Scourge Wastes Chests for the Keys

etched wrought iron key unlocks "a wrought iron treasure chest", which rewards advanced solo quality gear.
polished pyrite key unlocks "a pyrite treasure chest", which rewards heroic quality gear.
etched blood iron key unlocks "a blood iron treasure chest", which rewards raid quality gear.
- Ancient iron scraps can only be sold for status.

These chests spawn randomly in various locations throughout Zek, the Scourge Wastes (Solo) and Zek, the Scourge Wastes (Heroic).

The Tracking ability can be used to locate these chests.
If your class/race can't track, consider hiring a mercenary with tracking and have him track for you.
Chests show up in track as even (white) at level 100. You can also just filter for "chest".
