The Anti-Alohomora Charm was an anti-unlocking spell invented by Blagdon Blay sometime in the early 17th century. His house had been broken into nineteen times through use of the Unlocking Charm, and so he invented this spell to counteract it. This may be the spell used on the door of the defence teacher's office.
