I just like to say, thanks to everyone for there help. This is the final outcome. I was with the locksmith for 3 - 4 hours and the key he made only worked for the doors , glove compartment and trunk. We tried everything with the ignition. From finnesse to brutal strength. No luck with either or in between. Finally I just called the Benz dealer and had them tow the car. The final cost is $550.00 including towing parts and labor. Sound right?
