I have 2002 Mercedes Benz c240
We lost key fob to turn the car on. So we thought better and cheaper don't go dealership lol in the end we went to dealer to order us the key.
Before we ordered ignition switch, the key fob not working Vin did not match it.
He did wash the fuses a day before. So we had no luck and for new key fob bur still does not turn?
