1994 e320 Tried to turn the key for a week as I read the bad things that happen if you can't turn it to position '1' to use the 'u' shaped tool (thin coat hanger works best - see other posts on how to bend it) with no luck. In desperation lowered the lower dash cover (easy) and smacked the column lock a few light hammer blows, the key turned, removed the cylinder (which fell apart in my hand) and ordered a coded cylinder with my VIN from MB dealer which cost about 50. and took only 2 days, installed and all is well.
