Dead Key Fob Batteries
Modern key fobs let us open trunks, doors, and tailgates with ease without the need to search for a car key. Some key fobs have a built-in key that can be used to start our cars. However, these fobs are dependent on a small battery that is the power source for their remote functions.

Broken Key Loop
One of my MK5 keyfobs has snapped off the little key loop on top, where it connects to the keyfob. It's believed to be made of very soft metal or plastic. I've done a hole in the wall and then wet-sanded the area to make it more durable. But I suspect that's not helping.
I've also tried wrapping the broken part of ring with clear tape but it didn't work as good. This is a pity, as I rely on the small split rings to keep my keys in place.
If the case of the key fob is damaged, you can often remove it and replace the battery, if it isn't already dead. Online kits are available however they're only an interim solution. It may be quicker to get it fixed by a professional. You can also locate a new case at a locksmith or home improvement stores. These cases aren't as expensive as the new key fob.
