You used the wrong action in the intro conversation of your psyche locks sequence.
"Reveal psyche locks button" only displays the button to launch the psyche locks sequence next time the user goes to that place's talk topic list.
You should use "Psyche locks animations - Locks appear" instead, so that the locks appear at that time.
If you don't use that action, locks automatically appear at the end of this intro conversation.
