A free mod for Fallout 4, by lyravega and Neanka and Old Nick.
KeyNuker and KeyRing - Hidden Keys is a mod that allows you to hide keys (and passwords) in keyRing. You can find the keyRing at the bottom of the MISC tab. You can also use this with any other string replacement mods, and/or languages.
The keyNuker mod is based on the idea that if a key is used to open a lock, then the key should not appear in the inventory, but instead, be hidden under the keyring.
If you're using a keyboard, you can now use this keyNuker mod to hide the keys. KeyNuker will no longer appear in the inventory but instead will be hidden under keyring.
This mod also allows you to hide passwords in keyRing, which is useful if you don't want other players to see your passwords in the game.
The structure of this mod is very flexible, which allows you to use it with any other string replacement mods and/or languages.
