10 Best Smart Locks

The Weiser Powerbolt 3 Satin Chrome is a keyless electronic deadbolt designed mainly for residential use, offering secure code-based access without needing Wi-Fi or smartphone apps. It supports up to 25 user codes plus temporary one-time codes, which is great for families, guests, or service workers. This lock uses a 10-button backlit keypad, making it easy to use day or night and in different weather conditions.

It features a strong ANSI/BHMA Grade 3 certified deadbolt and Weiser's SmartKey technology, which allows for quick re-keying if needed. The auto-lock feature with a customizable timer adds convenience by ensuring your door locks itself after a set time. Installation fits standard North American door sizes and requires typical door preparations, so you likely won't need professional help.

The lock runs on batteries, offering about 12 months of life, which means low maintenance but you'll need to replace batteries eventually. However, it lacks Wi-Fi or Bluetooth connectivity, so you won’t get remote control or integration with smart home systems like Alexa or Google Assistant. This makes it a solid choice if you want a straightforward, reliable keyless deadbolt without the complexity or cost of a fully connected smart lock. It suits anyone looking to upgrade home security on front, back, or side doors without the need for advanced tech features.

The Weiser Halo Satin Nickel WiFi Smart Lock is a touchscreen keypad deadbolt designed for keyless entry, making it a strong choice for front doors or rental properties like Airbnb. It connects directly to your home Wi-Fi, so you can lock or unlock your door remotely using the Weiser app without needing extra hubs or subscription services. You can store up to 250 passcodes, which is great for sharing access with family, guests, or service providers, and you receive notifications each time a code is used.

Security is solid with 128-bit encryption, BHMA Grade 2 certification, and a 20-minute fire rating, plus the included SmartKey technology lets you re-key the lock yourself if keys are lost. The lock works with both Android and Apple phones, but voice controls through Alexa or Google Assistant currently only work with Android devices. Power comes from 4 AA batteries, which are included, and installation is straightforward with all necessary hardware provided.

Some users report the app can be a bit tricky to navigate and occasional connectivity hiccups. Also, while the lock supports many access codes, managing them might be overwhelming if you’re not comfortable with apps. The satin nickel finish and metal build give it a modern look and durable feel. This smart lock suits those who want convenient remote control and strong security without complicated setups, especially renters and homeowners wanting flexible access options.

The Aqara UWB Smart Lock U400 is a deadbolt designed for home security with several modern convenience features. It stands out with its Ultra-Wideband (UWB) technology that allows hands-free unlocking as you approach, which is very handy if your hands are full or you're wearing gloves. This feature works best with Apple devices running the latest software and requires a compatible Apple home hub. Besides UWB, it supports many other entry methods including fingerprint, touchscreen passcode, physical key, NFC card, and voice control via Alexa, Google, HomeKit, and more, giving you flexibility in how you unlock your door.

The lock uses a rechargeable lithium battery that lasts up to six months on a single charge and can be recharged without removing it, minimizing downtime. It also alerts you when the battery is low. From a security standpoint, it is BHMA-certified, meaning it meets recognized standards for reliability and strength, and has an IP65 rating for protection against dust and water, making it suitable for outdoor use.

Thanks to the Matter over Thread technology, it connects smoothly to multiple smart home platforms for faster and more stable performance, but a compatible Thread-enabled hub is needed for proper integration. The Aqara app adds useful features like auto-locking, night latch mode, and integration with Aqara cameras for enhanced home monitoring. The advanced UWB unlocking is limited to certain Apple devices and hubs, which could restrict its full potential for some users. Installation involves replacing an existing deadbolt and may require some DIY skills. Also, some accessories like NFC cards are sold separately. This smart lock is a suitable choice for homeowners deeply embedded in Apple’s ecosystem who want a hands-free, secure entry with multiple backup options. It also fits those looking for strong security and smart home compatibility across different platforms, although users without Apple devices or those preferring a simpler setup might find some features less accessible.
