About the Keyhole black filled icon
A single keyhole drawn as a round upper opening that narrows into a long straight slot with a rounded base, the familiar profile of a European mortise cylinder. It reads instantly as locking, privacy and restricted entry, which makes it useful on login screens, password fields, privacy policy pages, locksmith and door hardware sites, and security slides in a product deck.
The composition is strictly symmetrical and vertical: the circle takes roughly a third of the height and the slot runs straight down from it with even stroke weight. Pair it with key, padlock and shield icons for a consistent security set. At small sizes keep the inner slot open so the silhouette stays readable.
This is the solid black filled version of the keyhole icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
