The Guards Keys
From WikiRaider
The Guards Keys are a key item found in the level Menkaure's Pyramid in The Last Revelation. They're got from an injured soldier at a house where he's under attack by a Giant Scorpion. If Lara manages to kill the scorpion before the soldier dies, she also gets the Armoury Key.
The Guards Keys are used to unlock a door at the end of the level after climbing along the pyramid.
