Sky Keep is the last dungeon in Skyward Sword and it's an unusual one at that. You're able to manipulate the position of each room of the dungeon, there's no boss, & ultimately the point is to find all 3 Triforce pieces.
Entrance Room (0:00): Get the map from the chest and head over to the control panel next to the door. Move the middle-right room down and the middle room to the right so that those 2 rooms are connected to the 1 you're in. Then go through the door.
Skyview Temple Room (1:36): Go to the right and use the Beetle to knock the rope loose. Use the Whip to swing over to the rope then use the rope to reach land.
Clawshot to the 2 vine covered cylinders and then to the target in the fish's mouth. Drop down and use the Beetle to grab a bomb on the cylinder and fly it over to the Pyrups to kill them.
Use the rope to reach the swinging platforms and the Gust Bellows on the platforms to reach land. Jump onto the lever to create a shortcut between this room's entrance and exit, then head through the exit.
Lanayru Mining Facility Room (3:25): Grab the Timeshift Orb to the left and go down the stairs to the right. Kill the Sentrobe then climb up the ladder and pull down the lever raising the bars down below. Grab the orb, step on the switch, and throw the orb onto the conveyor belt.
Go back up the ladder, run to the end of the room, and step on the switch to make the orb fall down in front of you. Take the orb into the next room and place it on the moving platform and blow air at it from afar to make it move. Step on the switch on the floor and shoot the other switch until the orb reaches the end.
Take the orb into the next room and pull down the lever to create a shortcut. At this point it's a good idea to take out the 2 nearby Beamos. With that done, take the orb, step on the switch, and drop the orb on the conveyor belt. As the orb moves, shoot the 5 switches as you're able to. If you miss any, use the whip on the lever in the middle of the room to make the conveyor belt change directions.
Once you hit all 5 switches, you'll be able to use this room's control panel. Move the top-middle room down 2 places and the room on the bottom-left up and over to the middle. Head back into the Skyview Room and then into the 1st new room.
Earth Temple Room (7:12): Crawl through the hole to the left. Go left and roll a bomb back into the hole to blow up the rock. Crawl through the opened path and dig down into the dirt to the right. Hit the switch then head back to the newly opened area. Defeat the Lizalfos and throw a bomb into the statue nearby. Roll a bomb down the sand slide into the 2nd statue and then slide down after it.
Climb up the vines and cut the trees down. Use the Beetle to drop the bomb into the 3rd statue and then shoot the crystal switches that the statues were hiding in the order of 2 1 3 (21 is number...3?). Dig down into the patch of dirt in the new area and hit the switch granting access to another area.
Dig down in this area and defeat the 2 Moldorms below to exit. Pull down the lever to create a shortcut then head into the next room.
Dreadfuse Room (13:51): Dreadfuse is very similar to Scervo from the Sandship. Block when he tries to zap you in order to stun him giving you a chance to hit him. When he's defeated, grab the small key in the chest.
Go through the door and use the control panel. Move the rooms around the middle room until you're connected to the green Triforce room.
Ancient Cistern Room (16:09): Head through the locked door and defeat the 2 Moblins. In the 2nd room beat the several Bokoblins and 2 Stalfos. In the 3rd room defeat the Stalmaster and several Cursed Bokoblin.
Once everybody's dead, go into the next room, thrust your sword into Farore's mark and grab the Triforce of Courage. Go back to the Dreadfuse room control panel and move the rooms so that you can enter the red Triforce room.
Fire Sanctuary Room (22:20): Navigate this room by shooting down Water Fruit to create platforms and shooting switches to change the lava flow until you reach Din's mark. Thrust your sword into it and grab the Triforce of Power.
Climb the vines to go back to Dreadfuse's control panel. Move the rooms so that the blue Triforce room is above you and the 2 rooms before it create a path from you to the Triforce room.
Sandship Room (29:27): Grab the Timeshift Orb and place it on the opposite side of the room so that you can shoot the switch. Take the orb into the hallway, but drop it before the Quadro Baba appears. Run over to the ground switch and shoot the 2nd switch.
Take the orb near it's home and jump off the back ledge to land on top of a platform. From on top of the platform, throw the orb down toward the mark and use the Clawshots on the target. Stab Nayru's mark to get the Triforce of Wisdom.
