"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 in the Book of Spells[src]

The Unlocking Charm, also known as the Thief's Friend (Alohomora) is a charm that unlocks and opens doors and windows[2] that are not protected by magic. It is also able to open doors locked by the Locking Spell (Colloportus).

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 the Anti-Alohomora Charm.

Before Alohomora, the most popular unlocking spell was Portaberto (used to splinter a lock from a door; though known to occasionally leave a smoking hole where the key should have gone) and, before that, Open Sesame (which ripped doors from their hinges and tore them into firewood). All of these were more rudimentary and by far less subtle than Alohomora.

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[3] and a spellbook that can be found in the Hogwarts Library.[4] This spell is also taught in Charms class to first years at Hogwarts school of Witchcraft and Wizardry and is one of the first spells students learn.

Counter-charm

There is a spell called the Anti-Alohomora Charm which is used to counteract this spell. Magical locks also existed and were placed on several doors, but could be unlocked with this charm.
