2017 22 ft Powerlite Toyhauler locked door opens by itself

[Srath]

I am stumped the side door on my trailer opens all by itself in the middle of the night. This is the 4th time it has happened. I repositioned my cameras so I can see if it got hit by a car or anyone screwing with it and it just opens itself. It does have electric code lock/unlock. Has anyone else had this problem? I have a video not sure if I did it right. Let me know.
