How do I heat the PAL key?
1 of 7: You need to take it someplace warm, in order to heat the key.
2 of 7: There is a place that is warm nearby.
3 of 7: Take the key to the blast furnace (you'll need to go up the elevators again).
4 of 7: Go into the steam room, by heading down from the large door after getting off the elevator.
5 of 7: Run around a bit until the key turns red, then go back to the elevators and go back down.
6 of 7: Hurry through the warehouse so the key doesn't turn blue, and head back to the control room.
7 of 7: Insert the warm PAL key into the final terminal.
