Broken Key Loop
One of my MK5 keysfobs fell off the small key ring at the top, which is where it connects to the keyfob. It appears to be made of extremely soft plastic or metal. I've made a hole in it, and then wet-sanded the area to strengthen it, but I suspect the problem isn't helped by that.
I've also tried wrapping the broken part of the ring with clear tape, but it didn't work much better. It's a shame because I use the rings to hold my keys on the little mini-split ring that holds the larger split ring for the other keyfobs.
If the case for the key fob itself is broken It's usually possible to remove the case and replace the battery (assuming the battery isn't dead). Online kits are available however they're only an interim solution. It's better to have it repaired by a mechanic. You can also find the new case at a locksmith or home improvement store. They are not likely to be as expensive as an entirely new key fob.
