Free download of a smart door lock isometric 3D icon, ideal for home security, access control, and smart home visuals.
Free to download, this isometric 3D smart door lock icon is perfect for smart home apps, home security dashboards, access control systems, and connected device visuals. Its modern design works well in UI mockups, presentations, websites, and product illustrations focused on digital security and automation.
Every Smart Door Lock detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.
It suits smart home apps, home security dashboards, access control systems, connected device visuals and smart home visuals. It also appears in the Cybersecurity & Privacy pack.
Sizes on offer are 1024, 512 and 256 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
Free for personal and commercial projects. On the free plan, credit Thridy wherever the icon appears: a website footer, video credits, an app's about screen, or a README.
