Make a Bike Chain Key Ring

Finally, put the bike chain on your key ring. You do this by threading the key ring through the holes on one of the end links, if you want it to dangle down. For a bike chain loop as shown in the picture, fit open sides of the end chain links together, then thread the key ring through both at the same time. If you have several key rings, you can attach your keys to your bike chain at different places for a cool look.
