Well ok then, back to the key. When I bought my extra keys for the side cases I was surprised Kawasaki decided to use mirror image blanks. So you have to be careful which blank you buy. Do you think they did that to double the possible key permutations? Do they do that with cars? I've never seen that before.
I doubt that was the reason. Perhaps someone ordered a bunch of the wrong type of key and they decided to use them rather than send them back. Who knows. It's a real PITA if you ask me and I can't imagine it adds to security in any way. If someone wants into your saddlebags, lack of a key is not going to stop them. As you know, a good stiff pull will take them right off and I'm sure a quick slam to the ground will pop them open.
