Confusion with Keyless Go on my 05 E500
I have a 2005 E500, and I am confused on the whole Keyless Entry / Keyless Go. Upon purchasing the car, the owner only had one key at the time(Regular MB key with chrome on the outsides) months down the line they found the second key(ALL black, it's shaped and looks different than the main key). On the driver door handle I only the tiny little black square, I do not have the larger transparent square near the middle of the handle. After reading lots of forums and articles, everyone was giving different answers and asking different questions. The main reason I am looking into all of this is to see if I can buy an MB Push to start button for my car, as I would like that feature, but being as it's an 05 it does not come with the car. I believe I HAVE to have the Keyless Go feature in order for the Push to Start button to work?
What classifies an MB car as having Keyless Go, and what is the different between Keyless Start, Keyless Go, and Keyless Entry?
Sorry if these are all noob questions, I for some reason am just very confused.
Will post VIN# if requested
Thanks all!

There were two styles of keys, the black one was the original one, but you could order a replacement and I think you could get it in the chrome case or move the innards from the black key to the newer style chrome key. The older MB's only had keyless go. I think Keyless entry is just having a fob, pretty much any car has that. Keyless start means you just press the button to start the car, but that's for newer models and it's a way to put in the feature at a cheaper cost, was never an option on the W211. Keyless go has sensors in all 4 door handles to lock and unlock the doors. Also locks/unlocks the trunk and gas cover. With keyless start in some of the cheaper newer models, they save money on the door handles and other external equipment and just have to sense the key for the start/stop function.




Keyless go is more than just the start button. It also have locking/unlocking by touching door handles. Than technology changes from year to year and when it comes to options, I never take anything for granted.
