So Keyless Go is the start stop button to start the engine. I might be wrong but I'm pretty sure it doesn't include Keyless entry. I believe Keyless Entry is only available on Xcellence models and above. Incidentally, as I understand it, all models have keyless go (start stop engine button)
Edit. Just check with the brochure from July which has all the first edition models. Keyless Go is standard on all cars. (Stop Start Button)
Keyless Entry and Go is only from excellence models and above.
