Does the black collar (ring with 1 and 11 marks) come out with the tumbler?I am having a hard time to unscrew the collar. I used a brazing wire, filed both ends at 60 degrees inside, turned to position II, pushed the wire in the holes till it bottomed in and used a needle nose plier to unscrew the collar. I put the plier ends in the collar holes to turn it ccw, but it will not budge. The wire goes all the way in the tumbler holes to a stop. Am I doing it wrong?
Or you can unscrew it before pushing the wire in the holes? Any one changed the tumbler in a 1990 300E. I am having a hard time to take it out.
My key gets stuck and need to replace the tumbler.
