Fob Re-learn?

Last week, I purchased a '05 STS4. The dealer, however, only had one fob so he ordered me a new fob (#2.) Well, today the dealer programmed the new fob, but he did it to read as fob #3. Consequently, the fob will open the doors and start the car, but it will not recall the #2 memory positions. So, how do I retrain the fob to be the #2 fob?

Although this is my first post on this forum, I am a member of the corvetteforum.com ('05 Black/Red/Black Corvette) and the avalancheforum.com ('07 Black/Tan Avalanche.) From my previous experience, the forums are full of useful information. For example, today I brought in the TSB number for the tranny software update and now the tranny shifts smooth as silk. Thanks everybody!!!

As soon as I get some pictures taken, I'll post them.
