We have tried both of our keys in our 98 ML320, neither will turn. We have shaken the steering wheel to see if it is a steering column lock. No luck. Odd thing is, the same time the key won't turn the right side signal and lane marker also quit working. Any suggestions??

There is nothing I know of (short of an incorrect key) that should keep the key from turning, so I would guess it's the lock cylinder or the steering wheel lock assembly itself that's jammed.

Our's sometimes won't turn and is stubborn. Turning the wheel and re-inserting the key always worked.

If one of the front wheels is bound against a curb you must pull extra hard on the steering wheel to take the pressure off the lock. Two hands maybe required, and I have even heard of the need to jack the car up to release the pressure on the wheel!

I was worried about breaking the key off. I was twisting it quite hard! But, a stiff kick to the front tires must have loosened the bind on the steering wheel and freed up the key. Thanks for your posts.

These MLs just get more ridiculous with every tale.

"Yeah, my key won't turn in the ignition."

"Have you tried kicking your tires?"
