I do have a lite plastic key fob on my key. Made me think of the weight thing causing problems. I was up in northern Arizona a couple of years ago and stopped to gas up, my ignition key was missing. It had fallen out of the ignition with the bike running. I like to learn the hard way. I removed the ignition switch in Page,Az. Had to barrow tools to do that. Took the complete ignitions switch and had two brand new high quality premium keys made for around $80.00, which I was actually very grateful for and very happy that's all they cost. Figured it was cheaper than renting a truck and hauling my bike home. Since then I always carry an extra key, do not hang extra keys on it, and I have an extra at home also. Since then I have also move the ignition from the side mount system up to the handlebars, which I like much better. Oh and yes the new keys have warn down and yes it will come out of the ignition switch in the run position. I personally think the Victory (China made) ignition switch is a cheaply made piece. When it fails I may wire in one from a Honda or a Suzuki, or a NAPA ignition switch.
