"There are many ways to pass through locked doors in the magical world (see the Fire-Making Spell, Gouging Spell, and the Reductor Curse) where you wish to enter or depart discreetly, however, the Unlocking Charm is your best friend."
— The introduction to the entry on this spell in Book of Spells.[src]

The Unlocking Charm, also known as the Thief's Friend (Alohomora) is a charm that opens mechanical locks that are not protected by magic. It is also able to open doors locked by Colloportus. There is a spell called the Anti-Alohomora Charm which is used to counteract this spell.

Descriptions of this spell are written in numerous books, including the first volume of the Standard Book of Spells series, where it is described in chapter seven [1] and a spellbook that can be found in the Hogwarts Library.[2]

History

Although it is unknown who invented it (the spell was created in Africa) it was brought to Britain and hence to the world in the 17th century by Eldon Elsrickle. He used it to terrorise London, stealing from homes of Muggles and wizards alike, until Blagdon Blay invented an Anti-Alohomora Charm.
