Locking down house keys

[Byokii]

I see house keys locked down in the door ways, how is this done? I thought you couldn't lock anything down in that tile?

Three tables with a book on top. Put the keyring on top of that and lock it down.

Thanks!

I tried stacking a bunch of stuff, but I didn't do that!
