Upon taking off out of ZZZ at a couple hundred feet I got a CAS (Crew Alerting System) message alerting me that the RH Crew Door was open and unlocked. When I got a second to check it; it appeared closed securely to me with the handle all the way down and the door tight. Given the fact that until that moment the door was indicating closed and locked and my own observation seemed to confirm that; I believed it to be a sensor issue and elected to continue the flight. I had no further issue until I was less than a minute from landing. At this point the door came open. The door was still tight against the air frame due to the wind forcing it closed but it was clearly unsecured. I landed with no further incident and taxied to the gate.
