Razor House Key
It is found in a side chamber of the court with the statues of the Lords of Xibalba who guard the entrance to the underworld. To obtain this key Lara has to pass a set of razor sharp blades. She has to run past spears and then duck the blades to conquer the room. The key has to be inserted into one of the four slots on the table in the court of the Lords of Xibalba. This key has been decorated with yellow colour.
