I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

Hello and welcome! I'm Billy and i will assist you with this.

My apologies for the delay, thank you for your patience.

Eventhough the key issue was sorted, i will include the details on your key's operation, battery replacement etc.... so you keep with you for future reference:

As for the starting problem, it could be the starter, the wiring or the ignition (command...)
In your case, the most common problem causing this, would be corrosion at the connectors of the ABS/BAS control unit. This problem is so common, that MB had to release a technical service bulletin. I will include the bulletin, which has the details necessary so you proceed accordingly.
