Search is your friend, but you have to do a google version to search this site on three letter words. The ILCO YM63 is well known.
LINK for online if someone doesn't have a local source.
Seems like someone discovered that the ILCO X254 key would work for short keys to open the hard bags or gas tank, but not the ignition.
LINK I ended up cutting down a YM63 and pressing it into a plastic knob for a gas cap key that stays in the cap, so haven't tried the X254 blank.
