if yuo are talking about the locking plate that the single "tit" goes into to lock the wheel when you take the key out, you need a locking plate tool or something to push that platedown with. There is a clip in the center you will see once you push the plate in, remove the clip and the plate comes off, then I think the turn signal stuff is under there, move that and yuo can get to the ign lock cyl screw
