FOB Training problems
2002 Z06
I have three separate key fobs that came with my car. None of them work. I have tried holding lock and unlock outside of the car for a while with no outcome. I have also tried going inside and going to the FOB Training on the dash, but when I hit reset again to go to the next screen that's supposed to tell you to "hold lck & unlck", that screen doesn't appear. Only code code my car pulls is C1214 and my AC temperature sensor. I have looked up other issues but cannot find anything like mine.

The battery is from 11/16, I'll check voltage on it and be sure it's right battery spec
brand new batteries in all of the key fobs

That is why the FOB's cannot be retrained. 
There is no communications over the serial data buss to the Remote Function Adapter (RFA) which is the receiver for the FOB's (and TPMS for cars that are equipped with them). Check fuse #27 in the fuse box in the passenger foot well. If it is not the fuse then it most likely is the RFA has failed, but you need to do some diagnosing before just replacing parts.

NO. Not saying that at all. The Z06 did NOT come equipped with TPMS. That feature is turned OFF in the BCM for 2001 - 2004 Z06 at the factory.
Your issue is most likely fuse #27 or the RFA module itself is bad or for some reason (damaged wiring??) not getting voltage at the RFA. Those conditions cause the B0 - RFA NO COMM message when you pull the codes.
Start with checking fuse #27 in the passenger foot well fuse box (behind the toe kick at the end of the foot well).
