Not quite sure I understand what you are asking. If you press and hold, for example, the left sliding door button on the remote, the left sliding door opens and the driver's door unlocks. If you press and hold the right sliding door button on the remote, the right sliding door opens and the front passenger door unlocks. If you want to unlock the back hatch or all the doors, then press the unlock button twice, but if you don't open a door within 30 seconds then everything automatically relocks. Finally, if you press and hold the unlock button twice, all the windows roll down. I don't know about the power rear hatch because I don't have one.
