I went to the dealer and they can program a few things:
1. The key into the tailgate can raise or lower the window by turning the key in it (I know that was already mentioned, but the dealer needs to activate it)
2. Dealer can activate it so when holding the "unlock" button, it will lower all side windows
3. Dealer can turn off seat belt chimes (took me 3 attempts while the first 2 times at the same dealer they told me it is "illegal")
4. My dealer never told me I had remote start but to test it, quickly push lock 3 times then hold it down the 4th time till the lights blink and it will start after that. To go along with this, unlocking or locking the car will turn off the engine
