Stop what you’re doing immediately, and search the forum for “ignition tumbler” or “lock cylinder”. You are living on borrowed time! The problem will get progressively worse until eventually your key will not work at all (and it will undoubtedly happen at the most inopportune time). This is a common problem that can be corrected in about 15 minutes provided you can get the ignition tumbler to the #1 position. However, once your current key stops working – and you can no longer get the tumbler to the #1 position – you are looking at a VERY difficult and expensive procedure.
You can order a new tumbler that will match your current locks from your MB dealer.
But I can’t emphasize strongly enough that you need to do this immediately. Because the next time your key works, could be the last time it works… then you’re screwed!
Get the info on removing the tumbler by doing the search. Then the next time you start your car, DON’T SHUT IT OFF! Remove the tumbler. You can still operate the ignition switch by inserting the key where the tumbler was. (At least I could with mine.) This way you can still safely drive the car, while you wait for the new tumbler to be delivered to the dealer.

Good luck.
