If you have the glovebox removed as in tightening the hinges on the glovebox door and are putting it back together, tape the latch hook that is inside the glovebox in the open position with duck tape. This will prevent the push lever from the ignition switch from slipping behind it toward the rear of the scooter. It if gets behind it it won't work. When I finally figured out why the ignition switch would not activate the latch it was about the seventh time I had put everything together and taken it apart again!! After you have verified that it is working properly you can remove the duct tape and tighten all the screws and you are finished.
p.s. If you ever see how the hinge works you will be amazed that the door opens and closes at all!
