Pyramid keys are devices used to control doors.
Overview[]
Key devices have symbols on each exposed side of their pyramid, and the door it's a key to would have these symbols above their frames. The pyramids would need to be turned to match the symbols to open the door.
The number of pyramids needed to control a door could vary from only needing one to using multiple. A pyramid could also be the key for more than one door.
Sometimes pyramids could turn individually, while other times it could turn other pyramids also keyed to the same door.
History[]
SG-1 encountered key devices on P3X-314. (SG1: "Unleashed Ep 1")
