Smart Lock Integration with Alexa Google¶

How to connect your UK smart lock to Amazon Alexa, Google Assistant, and Apple HomeKit for voice control and smart home automation.

Voice Assistant Compatibility of UK Smart Locks¶

Major UK smart lock brands support at least one voice assistant. The Ultion Keyturn WiFi (£279) works with both Amazon Alexa and Google Assistant, allowing voice commands such as 'Alexa, lock the front door'. The Lockly Secure Plus (£249) is unique in supporting all three ecosystems: Alexa, Google Assistant, and Apple HomeKit. The Yale Conexis L2 (£199) requires the Yale WiFi Bridge (£49) for Alexa integration. Nuki 3.0 Pro (£179) supports Alexa and Google Assistant via the Nuki WiFi Bridge (£79). Security-conscious users should note that voice unlock is disabled by default on all platforms - you must enable it manually in the app. According to a 2025 YouGov survey, 38% of UK smart lock owners use voice commands for locking, but only 12% use voice to unlock due to security concerns.

Setting Up Alexa and Google Routines¶

To connect your smart lock to Alexa: open the Alexa app, tap 'Skills & Games', search for the lock brand (Ultion, Lockly, Yale, Nuki), and enable the skill. Link your lock account when prompted. For Google Assistant: open Google Home, tap 'Add > Set up device > Works with Google', and select the brand. Apple HomeKit users simply scan the HomeKit code (included with Lockly Secure Plus) using the Apple Home app. Once linked, create routines such as 'Lock up at 10 PM' or 'Unlock when I arrive home' using geofencing. For safety, Alexa requires a verbal PIN to unlock - set this in the Alexa app under Smart Lock settings. Google Assistant requires voice match for unlock commands. Routine-based locking can reduce forgotten-lock incidents by up to 70% according to Yale's own research.

FAQ¶

Can I unlock my door with Alexa without a PIN?: No - all UK smart locks require a verbal PIN for voice unlock as a security measure. Lock commands do not require a PIN.
Does Apple HomeKit work with UK smart locks?: Only Lockly Secure Plus offers native HomeKit support. HomeKit provides end-to-end encryption and works with Apple Watch and Siri.
Will my routine work if WiFi goes down?: No - voice commands and routines require an active internet connection. The physical key or keypad code still works during an outage. For more information see our Smart Lock Vacation Mode Guide.
