HAve not fixed it yet. MEchanic said I must show proof of ownership, etc to order parts. But, same issue, key won't engage unless I wiggle, twist, the key and then hold my breath.
Today, May 27, 2012.
I purchased this car Oct 2011 with 20,000 less miles.
This is the 3rd time that the ignition key became "stuck", unable to turn the ignition. This time, I cannot manage to find a way to turn the ignition key to the ON position.
I've tried rocking the car, simultaneously jiggling the key while rocking the locked steering steering wheel counter-clockwise, then clockwise, then counter, then clock, repeat until I am exhausted.
As soon as possible, I'll GO TO MERCEDES and ask them the cost to replace the tumbler matching the existing, same key. I already have an order in for a NEW KEY, factory direct.
I figure I should replace both, the ignition key and the tumblers. They're both probably worn beyond acceptable working condition.
