In your manual it tells you how to turn the auto lock feature off. I hated everytime someone was in back I would forget to unlock doors so I just disabled the AutoLock function. It was easy and now the doors are not locked unless I push the button for them too. I am also in and out of my truck all the time so I would get P/O when I would jump out of the truck and walk around to the other side and the door was still locked. Lazy yes but when you buy a $40K vehicle it is because we are lazy to begin with. (Auto Everything!!)
