Hi there,

Do you have the intelligent key system? Key and fob in one?

Ok,

Sorry to say but you cannot program this without the dealer scan tool. Unless you can locate a mobile locksmith with the correct computer you can't break into the security system and program the keyfob or the key. This is a complicated process that requires first getting the info from the body control module, then it has to be put into the computer to get a pin number to break into the security on the ecm. Then you can program, but need the scan tool to do it.

I hope this helps, I am sure it's not what you want to hear and I am truly sorry for that, but, it's the only way it can be done.
