I've been looking at some pictures of other cars and I'm pretty sure I have the 126.

In my continued reading, I see that most MB dealers can have a replacement cylinder in ablut 3 days for me. That's not too bad, but the closest dealer is an hour away from me. Just a pain, but oh well.

I have read conflicting statements as to whether any trim pieces have to come off before removing the cylinder. Any clarification?

Do I understand correctly that once the new cylinder goes in, or if I use a screwdriver in the meantime, that as long as the ignition turns I do not need to worry about a lock up of the steering wheel lock causing me a problem?
