How to Choose

• Security rating: Check for Sold Secure or other certifications. Higher-rated locks offer better protection against forced entry.
• Compatibility: Ensure the lock fits your door type (UK standard deadbolt, mortice, etc.). Some locks are designed for specific door preparations.
• Connectivity: Decide if you want Wi-Fi, Bluetooth, or both. Wi-Fi allows remote access without a hub, but can drain batteries faster.
• Smart home ecosystem: Choose a lock that works with your existing system (Apple HomeKit, Google Home, Amazon Alexa, or Matter).
• Power source: Most smart locks use batteries. Check battery life and whether there's a low-battery warning or backup power option.
• Installation: Some locks are DIY-friendly, while others require professional installation. Consider your skill level and the complexity of the lock.
