Maybe your kids decided to play tug-o-war with your keys, or maybe your keyring got caught on something and you pulled on it without realizing it. That’s okay! If your keyring is bent, it’s easy to get it back in great shape!
When the keyring is unscrewed, you want the screw threads and the hexagon shaped screw to line up pretty evenly, like the bottom ring in the photo above. You can try to bend it back into shape with strong hands, or you can use adjustable pliers or adjustable vise grip. If you use a tool, consider putting a cloth or something soft between the grips and the keyring to avoid scratching or denting your keyring.
The alignment of the screw threads and the hexagon screw will also affect how easily your keyring opens and closes. If your keyring is opening too easily, you can slightly misalign the threads and screw to add a bit of tension.
