So you are trying to retrofit KeylessGo to your car? This will be a very challenging and expensive project. Not only will you need all the parts (several ,modules, antennas, shifter, door handles and new keys) you will also need some new coding. Unless you (or someone you know) is an expert MBZ electronics hacker, you'll probably spend at least several thousand US$ just on dealership labor to help with the coding. The parts will be much more than that. My advice is that if you want a car with KeylessGo, sell yours and buy one that came that way.
