Nuki.io

Overview

Nuki.io is a smart lock solution that turns an ordinary door into a connected, keyless entry point. It focuses on the two things people care about most at home: security and convenience. The lock pairs with your smartphone, so you can open your door, share access and keep an eye on who comes and goes without ever handling a physical key. It also works alongside a growing range of accessories, from a keypad for PIN entry to a dedicated smart-lock cylinder, so you can build the exact setup your entrance needs. For anyone building a modern smart home, or simply tired of losing keys, Nuki is one of the most established options on the market.

How it works

Nuki installs directly over your existing cylinder lock, so there is no drilling and no need to replace your hardware. Once mounted, the smart lock connects to the Nuki app on iOS and Android through Bluetooth or Wi-Fi. From there you can lock and unlock remotely, create and revoke digital keys, and receive a notification every time the door is used. Nuki also plugs into the wider smart-home ecosystem, working with Amazon Alexa, Google Assistant and Apple HomeKit, so voice control and automation scenarios are within easy reach.

Features

• Remote locking and unlocking: control your door from anywhere through the app.
• Overlay installation: fits on top of your current lock without changing the cylinder or the key.
• Digital key sharing: grant permanent or temporary access to family, guests or service providers.
• Activity log: see exactly who entered and left, and when.
• Smart-home integrations: works with Alexa, Google Assistant and Apple HomeKit.
• Auto lock and unlock: the door can secure itself when you leave and open as you arrive.

Use cases

Nuki fits homeowners who want a safer, more flexible way to manage access. It is especially handy for households that regularly welcome guests, cleaners or deliveries, since digital keys can be shared and revoked in seconds. Landlords and short-stay hosts use it to give tenants temporary access without meeting for a key handover. People who often forget their keys gain a reliable backup, and anyone already running a connected home can fold Nuki into existing voice assistants and automations for a seamless daily routine.
