There is a relatively easy way to convert your lock cylinders to the ignition key. It is less secure, but allows the user to use the keys that came with the locks, or the ignition key.
With the lock cylinder removed, remove the lock key (careful not to lose any of the wafers), and insert the ignition key. You will see that the wafers do not all line up flush. Simply take the cylinder to a grinder or file away the protruding wafers (carefully!) until they are flush with the cylinder barrel. File or trim away any swarf so that everything operates smoothly, and install the cylinders. The bags can now be opened with the original lock keys or the ignition key.
It should be apparent that this is not the elegant or factory recommended option, but has served me well with many BMW cases. YMMV![]()
You could certainly go down that route, but since the wafers only come in 3 different versions, and they're numbered, it's not a big job to swap the ones you have around until most of them sit flush. After changing the locks twice to match two different bikes on one topcase, I've still got a barrel with only one wafer missing. And I've stayed away from the grinder.
