About the Keyhole black outline icon
A classic keyhole drawn as a large circular opening sitting above a tapered slot that flares out to a flat base, the shape you see cut into an old door plate. It reads instantly as locking, privacy and restricted entry. Use it on login and password screens, privacy settings panels, access-control dashboards, escape-room or mystery posters, and locksmith or home-security websites.
The round head fills roughly the upper half of the shape, and the slot widens outward to a flat base, giving a balanced silhouette with even stroke weight throughout. It pairs naturally with key, padlock and shield icons. Keep it at 24 px or larger so the narrow slot stays visibly open.
This is the black outline version of the keyhole icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
