Hi, my name is***** fuse #9 in the main fuse box under the hood. If the fuse is good you will need to replace the electronic ignition switch or the electronic steering lock. If the keys still lock and unlock the car chances are that the steering lock has failed. If the keys will not unlock the car the electronic ignition switch is the likely problem. Both of these items will require the Mercedes dealer to replace and program with the Star Diagnosis computer.

Let me know if you have any questions.
