How to make a copy of key fob

Hi,

This really isn't a DIY on this vehicle. To make things even more difficult, there was a change to the frequency used (AM or FM) based on production date. If you look through this technical service bulletin, it describes how to add one or two new fobs and update the system. However, it requires specific tooling. The attached pics correlate with the directions. Note that this indicates a fob that is inoperative. I realize that isn't the case, but the procedure for reprogramming is relevant.

I wish I had an easy answer, but this is the procedure:
