Just a quick thought - can you put the keys on a floppy and mount
it/access it appropriately?

Advantage: security, as you always have your key with you
Disadvantage: security, as you may lose/forget it when going back and
forth between the two locations. And losing it means that you are
completely at the mercy of the person who finds it.
