Came across the procedure while coping diagrams at the dealership today!

You still have to have the "magic" box, but all they do is erase ALL the keys from the system! Then it will take the first two keys used in it.

Makes sense from an assembly line point of view. Put the locks in, grab a box off hte shelf and plug it in. Give the keys a twist and they are automatically programmed in!

 

Or just call a locksmith. Most now have the module to do the same thing.
