New to the riding experience, fresh out of the course last week! Yup, bought an Aero shortly thereafter! I love this thing....sad to see it put away for the winter in a couple of weeks....Anyway, bought used, and have need for a new gas cap (swinging door not there to cover keyhole). I can buy new, but that will mean 2 keys. Can these lock cylinders be swapped out for transfer to the new gas cap, or do i need to buy the entire 4 lock set and replace all to maintain one key? Thanks for any help anyone can provide!!!
