Lock Magic was a type of magic involving the manipulation of either mechanical or magical locks. Common during the Magic Kingdom Levianta's era, it was used as both a means to keep out intruders and secure entry.
Locking spells allowed the user to magically lock doors and other openings to prevent break-ins, repeating and presumably enhancing the effect of ordinary locks. By the same token, the spell could be used to unlock doors as well as pick magical locks. When used on a normal mechanical lock, a spellcaster could unlock doors with a simple flick of their finger while opening it. Simple lock magic was generally easy to learn.
- When Allen Avadonia attempted to open a door by reciting "Open Banana", the Demon of Lust humorously questioned if it was a lock spell.
