Some doors are locked. There is a option to pick lock in order to open it. I do suggest watch a fast tutorial about lock picking in VEIN.
Sometimes it resets after you went offline so the doors need to be picked open again. Find as many lockpicks as you can!

Not all buildings have locked doors all the way around, fences for instance can be climbed over and unlocked from the other side without a lockpick
