Ah, ok. Thanks, I probably opened the chest at the time and didn't realize that was what the key was for.Nah, those are different keys. Think those are "yellow/golden" and drop in the open world and you can open a locked chest after killing the enemies of that wave. There are different chests (little boxes), that can only be opened with the keys found in the sewers (like True Sons).
