ML w163 Start Error. no Crank, no start. Simple check. 

If your car suddenly refuses to crank, don't panick. It can be as simple to fix as ABC.
Don't go too deep trying to check starter itself. The first step is to perform a relay swap with its initial relay and check to see if problem is solved. The next step is to see if any fuses are blown as on the video demonstration. The next is to make sure your key is not worn out, cracked casing, or partially open as indicated on the video. It could simply be the transponder chip that shook due to a loose key casing. Please look at video to understand what I mean by "key casing" and correct me if the word used is wrong and confusing.
Thanks for watching.
After opening my key casing, fitting the transponder properly, the car started. It simply means the transponder shook inside the key casing.
