I purchased a new key for my W220 from the dealer and I just realized the Keyless Go doesn't work with this new key. Everything else works as all the buttons on the key and putting the key in the ignition to start the car all work. Do you need to program the keyless go somehow to sync with the car?

You might have purchased a standard key as opposed to a keyless go key. I have one of each for my car. The keyless go key is more expensive and must be programed for your car.
