Don't know if the 49 state bikes also require the use of the key to remove the gas cap, but in california it does. I have been able to make the cap removable without use of the key. It really is simple; take the cap off the bike, remove the two black phillips screws. Remove the plate, two plastic pieces and springs. Replace the two screws to secure the remaining metal part with the plastic. The photo below shows what you end up with, the finished cap on the left and the left over parts on the right.
