Narrative:
Startup and taxi to runway was uneventful. All checklists were complied with. We were cleared for takeoff on runway xx. At approx 600 ft the whole cabin became very loud with the sound of air. I looked back in the cabin and the passengers were pointing towards the door. They were all safely buckled in their seats. We told the tower we needed to return for landing. They asked why and the PNF (pilot not flying) told them for a door issue. We made left traffic; ran the before landing checklist and landed. After taxi in and shut down we inspected the door. All seemed fine; with the door operating normally. We contacted our mechanic and also the service center we use for the aircraft. The door closed normally; with the door warning light extinguished when the door was closed and locked. The PNF then stated he suspects he may have closed but not fully locked the door. When he closed it; it came up faster and with more force than he anticipated. This subsequently disrupted his routine locking of the door. Then; on initial climb out when the aircraft started to pressurize the door came open. After further conferring with our mechanic and the service center; we decided to continue our flight unpressurized just to be on the safe side. The flight was uneventful. We then brought the aircraft to the service center for them to inspect the door and the warning light and rigging. They could not find any issues. Going forward; I am determined to always double check the door and visually confirm the green bars that show when the door is locked.
