Geez I had Krausers on my BMW R100RS mate, but I'm pretty sure I gave the new owner all the keys when I sold it. Jump on one of the BMW air head sites and pose the question there? 
Terry,
I tried posting a question like that by logging on as a guest but the website wouldn't let me and I'd really have to be a BMW owner MOA or something like that to register,a very exclusive thing..
I'll call the dealers you recommended Cal.
Prokop,these Krauser keys are unobtanium according to lots of stuff I'm reading on the web
The key I need is the one that locks the 'buckle' type lock to the bag and holds it onto the Krauser rack so it won't fly off the bike when I'm rolling,the key# is stamped into the latch mech. w/ small numbers
