Press on the lock and unlock on the keyfob till you see the red light on the key blink. That's how you change it.
Thanks, worked perfect on my 2012 base, as noted by others here, but my wife said she never uses her keyfob to open the door (keeps it in purse).
So I tested it by using the button only on the door latch and it worked the same: one push opened all doors!
Again, thanks for the great tip.
