I am running 2 Kappa 40 liter hard side bags on my 02 DL1000 and am considering replacing them with 2 new Givi Trekker 46 liter cases. I also have a Kappa K48 topcase which I'm planning on keeping. Am planning on replacing all 3 cases with new lock cylinders. Are the key cylinders interchangeable between the 2 brands & case types? I want to use 1 new key for all 3 cases. Possible? I already know the mounts are compatible.
