I have a Helmet Guardian as well, on my Honda. It is a neat little item and generally works, but I found that the key has become VERY grumpy about going into the lock. Both sides. Maybe it's just mine, and maybe it has to do with the placement .... low on the bike and therefore sucking up a lot of dirt. But even after I clean them off and lube them, I still have to really push the key into the lock with some force. I don't use it much anymore. I dunno ..... I'm afraid that one of these days, I won't be able to get the key in, and of course, that will occur when my helmet is locked in place. Murphy. R
