"Is there a way for me to get through security then lock my chastity device myself and lock the key in the chrono vault?"
Sure if you have owner access to the ChronoVault.
"Then i was thinking it opens about an hour before my return flight leaves so I can take the device off before going through security. Is this possible?"
The timer can be set to any amount of time.
"Will I need a computer to lock the chrono vault? Will I need a computer to open the chrono vault?"
You need a PC to set the timer, either locally or remotely, and close the vault. The vault opens without the need for a PC when the timer has elapsed.
