Broken Key Loop

One of my MK5 keyfobs has broken off the little key loop on top where it attaches to the keyfob. It's made of soft metal or plastic. I've punched a hole and then wet-sanded the area to strengthen it but I'm guessing the problem isn't helped by that.

I've also wrapped the broken portion of the ring in clear tape, but it doesn't seem to do much good. It's a shame, since I use the little rings to hold my keys on the mini-split ring that holds the larger split rings for the other keyfobs.

If the key fob case itself is broken it is usually possible to remove the case and replace the battery (assuming the battery isn't already dead).
