10 Best Smart Locks

The Nuki Smart Lock Ultra is a sleek, compact smart lock designed for Euro Profile doors, making it a strong choice if you want a secure and fast smart locking solution. Its standout feature is the new motor, which is about three times faster than previous models, helping you lock or unlock your door quickly. It comes with a premium security cylinder included, ensuring a high level of physical security and compatibility with many door types. Installation is straightforward and tool-free, guided by the Nuki app, and can be completed in about 15 minutes, which is great for those who want a hassle-free setup.

Connectivity options include Bluetooth, Wi-Fi, and Matter, so it integrates well with popular smart home systems like Alexa, Google Assistant, and SmartThings. You can control the lock remotely via the app, allowing you to unlock your door from anywhere, assign access to others, and use smart features like Auto Unlock and Night Mode. Power-wise, it uses an internal rechargeable battery that can be charged directly on the door with a magnetic cable, fully charging in just two hours and lasting for months on a single charge. This saves you the trouble of frequent battery replacements.

The price might be higher than simpler smart locks, and its compatibility is mostly suited for Euro Profile doors, so it may not fit all door types. Also, although the installation is easy, some users may still find managing app permissions and settings a bit complex if they are new to smart home devices. This smart lock is well-suited for users seeking a fast, secure, and versatile smart lock with strong smart home integration, especially if they have compatible doors and want remote access capabilities.

The Schlage Encode Plus Smart WiFi Deadbolt is designed for homeowners who want reliable, convenient remote access and strong security.

It supports Apple HomeKit and Apple Home Keys, allowing easy tap-to-unlock with an iPhone or Apple Watch, and it works with Alexa and Google Assistant for voice control, adding more hands-free convenience.

Installation is straightforward and doesn’t require any wiring; the Snap ‘n Stay design holds the lock in place while you work, fitting most standard doors. The lock uses batteries (not included), so you’ll need to keep an eye on power but won’t have to worry about complicated wiring.

In terms of security, Schlage is a trusted brand known for strong deadbolts. You get features like customizable notifications and lock history for peace of mind. This lock is a strong option if you want keyless entry combined with modern smart home integration and easy installation. However, if you prefer a lock without reliance on apps or voice assistants, or want included batteries, you might want to consider those points before buying.

The Ultion Nuki Smart Lock 2025 is a strong choice for UK homeowners looking for a secure and smart solution, especially if you have PVC or composite doors. It boasts a 3-star PLUS security rating, which means it offers robust protection against break-ins. Connectivity is solid with built-in Wi-Fi allowing you to control the lock remotely via an app, so you can let guests in even when you're not home. It also integrates easily with popular smart home systems like Alexa, Google Home, and Apple Home through the Matter protocol, making it convenient if you already use these platforms.

Installation is suitable for doors over 55mm thick and comes with hardware, so it should fit most front doors without professional help. The chrome finish and modern design add a sleek look.

Access methods are flexible and user-friendly, offering several options: app control, a physical key, a keyfob, a wireless keypad with fingerprint recognition, and voice commands. This variety makes it convenient for different household members and guests. The auto-lock and auto-unlock features add hands-free convenience, especially useful when your hands are full or you’re arriving home. Although remote Wi-Fi control can raise some privacy and security concerns if not properly set up, the Ultion Nuki Smart Lock 2025 remains a secure, smart lock that works well with UK door types and offers versatile access options.
