Locks on veranda door question

Can someone tell me what kind of locks there are on the veranda door on the fantasy? Hoping that one lock is high up. Have two children and are concerned that they will go outside without first asking? Thanks

I don’t know about the Fantasy, but the Dream had high locks and a difficult handle as well. I felt perfectly safe with my children.

Fantasy is the same, high locks and tricky handle.

I could barely figure out how to get the door open (and I was on the cruise for my 25th birthday)…
