I had a 2006 R171 that did that. What I had to do was to insert the key in the ignition and while in the ignition press the lock button and the unlock button on the key (I assume that you have the electronic key). Sometimes more than once. It resets the key. Try it and see if that works.
Same problem occurred for me a few days ago. Any ideas? If the ignition switch needs replacement, the old key will still be usable?

Had exactly the same problem and finally solved it by removing the tumbler switch assembly. I took it to a key shop locally and they performed some magic on the tumbler. Re-installed the unit on the car and have never had the problem again.
I asked the shop technician why it happened and he explained that the tumblers will sometimes need to be readjusted. He filed the tumblers to match the key, which is why he requested a key that showed little or no wear.
He also warned me that it must be fixed or it will get to the point where the key will not rotate the tumbler lock, which is really big trouble, especially if you happen to be in a remote location.
Good luck and best regards. Chuck
