Locking a treasure chest with a keystone?

[videogamefreak999]

How do I do it? It never works for me, no matter what I do.

What do you mean? That after you've unlocked a treasure chest with a key-stone, you wish to lock it again? I'm 98% sure that it's impossible, once open, always open. I'm confidently accustomed with all the buyDebug objects and the cheat commands that go along with them and I've never seen any way to lock them, in that case you have to create a new chest. If you mean a tomb you haven't created, then I can say to you that they never resets and will stay open, although the treasure they're holding might regenerate.

I'm building a tomb and I would like to lock a treasure chest with a keystone, that's what I mean.

Have you checked out the tomb creation info in the guide here:

Carl may have already posted the info you need.

Once you do all the linking stuff that involves buydebug and other cheats you need to hide a keystone somewhere possibly, link them and the chest should only open when the keystone is put in.

Does this put a keystone panel on the chest, like some of the ones in the graveyard in France?

I think so but I have never made a tomb successfully before!
