Steering wheel lock or key lock?

[curbill]

On my wifes 300sd she has a hard time starting the car. When she goes to turn the key it will not go to the right. You have to jiggle the steering wheel quite a bit until the key will go thru the detent. Is this fixable or just the nature of the beast. I tried and it did the same thing for me. Our other MBs do not have this problem.
