10 Best Smart Locks

The Ultion Nuki Smart Lock 2025 is designed for PVC and composite doors up to 55mm thick, making it a great choice if you have these door types and want to upgrade security without changing the entire lock. It offers strong security with a 3-star PLUS rating, combining Ultion’s trusted mechanical lock with advanced electronic features for high protection. Its built-in WiFi allows remote locking and unlocking from anywhere, which is handy if you need to let guests in while away.

Compatibility with popular smart home systems like Alexa, Google Home, and Apple Home (via Matter) means you can control your lock using familiar devices and voice commands. The auto-lock and auto-unlock features add ease, especially when your hands are full or you’re in a hurry. Access options are flexible: you can use a physical key, app, keyfob, keypad, or even fingerprint recognition, covering different user preferences. The lock runs on a lithium-ion battery, included with the unit, so you won’t need extra purchases.

Installation comes with all necessary hardware, but the lock is sized for thinner doors under 55mm, which might not fit thicker door frames. This smart lock effectively blends strong security with modern smart features, making it well suited for UK homes seeking a secure and convenient upgrade on compatible door types.

The Schlage BE499WBCAM716 Encode Plus is a solid choice for anyone looking to upgrade to a smart lock with strong remote control features. It connects directly to your home Wi-Fi, so you can lock or unlock your door from anywhere using the Schlage Home app. This is great for managing access for family, guests, or service workers, with support for up to 100 unique codes and notifications about lock activity. It’s compatible with Apple HomeKit, allowing you to tap your iPhone or Apple Watch for quick access, and it also integrates with Alexa and Google Assistant for convenient voice control.

Installation is user-friendly, requiring just a screwdriver and fitting standard door sizes, with no need for wiring. The lock runs on batteries (not included), which means you should keep an eye on power levels to avoid lockouts. Security-wise, it offers keyless entry and an auto-lock feature, adding to peace of mind. The bronze finish looks classic and sturdy, fitting well with many home styles.

While it’s feature-rich, its price and higher rank among deadbolts might be a consideration if you’re on a budget. Also, some users may find the app setup or managing multiple locks a bit complex at first. This smart lock blends convenience, security, and modern tech smoothly for everyday home use.

The Simpled SF-SPS Weatherproof Slim Series Smart Lock is a versatile option for anyone looking to upgrade their door security with smart features, especially if you live in the UK. It offers a wide range of unlocking methods—including fingerprint, passcodes, phone app, Bluetooth, smartwatch, NFC, physical keys, and integration with Alexa or Google Home via a WiFi bridge. This variety makes it flexible for different users and situations, whether for homes, rentals, or offices. The lock supports easy sharing of access through an app, allowing you to customize who can enter and when, which is great for trusted guests or temporary access.

It’s designed for retrofit, meaning it can be fitted to most door types without major changes, which simplifies installation. The outside panel is weatherproof to handle rainy UK conditions, though the inside panel must stay dry, so be mindful about where it’s installed indoors. Power comes from included alkaline batteries, so you won’t need hard wiring, but battery life depends on usage. A handy auto-lock feature adds convenience and security by locking the door automatically after closing. The lock’s build materials (brass and aluminium) and modern silver design should fit well with many door styles.

The sensitivity of the inside panel to moisture means it’s not fully weatherproof, which could limit placement options inside. The product comes with a 2-year warranty from a London-based company, providing additional peace of mind. This lock is well-suited for users who want flexible, tech-friendly access control with solid weather resistance and straightforward installation, particularly within the UK climate.
