I have a theory about why the monks made Dawn the key instead of some random object.
It's her blood that is the key, and blood is constantly moving within the body, so maybe Glory couldn't see it because of the constant movement, despite it only going around the body. If the key was still in an object she may have been able to see it.
That means they could have put it in an animal, but with Buffy at college she perhaps wouldn't have been as good a caretaker as a sister.
