About the Door Key black filled icon
A classic door key sits inside a thin circle: a round bow with a hole in the center, a straight shaft and a notched bit with two cut teeth at the tip. It signals access, unlocking and protection, which suits login screens, password reset flows, real estate listings, rental and property apps and security sections of a site.
The key is centered vertically with even space inside the ring, and the teeth are cut as sharp steps rather than rounded notches. Group it with lock, shield and door icons; the circular frame lets it drop straight into round button slots.
This is the solid black filled version of the door key 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.
