Heart and Key Earrings

Got the keys from an lock dairy that I couldn't open the keys to it won't open it, so I took the dairy appart (the lock strap of it anyway) and left the lock on the cover, because I couldn't get it off without tearing up the dairy completely. At first I was going to make the keys into just key earrings, but while I was getting the parts to make the earrings, I found some left over charms in a container and then this thought came in mind.
