New Key From Dealer,But Keyless Go Don't work

Before I go back to the dealer , I am going to ask here, because I know some one will know the answer.

I had A new key made for my car by the dealer with my vin # tru the dealer a bought it from.

Well I got the key Friday and it works ,I can lock and unlock the doors with the buttons , when I hit unlock two times the windows and sun roof will open and on lock the second time I press lock the windows and sun roof will close.

But my Keyless Go Don't work when I try it , Question Is What Is The trick or setting to get KEYLESS GO to work On My 05 S500 W220

Thank you for any help in this matter

Sounds like something is wrong the fob or there is a certain procedure to program a new fob so its 100% functional

On keyless-go cars after 2003 that use a "smart-key" the key track must be validated with a DAS laptop.

ONLY 2 keyless-go keys can be used.

Either that or the dealer ordered a normal smart key instead of a smart key with keyless go.
