I think that their is a bolt and nut thru a ring(terminology???) that surrounds the lock mechanism...I think you need to loosen it and the whole assembly when you depress the pin will slide out....I have seen this device on some of the Mercedes cars(126's) goodluck Jim

I've got the bolt out that snugs it in, the release pin seems to be stuck and good. I'm hoping a break will give me a new outlook on this, very frustrating as I tried graphite, vibration, new key, etc. I had one episode 2 days ago when it seemed I had to move the steering wheel a little more than usual to get the lock to release. I never let the steering wheel "rest" against the lock while starting, I always move it off first.

Do you have the key in the on position(all the way to the right)??? Jim

Key will not move out of the "0" position. Tomorrow I start with fresh resolve, a good nights sleep, and knowledge of the "list". How can I fail?

I had the same problem on my 560 sel, But I lost the key !!!
The only way I managed to get it off was to hacksaw through the tube section with the steering lock pin inside.
I undid the two 13mm bolts behind the clocks to drop down the steering collom, Then I sawed straight through the tube about 1-2 inches away from where it goes into the steering collom (Its not hardened so does'nt take long)
When u have cut through u will see the steering lock pin inside the outer tube.
Then u wobble the steering wheel left/right and flick out the remaining piece of steering lock pin with a small screwdriver.
A 3-4 inch pin will come out, But u have to wobble the steering wheel to release it to pull it out.
Then u can undo the little hex bolt and push the little locking pin underneath to get the remaining casing out!

Thanks, Muttley that's what I was wondering. I should receive the new lock assembly from fastlane in the next couple of days and I can judge how far away from the lock assembly to hacksaw. If anyone has ever had their ignition give them the slightest trouble, I would recommend changing it NOW.

You will probably need a tumbler and cover (black ring) also.
