I have to retake my DAT and the one part that is currently killing me is the Keyhole section! What does it mean when it says that the 3D object and the openings are drawn to the same scale? Are they proportional or is each side of the object the exact size/measurement of the opening? Thanks guys!

It means that the key hole has the same shape as one side of the object. So you have to rotate the object in your head in three different angles (top-front-side) and check if the view matches with the keyhole.
 
When they say the figure and keyholes are drawn to the same scale it means that the shape cannot be shrunken or blown up to fit the keyhole. When rotated to a specific orientation, it should slide through the keyhole perfectly. If the shape is a cube and one of the answers is a square that's smaller than all the sides of the cube, it's wrong.
 
Ok so if the shape is say a cube, then you're saying that one side of that cube drawn on the test has to be the exact size of a side of a square opening for that square opening to be correct?
