The Anti-Alohomora Charm (incantation unknown) is an anti-unlocking spell, that acts as a counter-charm to the Unlocking Charm.[1]


Invented by Blagdon Blay sometime in the early 17th century. His house had been broken into nineteen times through use of the Unlocking Charm (Alohomora), and so he invented this spell to counteract it.[1]
