My Golf does this. Put your hand behind the handle and it unlocks driver's side. Repeat this and it will unlock the rest of the doors. The first few days I had the HRV, I'd walk up and put my hand behind the handle twice and get in while the rest of the family stood at their doors and looked at me angrily amused. The good news is that now I'm opening the door for my wife 100% of the time as this unlocks the doors for everyone!........Many cars you can tap, say the inside of the door handle, twice and it will unlock all the doors.
