Locking/Unlocking Spells

Locking/Unlocking spells are elementary types of enchantments used to open or lock doors, locks, grates, caskets, cabinets and many others. Casting a spell of this kind may be more demanding of a sorcerer when another magic user has put a spell on the object that counteracts the warlock's or witch's effort.

Spells
The know locking or unlocking spells have been used in these occasions:

Unlocking Spells

 * Aliese, used by Merlin to open Valiant's door (Valiant).
 * Onstyrian, onbregdan, used by Merlin to enchant a door and make it move in the Lower Town. He did this to distract and to knock out a guard (The Mark of Nimueh).
 * Aliese duru rýne, used by Nimueh to open Bayard's door in order to replace one of the Mercian ceremonial goblets with her poisoned chalice (The Poisoned Chalice).
 * When Geoffrey of Monmouth found Merlin in the royal library looking for a book that could tell him how to slay a wraith, he asked the boy how he had got in there, since he himself had locked the door. Merlin told him that someone had opened it, but he had actually cast a spell to unlock the door (Excalibur).
 * Ic ia tóspringe, used by Merlin to open the door of Forridel's house (The Nightmare Begins).
 * Tospringe, used by Merlin blow off the door of the cell he was locked in (The Curse of Cornelius Sigan), blow off the gate at the end of a tunnel that led outside Camelot's walls (The Nightmare Begins) & to open the Troll's cabinet (Beauty and the Beast: Part Two). Also he used it in order to open Aredian's cupboard (The Witchfinder), Freya's cage (The Lady of the Lake) & used by Merlin to open a grate that closed the entrance to the siege tunnels under Camelot (The Sword in the Stone: Part Two); also it was used by Alvarr in order to open the door of Morgana's chambers and the door of his cell (The Witch's Quickening).
 * Unspanne þás mægþ, used by Merlin to free Freya from her handcuffs (The Lady of the Lake).
 * Ic bebeode þisne sweord þæt hé forcierfe þá bende þæra dracan. Un clýse, used by Merlin to free the Dragon. He cast it with a sword stolen from the Knights of Medhir; their blades had been forged by the Old Religion and using one of them, the young warlock could harness its power to his own and cut the chains with which Uther Pendragon held Kilgharrah prisoner (The Fires of Idirsholas).
 * Abricaþ benda, used by Merlin to open the chains. He failed because Morgause's spell was too powerful and the chains were resistant to magic, reflecting it and tightening when it was used on them, so he used Isen fæstnunga onlucan me which was useless, too, like Min strengest miht hate þe tospringan, (The Tears of Uther Pendragon: Part One).
 * The possible spell Kilgharrah used to break open the chains which bound Merlin (The Tears of Uther Pendragon: Part Two).
 * Onluc scrin, used by Merlin to open the box in which the Goblin was imprisoned (Goblin's Gold).
 * Atot-oilg, a chomlae, used by Grunhilda to try to open the grate's lock. Her spell failed because Merlin's magic was too powerful (The Changeling).
 * Ar-focraim uait, asndot-roilce, used by Grunhilda to angrily try to open the lock again, but the spell didn't work (The Changeling).
 * Lasa n-uile fil ocum ocus lasa nuile fil indium, ar-focraim atot-oilg! Lasa n-uile fil ocum ocus lasa nuile fil indium, atot-oilcfe, gìallfae dom, used by Grunhilda to blow off the gate. She focused all her energy on the gate since she couldn't break Merlin's spell on the lock (The Changeling).
 * Non-verbally, by Morgana to open the entrance of a tunnel that led into the Citadel (The Darkest Hour: Part Two).
 * Non-verbally, by Morgana to sneak into King Caerleon and Queen Annis' castle (His Father's Son).
 * Non-verbally, by Merlin to open the locked wooden chest in which Agravaine kept many magical grimoires (The Secret Sharer).
 * Non-verbally, by Emrys to open the door of the council chamber while Arthur was fighting the possessed Elyan (A Herald of the New Age).
 * Non-verbally, by Morgana to open and then close the doors of the throne room in the Fortress of Ismere at her passage (Arthur's Bane: Part Two).
 * Oncluce þe, by Ruadan to open the cell in which Sefa was kept. He used this enchantment again to unlock a door in the dungeons below Camelot while he was escaping with his daughter (Arthur's Bane: Part Two).
 * Aspring, cast by Merlin to open the door of the kitchens in which Uther's ghost had trapped Gwen and set a magical fire, with the intention of burning the Queen alive (The Death Song of Uther Pendragon).

 * Learh fearnancai, used by Merlin to lock Hengist in the cage with the Wilddeoren (Lancelot and Guinevere).
 * Fýrbendum fæst, used by Merlin to close the same cabinet, so that Jonas wouldn't notice that his potion had been replaced. Later on he used this spell again to lock the door of the council room so that Catrina true form would have been exposed (Beauty and the Beast: Part Two).
