Keys for certain locked doors?

I tried looking this up, and only found things for “giving sims house keys.” So forgive me if there’s more than one post on this.

I’ve been wanting for some time now physical keys for certain doors. You can lock doors for certain people, but I want to have doors in houses where if you find the key, you find the secrets. Adding in like a whole “mystery mansion” kind of play. I was hoping that realm of magic would have had something like this. Anything to unlock doors, since you can’t use the temple mechanics from Jungle Adventure in your house. Something like, Red door, needs the Red Key.(blue, black, gold, white, skeleton) Separate doors for this interaction in the buy mode, and a physical item is placed in the house hold inventory for the sims to take and physically lock, and then they can either hold the key in their personal inventory (although I’m not sure how you could con it off their inventory if you’re not inside their Family household?) or have to place it on a surface or inside a chest.

I thought it would have been fun, idk if anyone would think so too? Also, I haven’t found any mods for this if anyone else has, let me know!
