Broken Key Loop
One of my MK5 keysfobs fell off the tiny key ring on the top, which is where it joins the keyfob. It appears to be made of extremely soft plastic or metal. I've done a hole in the wall and then wet-sanded it to make it more durable. But I suspect that's not helping.
I've also tried wrapping the broken portion of the ring with clear tape, but that does not seem to do any good. It's really too bad because I use the rings to keep my keys in place on the tiny mini-splitring that holds the larger split rings for the other keyfobs.
If the case for the key fob is damaged it is usually possible to remove the case and replace the battery (assuming the battery isn't already dead). There are kits online for this, but they usually only offer temporary fixes - it might be better to take it to a technician who can swap out the battery and reprogram the key fob. You may also find an alternative case at a home improvement store or locksmith. They're not as expensive as the new key fob.
