Broken Key Loop
One of my MK5 keyfobs has snapped off the tiny key loop at the top, where it connects to the keyfob. It's made of soft metal or plastic. I've made a hole in it, and then wet-sanded it to strengthen it but I'm guessing the problem isn't resolved by that.
I've also tried wrapping the broken part of the ring using clear tape, but it didn't look as good. It's a shame, since I use the little ring to hold my keys in place on the mini-split ring that holds the larger split ring for the other keyfobs.
If the case of the key fob is damaged, you could often open it up and replace the battery, if it isn't dead. There are kits online for this, but they typically only provide a temporary fix - it is more efficient to take it to a mechanic who will replace the battery and reprogram the key fob. You can also purchase an updated case at an a locksmith or home improvement stores. These cases aren't as costly as an entirely new key fob.
