adding keyless go to 2010 e550
https://mbworld.org/forums/w211-amg/...-key-hole.html
I dont have keyless go but want to add it. I know when I walk up to my car with my key fob and touch the handle it unlocks. Does this mean my key is keyless go ready and that I should just be able to click a keyless go switch into my igniton? If so--whats the part number!
Incorporating any MB features in a heavily computerized car like the W212 is a complex task, one of the few people most MBWorld forum members recommend for that is Steve at https://mbworld.org/forums/members/1384-mbenznl.html he can provide you a kit or a few times a year he visits the US for installs.
Good luck and keep us posted on your progress and the cost.

You definately have Keyless Go and your car should have come with the button, make the dealer give you one.
