I need some help. My dad just died of pancreatic cancer last week. I've been looking through his things and I found this on his keys. Does anyone know what it is/does? He was the kind of guy who only carried useful things in his pockets, so it probably is some secret tiny thing that actually gives you an oil change and tire rotation, but it's driving me nuts that I don't know. And without any idea what to look FOR, Google hasn't been much help. Does anyone know? Any help/tips/advice appreciated.
