Thanks to a heads-up from Aerodrome staffer Millie Thompson, I was able to locate and stomp on a bug that affected both the Raptor and Kestrel SkyBikes. If you use the blue options menus to set the lock, the lock fails to work. The chat command works correctly (e.g., “lock owner”).
If you already own the Raptor or Kestrel and would like the update to Raptor 1.2 or Kestrel 1.2, please contact Terra Quan in Second Life. Proof of purchase will be required, of course.
