Broken Key Loop
One of my MK5 keysfobs fell off the tiny key ring that is at the top, which is where it attaches the keyfob. It's believed to be made of very soft plastic or metal. I've punched a hole and then wet-sanded it to strengthen it but I'm guessing the problem isn't helped by that.
I've also tried wrapping the broken part of the ring with clear tape, but that didn't seem as good. It's a shame because I use the little split rings to keep my keys in the right place.
If the case of the key fob is damaged, you could often remove it and replace the battery if the battery is not already dead.

Alternatively, you might find the replacement case at an home improvement store or locksmith. They are not likely to cost as much as an entirely new key fob.
