2008 Mercedes sprinter USA

[techterr]

Hello,
Has anyone made a spare key for a 2008 Mercedes Sprinter? I have made copies of the older keys with no problems, but I went to try and make a spare key for a 2008 Mercedes Sprinter and failed miserably... I tried reading data, any data, such as logging into the ECM or any other module with AVDI and it wouldn't see any of the modules... Changed over to the Dodge commander and it at least saw the modules.. But when I tried to open the special function/key learning it doesn't find a skim or win module... The key looks like a DAS2 flip key with an infared port. Does anyone have any ideas as to where the key info is stored on this vehicle?
Thanks in advance for any and all ideas on this...
Tim
