Learn how to connect your Nuki Smart Lock to Apple HomeKit, control it with Siri, and set up automations. Step-by-step guide for Smart Lock Ultra and Pro 5th Gen.
Integrating your Nuki Smart Lock with Apple HomeKit unlocks a new level of convenience: you can lock and unlock your door using Siri, the Apple Home app, or even include it in automated scenes. Whether you own the latest Smart Lock Ultra or the reliable Smart Lock Pro (5th Gen), the process is straightforward once you follow the right steps. In this guide, we’ll walk you through everything you need to get Nuki HomeKit integration up and running in minutes.

HomeKit compatibility means your door lock isn’t just a standalone device — it becomes part of your entire smart home ecosystem. Imagine telling Siri to “lock the front door” as you leave, or having your lights turn on automatically when you unlock. With Nuki, this seamless integration is not only possible but also easy to achieve. Let’s dive into the prerequisites and setup.
What You Need Before You Start
To begin Nuki HomeKit integration, you’ll need several key components. First, ensure you have a compatible Nuki smart lock. The Smart Lock Ultra and Smart Lock Pro (5th Gen) both support Apple HomeKit natively via Bluetooth and Wi-Fi (through a bridge). If you have an older model, you may need the Nuki Bridge to add HomeKit functionality. Also, you’ll need an Apple device running iOS 12 or later, and an Apple Home Hub (such as an Apple TV, HomePod, or iPad) for remote access and automations.
Make sure your Nuki lock is powered, updated to the latest firmware, and paired with the Nuki app on your iPhone or iPad. You’ll also need a stable Wi-Fi network and Bluetooth enabled on your iOS device. Finally, ensure you have your Apple ID signed into iCloud to enable HomeKit sync across devices. Once everything is ready, move to the setup process.
- Compatible Nuki lock: Smart Lock Ultra or Smart Lock Pro (5th Gen) (with built-in HomeKit or via Bridge).
- Apple Home Hub: HomePod, Apple TV (4th gen or later), or iPad (with iOS 12+ and Home Hub enabled).
- Nuki app (latest version) and an Apple device for initial pairing.
Step 1: Enable HomeKit in the Nuki App
Open the Nuki app on your iPhone and select your smart lock from the device list. Tap the gear icon (Settings) and look for the “HomeKit” or “Apple Home” option. The exact location may vary slightly depending on your Nuki model, but it’s usually under “Integrations” or “Smart Home.” Tap on it and then select “Add to Apple Home.” The app will begin searching for your lock. If you’re using a Bridge, ensure it’s connected to the same Wi-Fi network.
When prompted, scan the HomeKit setup code that came with your Nuki lock. If you lost the code, you can find it in the Nuki app under the lock’s settings (it’s an 8-digit alphanumeric code). Once the code is accepted, iOS will ask you to choose a room (e.g., “Front Door”) and give your lock a name. After confirming, the lock will appear in the Apple Home app. This process usually takes less than two minutes.
- Keep your HomeKit setup code handy — it’s printed on the lock’s packaging and stored in the app.
- If you have multiple Nuki locks, repeat the process for each one.
Step 2: Configure the Lock in the Apple Home App
Now open the Apple Home app on your iPhone. You should see your new Nuki lock under the assigned room. Tap and hold the lock tile to access its controls. You can lock or unlock the door directly from the app. To customize settings, tap the gear icon (or the info button) on the tile. Here you can adjust notification preferences, such as when someone unlocks the door, or add the lock to scenes and automations.
For example, create a scene called “Goodnight” that locks your Nuki lock and turns off lights simultaneously. You can also set up automations based on time, location (when you leave or arrive), or sensor triggers. If you have a Nuki keypad-2-208683">Keypad 2 or Door Sensor, you can combine them for even smarter routines. Note that unlocking remotely requires an Apple Home Hub; otherwise, you can only control the lock via Bluetooth when in range.
Step 3: Use Siri to Control Your Nuki Lock
Once the lock is added to HomeKit, you can control it with Siri voice commands. Simply say “Hey Siri, lock the front door” or “Hey Siri, is the front door locked?” Siri will respond and execute the command. For security, Siri may ask you to confirm unlocking on devices without a locked screen. You can also use Siri on HomePod, Apple Watch, or Mac. This hands-free control is especially useful when your hands are full with groceries.
If you find that Siri isn’t responding reliably, check that your lock has a strong Bluetooth or Wi-Fi connection and that your Apple Home Hub is online. Also ensure that “Hey Siri” is enabled on your devices. Some users prefer to create a named scene (e.g., “Open Sesame”) to trigger multiple actions at once. With Nuki HomeKit integration, the possibilities are extensive.
- You can also use Siri to check the lock status: “Hey Siri, is the back door locked?”
- For security, you must authenticate with Face ID/Touch ID on iPhone before Siri can unlock the door from lock screen.
Troubleshooting Common Nuki HomeKit Issues
If the lock doesn’t appear in the Home app, first confirm that you’ve completed the Nuki app setup correctly. Restart both your iPhone and the Nuki lock (remove and reinsert batteries). Ensure your iOS device is on the same Wi-Fi network as your Nuki Bridge (if used). Also check that your lock’s firmware is up to date — you can update it via the Nuki app. If the setup code is not working, try entering it manually from the Nuki app settings.
Another common issue is “No Response” in the Home app. This usually indicates a connectivity problem. Make sure your Apple Home Hub is online and connected to the same Apple ID. For Bluetooth-only setups (without a Bridge), you must stay within Bluetooth range. Consider adding a Nuki Bridge or using a Wi-Fi dongle for the Smart Lock Pro (5th Gen) to improve range. If problems persist, resetting the HomeKit pairing and starting over often resolves them.
- Always keep your Nuki lock and app updated to the latest firmware for optimal HomeKit performance.
- Using a dedicated Apple Home Hub (like HomePod mini) improves remote access reliability.
Integrating your Nuki smart lock with Apple HomeKit is a straightforward process that adds a new layer of convenience and security to your home. Whether you choose the advanced Smart Lock Ultra or the proven Smart Lock Pro (5th Gen), you’ll enjoy seamless Siri control, smart automations, and peace of mind. Ready to make your entrance smarter?
