How do you remove the ignition switch on an '82 300D?

I have an '82 300D and am trying to remove the ignition lock and switch. The key will still usually turn to all positions. I read that the key has to be in position 1 then a wire is inserted and the lock is unscrewed, but I am a little confused about that part. Any help would be appreciated.

lock removal

Things I have learned about lock removal: The best wire for me has been a mebium sized paper clip with half of it straightened out, it needs to be flexible. It needs to be inserted into the notch at an upward angle and to a depth of about 1/2 inch. If you can only get 1/4 or less try a differnt angle. It is the black metal caseing around the lock that unscrews. You should be able to unscrew it fairly easily. If it won't go, reposition the paper clIP, I usually take a spare key and trim the head to fit through the black surround. It can be removed and installed without this, I just find it easier. You can use a smaller paperclip to hold the pawl down as you re-assemble. Press the pawl down and insert it through the two small holes that line up. Relax and be patient! It will work! Hope this helps.
