This is just a cute and useful way to find the right key in the dark. It is a cover/handle that makes it easy and quick to find the right key and have it turned the right way to insert it in the lock. The pin I made for it didn't hold up well so I substituted a squirt of hot glue into the pinhole and it has held up quite well. This is for the hex head key only at this time. I will see about adding updates for other shapes of keys.
