You need your disc cleaned - take it to a local Play N Trade store and they should be able to get it back to work correctly

SOURCE: i cant find the big key of the lakebed temple (wii)

Do you remember the room where you get to a door by Claw shoting to a vine then another then a third? Enter the room I'm discribeing at the lower level and claw shot your way across(make sure the wheels are spinning). When you go in the door, jump in the water and make your way to a crack at the bottom of the water. After you go through the crack head right and swim up to a under water bomb rock guarded by a fish that blows up. Hold Z on him and grab him with the Claw Shot. When he's in your clutches throw it at the bomb and go through the hole. Now go down and you'll notice another bomb rock. Blow it up to find ****. Kill it and go up to find a door. Go through the door and aim up with the claw shot. Lower your self through the newly open hole to find the Boss Key chest. Now go through the door in the water quickly to ovoid the fishes to end up in a tunnel. Go through killing the Bari with the claw shot to find yourslf back at the section where the second bomb rock was. Work your way back to the room with the stairs to fight the boss. As an extra go to th 2nd floor in that room and aim your claw shot at the medallians at the celing. A chest with a Heart piece awaits. Now go to the first floor and travel west(left according to the map) and make the water flow through the door with the stairs. Go through the door and go on the floating bridge. Defeat the lizard and use the claw shot to get the last heart piece in that temple.

The disc might be scrached, you can take a soft silky dry cloth and try to clean it, if it doesn't work you can try and get a new one.
