I did a search and found a lot of info but the threads are old and one of the main sources of old Krauser keys seems to have gone out of business 3 weeks ago. Such luck!! I need at least one S150 key for my bag locks, not sure yet which key for bike-to-case locks. I'll post that number when I find it. Anyone have one laying around they don't need? Source of one? I did see that Krauser in Germany will sell me one for $32. but it's quite a wait so I'm trying you guys first. TIA.
