I am a little bit hard on my key fob. I seem to have to replace it every couple of years. They always break in the same place. The key fob still works it just will not stay on the key chain. I did not want to spend any money on replacing the key fob, even though the prices have dramatically come down.
I was thinking about how to repair it...
JB Weld, NO!
Print a case for it like a cell phone case, NO! I do not have a 3d printer!
Then just like a light bulb bursting to life it came to me, to wire wrap it like I have seen some jewelry.
