So the latest Landy has a few weird and totally useless keys attached; old padlock keys, snapped ignition key, etc.

My brain won't let me throw any of them away, so they've been demoted to the spare keyring that lives in the special drawer that exists only for such things.

Two of them have peaked my interest though. The Transflo one I have googled, and the info pack states it's a fuel management datakey for the military. I'm sort of hoping I can get free diesel from somewhere with it! The simple key to the right looks familiar, but I can't ever remember the purpose for which I may have used one. Dost thou knoweth?
