CLK 320 1999 My key won't turn?
 

Hey,

Hey guys I need some advice. My clk 320 will not let me turn my key after i put it in the ignition.

I hooked the battery up to some jumper cables and I tested the battery voltage.

The mechanic down the street told me I would need to go to a dealer and bring a title for the car to fix it. Something about a tumbler???

Please help,
Andrew
