Bluetooth Smart Lock Setup Guide¶

How to install, pair, and configure a Bluetooth smart lock in your UK home - compatible with uPVC, composite, and timber doors.

Choosing a Bluetooth Smart Lock for UK Doors¶

Bluetooth smart locks connect directly to your smartphone via BLE 5.0 or 5.1, offering hands-free unlock within 2 - 5 metres. The Nuki Smart Lock 3.0 Pro (£179) and Yale Linus (£129) are the two best-selling models in the UK. Both fit Euro-profile cylinders common on uPVC and composite doors. Nuki supports auto-unlock via geofencing, while Yale Linus integrates with the Yale Home app for remote access when paired with a WiFi bridge (£49 extra). Battery life averages 8 - 12 months on 4 AA alkaline cells. Over 1.2 million UK households now use Bluetooth smart locks, driven by the growth of smart home ecosystems.

Step-by-Step Bluetooth Pairing and Calibration¶

After mounting the lock body, open the manufacturer's app - Nuki uses the Nuki Smart Lock app, Yale uses the Yale Home app. Hold the smartphone within 1 metre of the lock, ensure Bluetooth is enabled, and press the pairing button on the lock (usually on the side or under the battery cover). The app will scan and discover the device within 10 seconds. Follow the calibration wizard: the lock will cycle through open and closed positions to learn the door's throw distance. Calibration takes approximately 2 minutes. Test the lock manually from both inside and outside. If the lock binds or makes excessive noise, adjust the mounting ring using the supplied shims - a common issue on doors that are slightly out of square.

FAQ¶

Do I need WiFi if my smart lock uses Bluetooth?: No - Bluetooth handles local unlocking. However, if you want remote access or voice control via Alexa, you will need a WiFi bridge such as the Nuki Fob or Yale WiFi Bridge (£49).
Will a Bluetooth lock work on my uPVC door?: Yes - all major brands support UK Euro-profile cylinders found on uPVC, composite, and timber doors. Verify the door thickness is between 38 mm and 80 mm.
Can multiple phones connect to one Bluetooth lock?: Yes - most apps allow up to 10 authorised users. Each person installs the app and receives an invitation from the primary account holder. For more information see our WiFi Smart Lock Installation Guide.
