Tremor mod ruins

[The Almighty Potato]

How do you open the Chests in the Tremor Mod Ruins ?
I cant find the keys anywhere and didnt find any mobs in there carrying those keys... :/

You must destroy the TIKI Totem boss
( http://terraria.gamepedia.com/Tiki_Totem )
After that, ruin ghosts will start to spawn in those ruins.
There is a 16% chance that they will drop the key to unlock those chests :)
Also, a ghost with lantern can be spawned, he can drop Rusty lantern, that can be used to summon the ancient dragon :)
Hope I helped.
