Vehicle won't turn off

On driver side of steering column should be a part that looks like a hollowed out key (you're going to need to remove covers to find it. Should be almost directly across from ignition switch. ) if broken it won't be able to shut down.

That's the part I changed and it still won't turn off

This is the ignition starter switch

This is the piece I was referring to

Ok thanks I will check that part after work

I can't find that part

This is where the ignition starter switch sits
