turbo... that's all 100% normal...

1) passenger/hatch::: they are assuming that you are opening the door to put something in and being nice enough to unlock the drivers door for you as well (also if you left your keys on the passenger seat, you might lock urself out)
2)drivers door::: they dont need to have the rest open because the driver is now in the seat (technically)
3)and with the door open::: it is likely that you will lock the door and keep your keys in the ignition or in the car...

-- just pull the handle when you have the door open and hit the switch, it will lock if the handle is pulled
