my fob on a pontiac G3 is not locking/unlocking the doors, although pressing the buttons on the fob, I press lock it will trigger the car alarm to turn on, pressing the unlock button on my fob causes the turn signals to blink 2x, but no door locks.

What is your question?

Once I tried to get the vehicle to get into TPMS learning mode, I put in the key, turn it to on (without starting) then pressed the lock/unlock buttons for 10 seconds expecting to hear the horn beep twice, did not happen, after that the locks would not work at all, have to do it manually.
