Lock Unlock

The lock-unlock icon represents the ability to unlock or secure something. It is commonly used to indicate that a user can unlock a secure resource or protect their data.

The lock-unlock icon is often used in software applications where security is important, such as online banking, e-commerce, or password management tools. For example, it may appear in a login form to indicate that a user can unlock their account.

From a UX perspective, the lock-unlock icon communicates that a user has control over security or protection. It helps users understand that they can unlock or secure their data.

Lock Unlock is one of 799 icons in SmartIcons Glyph, made by SmartIcons and released under CC BY SA 4.0. It is drawn on a 17 × 16 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds LockUnlockIcon to components/icons/si-glyph-lock-unlock.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed LockUnlockIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Lock Unlock icon, or any of 799 SmartIcons Glyph icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 17 × 16 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Lock Unlock", so screen readers say what it does.

Yes. LockUnlockIcon passes every SVG prop to the svg element, so <LockUnlockIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.
