After local dealer (not the one I purchased it from) told me that accessories are not covered by warranty, I attacked the problem myself. After inspecting companion box, I found the screws hold the lock into the latch mechanism had partially backed out. Theorized that perhaps one or both came out on the problem box. The rear hinge pins are pressed in from the outboard side of box, & inboard ends of the hinge are capped. I used a small brad nail & channel lock pliers to force the brad through the cap (very easy...pretty soft plastic) & onto the hinge pin, and then pushed the hinge pins out. Only outboard end of pin is knurled, the rest is smooth, so I only had to push it about 1/2 inch. Once both pins removed I could lift the lid from the hinge end, reached to lock end, removed rubber lock cap & confirmed that one screw was loose & the other was missing. I borrowed a screw from the companion box, installed it in problem box lock, tightened both screws, and was then able to open latch with key. I found the missing screw in the problem box. I re-installed the hinge pins, & used medium locktite on both screws of both locks & tightened everything up. Now everything is OK, & only evidence is small holes in hinge cap where the brad pushed through. I will check the tightness regularly now, since its fairly easy to do. Obviously, I was also then able to remove the box from the bike. Perhaps I'll post a tutorial with pics on the whole process, in case someone else has similar problem. ::008::
