My keychain/car remote broke. The small end that had a hole that allowed the metal ring to loop through it broke so I couldn't hook the key ring to the remote anymore.
They are EXPENSIVE to replace and I wanted the convenience of the remote and the keys hooked together. I thought about the shape and rummaged through my 'junk drawer' for an old plastic coin purse that my kids used to use. If you squeeze the ends, it opens to put coins OR to put my remote in there! I am sure they are in dollar stores everywhere.
It fit great over the entire remote and I could hook my keys to it again. Just a little thing to make my life easier and I've used it happily every since!
