I did a search for this, but did not see anything under 6th gen. is the dealer the only one that can program a new key/Fob? i use to have the 5th gen and I know you could do it yourself.

INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-II.

CAUTION:
-After a new Intelligent Key-ID is registered, be sure to check the function.
-When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and Intelligent Keys for any other vehicles out of the vehicle before starting.

CONSULT-II can be used to check and delete Intelligent Key-IDs.

 

My buddy did mines 3 weeks ago, If I remember correctly....

1. you enter the car from the drivers side
2. hit the power door lock
3. you stick the key in the ignition and pull it out 10 times ( so in and out, in and out, etc )
4. The flashers will blink
5. you hit the door lock button on your remote

I think thats it, let me know if that doesnt work, I'll ask my buddy again
