About the Keyhole black filled 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 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.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
