Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. When this occurs do you get any sort of warning on the dash when you try cranking the engine? Do you have a spare key that you have tried?
Sorry for the delay in getting back with you. I was not online earlier. It sounds like you have a failing electronic ignition switch. These are a common failure and will have issues picking up the key when it fails.
No problem Larry. Keep in mind also that even after you rate my service I can continue to help you. Have a great weekend.
