Broken Key Loop


One of my MK5 keysfobs broke off the little key ring that is at the top, which is where it attaches the keyfob. It's believed to be made of very soft metal or plastic. I've made a hole in it, and then wet-sanded it to strengthen it, but I suspect the problem isn't resolved by that.

I've also tried wrapping the broken portion of the ring in clear tape, but it does not seem to do any good. It's really too bad because I use the rings to keep my keys on the little mini-split ring which holds the larger split rings for the other keyfobs.

If the case of the key fob is damaged, you can usually open it and replace the battery, if it isn't dead. Online kits are available, but they only provide a temporary solution. It may be quicker to get it fixed by a professional. You can also find the new case at a locksmith or home improvement store. They're not likely to be as expensive as the new key fob.
