Why would anyone do that? If someone is that worried about breaking a remote key, why not just buy a non-remote master key, problem solved. I may be out of the norm, but both of my keys that are 15 years old are intact. And when one breaks, it's like $70 bucks to have the dealer cut me a new one. All this key case business seems like overkill.
The main benefit I can see is you can just have your local hardware store cut you a new key for like $2 and not worry about losing it or anything cause you can just get a new one cut for super cheap.
