    According to GM when you program a keyfob it automatically cancels out the keyfob that was already programmed to that car. So you have to reprogram it back in. That's what i tried to do, but everytime i'd program one in it would cancel out the other. My question is...how do you program two keyfobs to one car without canceling the other one out?

    you have to program them both in one cycle. Don't touch the ignition after doing the first, wait till after the second.

    ^^^^ yes...this...Once you're in programming mode, do the first one, then the second one right after.
