I tried the DIY and think I made things worse. Took the pin out and pushed the end in, wheel doesn't lock but key still won't turn. Tired of messing with it so I just want 2 buy a new one. Tried looking up that part on several MB dealerships in Houston but no luck... Gonna call Tomorrow 2 c whats up. Just wanted to find the part on line before I called. Good write up by the way rekcah, helped a bunch but I still got stuck
