Professional installation costs £50–150 if you’re uncomfortable with DIY.
Smart Home Integration
All five locks above work with Alexa or Google Home via an optional bridge. If you’re committed to Apple HomeKit, ensure the model has HomeKit Secure Router compatibility.

FAQ: Smart Door Locks UK
Q: Are smart locks secure?
Yes. Modern smart locks use 128-bit encryption and secure authentication protocols. Your mechanical key backup ensures you’re never locked out. Most insurance providers recognize smart locks as equivalent to or better than traditional locks.
Q: Can I install a smart lock on a rental property?
Absolutely. Locks like the Nuki Smart Lock Pro are specifically designed for renters because they mount over existing deadbolts without modification. You can remove them when you move.
Q: How often do I need to change batteries?
Most smart locks last 6–18 months on a set of AA/AAA batteries, depending on usage. You’ll receive low-battery alerts through your app, giving you time to replace them before lockout.
Q: What happens if my WiFi goes down?
Bluetooth locks work independently of WiFi—your phone can still unlock the door as long as you’re nearby. WiFi-only locks require a bridge device. Most modern locks default to local Bluetooth authentication with optional remote WiFi control.
Q: Can I share access with guests?
Yes. All major smart locks allow temporary access codes or time-limited smartphone permissions. Perfect for Airbnb hosts, service personnel, or family visiting from abroad.
