The Winged Keys, also known as Flying Keys, were keys that were presumably enchanted with a Flying Charm by Professor Filius Flitwick to guard the Philosopher's Stone. The keys were placed in a massive "flock" within the third of the Stone's Chambers, and only one of them would allow entry into the fourth chamber through a locked door that was made impervious to Unlocking Charms. The chamber also contained brooms, which could be used to retrieve the correct key, though the keys would scatter chaotically as soon as the brooms were used to lift-off.
