwvd

BTW, I'm on 1.21. If I port the jar from 1.20.4 will it still work? Thank you
