HI: 98 contour motor won't shut off, the key won't turn to the off position so I have to disconnect the battery. Chiltons says to depress a pin through a hole on top the cylinder, but it won't depress even w/ a hammer, so second option is to drill it out which I did but the cylinder still won't pull out. not with prying or a wrench. the key still turns so it's not crushed but it just never got the memo from Chiltons. Does anyone know what to do next? Thanks.
