When I picked up my new F800ST last week, they gave me two "real" keys and one plastic thingee about the size of a big paper clip. Salesman said something about it being "for emergencies only." I have checked it and it does indeed seem to operate the ignition, open the bags and unlock the fuel cap.
Question: why is it only for emergencies? Does it self-destruct after, say, six uses?
I actually prefer its small size cuz it fits very nicely on my dogtag chain, whereas the regular "spare" key is a tad bulky hanging around my neck.
