Ugh, that's confusing. Many cars unlock the driver's door only by default (assuming using a keyfob) but have the option of setting it to unlock all doors. One neat thing about VW group cars (VW, Audi, etc) is the ability to use VAG-COM to reprogram a dizzying array of car functions. Other vehicles have this ability (BMW comes to mind) but require extremely expensive dealer-only tools to do it.
