Why is it the key is activated for the music box when there are no lives left?

Everytime I get the key, it's never activated until my lives are gone. The boosters are good for 30 mins. I don't get another life until they're ezpired? How fair is this?

Shouldn't you have at least one life left @jeanp8

To activate the key you have to reach the level where the key is and the only way to do that is complete the level before the key. Therefore if you have reached the key you should still have one life.

What I think is unfair about the Music Box feature is that they give you three days to reach the box, but only two hours to reach the key.
