Outline vertical door key with a round bow and notched teeth at the tip
About the Key black outline icon
A single door key stands upright: a large circular bow with a small hole at its center forms the base, a slim straight shank runs up the middle, and the tip is cut into three squared notches on one side. It signals access, permission, unlocking and ownership, which makes it a natural fit for login and password fields, API key settings, hotel and rental listings, locksmith services and membership or premium unlock states.
The round bow carries most of the visual weight at the bottom, balancing the thin shank so the shape stays stable at small sizes, and the stepped teeth give it a recognizable silhouette in a toolbar. Pair it with padlock, shield and fingerprint icons in a security set, and render it at 24px or larger so the notches survive.
This is the black outline version of the key icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
