Problem Description and Possible Solution
Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.

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.
