The Aqara Smart Lock U100 serves as the flagship deadbolt in the lineup, engineered specifically to replace traditional thumb-turn deadbolts with advanced digital intelligence. Built around an IP65 weather-rated zinc alloy body, this deadbolt complies with rigorous physical security standards to resist rain, freezing weather, and tampering. The headline feature for Apple households is native Apple Home and Apple Home Key integration. Family members can unlock the door simply by tapping an iPhone or Apple Watch against the keypad reader, functioning even when the device battery is exhausted. The unit runs on four included AA 1.5V batteries that deliver up to eight months of regular operation, backed by an exterior USB-C port for emergency temporary charging.

Beyond tap-to-unlock convenience, this model incorporates a high-precision biometric fingerprint reader capable of storing up to 50 unique fingerprints. When paired with an Aqara Zigbee 3.0 hub, the deadbolt enables remotely configurable passwords via the Aqara Home app, voice assistant control through Amazon Alexa and Google Home, and broader smart automation setups using IFTTT. The internal gyroscope detects door positioning to trigger automated locking after closure, while a Do Not Disturb mode silences keypad sounds during nighttime hours. Families exploring alternatives like a hornbill smart lock often prefer the U100 for its immediate Apple Home Key responsiveness and local biometric accuracy.

This deadbolt suits busy households that prioritize fast fingerprint authentication, physical backup keys, and seamless Apple Home integration. It gives way to the U300 when your door requires an all-in-one lever handle rather than a separate deadbolt, or to the B50 if you prefer direct Wi-Fi management without buying an extra hub.

The Aqara Smart Lock with Handle U300 is a comprehensive smart lever lock that combines a motorized latch and an ergonomic exterior handle into a single piece of hardware. Designed for single-bore entry doors, garage access portals, or interior utility rooms, the U300 is built with Matter over Thread technology. This standard enables simultaneous connection to major ecosystems including Apple Home, Google Home, Amazon Alexa, and SmartThings, delivering reduced power draw and faster responsiveness. When paired with a Thread-enabled Apple hub such as a HomePod mini or Apple TV 4K, users enjoy full Apple Home Key access with a simple tap of an iPhone or Apple Watch.

Biometric authentication on the U300 relies on an enlarged 160 by 160 pixel fingerprint sensor array located right on the handle pivot. Offering double the surface area of standard 128 by 96 sensors, it captures rich ridge detail to authenticate authorized users in under 0.3 seconds. All sensitive biometric data is protected locally with AES encryption. The lock operates for up to ten months on four AA alkaline batteries, and dual exterior USB-C ports provide emergency backup power. Through Bluetooth connectivity in the Aqara App, users can fine-tune auto-lock timing and activate a Scheduled Quiet Mode to silence latch operation during sleeping hours.

This integrated lever suits homeowners outfitting side doors, attached garages, or modern entryways that do not have an upper deadbolt cutout. It yields to the U100 or B50 when your door setup uses a separate traditional deadbolt above an unlatched handle.

The Aqara Smart Lock B50 delivers connected deadbolt security without requiring any dedicated hub or bridge hardware. Equipped with built-in Wi-Fi 6 operating on standard 2.4GHz bands, the B50 links straight to your home network, allowing you to lock, unlock, and inspect status logs remotely through the Aqara Home app, Amazon Alexa, or Google Home. Sized at 3 by 2 by 5.5 inches, this compact deadbolt provides multiple access paths, including an illuminated backlit keypad, app controls, voice commands, shareable offline passcodes, and standard physical keys.

Security is reinforced through thoughtful digital and physical defenses. An anti-peep keypad function allows users to enter random numbers before or after their genuine passcode, preventing onlookers from deciphering the code. The lock also includes failed attempt lockouts, a night latch mode, automated locking, and Do Not Disturb scheduling. Rated at IPX3 for weatherproofing, the B50 withstands temperature extremes ranging from -31 degrees Fahrenheit to 150 degrees Fahrenheit. The deadbolt runs up to six months on four AA batteries, features a USB-C port for emergency power, and integrates directly with Aqara smart doorbells for front-porch viewing and one-tap guest entry. Homeowners evaluating accessible options such as a tapo smart door lock will appreciate the B50 for its standalone network independence and direct smart home integration.

The B50 is the optimal choice for rental properties or busy families wanting reliable numeric keypad entry and remote Wi-Fi monitoring without external accessories. It steps aside for the U100 if your family demands rapid biometric fingerprint scanning and Apple Home Key tap unlocking.

Best for: Homeowners pairing hardware with standalone deadbolts

Pros

• Reversible handle for left or right swing
• Fits standard 2-3/8 and 2-3/4 backsets
• Modern finish matches U100 and U50
• Certified durable construction

Cons

• Non-locking passage lever without motorized bolt

The Aqara Entry Door Handle is a mechanical exterior door lever crafted to bring visual and physical balance to your entryway. When installing a standalone smart deadbolt like the U100 or B50, pairing it with an older, mismatched lower latch can diminish your home’s exterior aesthetic. This non-locking passage lever provides a modern, uniform appearance that matches the finish and profile of Aqara’s digital hardware. Designed with a fully reversible exterior lever, it installs easily on both left-handed and right-handed swinging doors.

Installation follows standard residential door dimensions, accommodating 2-3/8 inch (60mm) or 2-3/4 inch (70mm) backsets and door thicknesses between 1-3/8 inches (35mm) and 1-3/4 inches (45.5mm). The hardware includes all required installation components and meets stringent industry standards for mechanical durability, security, and surface longevity. While functioning as a mechanical passage lever without motorized locking, the product listing references Zigbee protocol compatibility within the broader Aqara product framework. Homeowners upgrading entryways who have also considered solutions like a tuya smart door lock can utilize this handle to maintain a clean, cohesive exterior design alongside an electronic deadbolt.

This handle is the right pick for anyone installing an Aqara smart deadbolt who needs a reliable, matching lower latch mechanism. It gives way to the U300 if your door configuration requires a self-contained motorized smart lever rather than separate latch and deadbolt components.

Best for: Children and seniors needing effortless tap entry

Pros

• EAL5+ financial-grade encryption
• Zero batteries or charging needed
• One-to-one secure pairing
• Instant induction tap unlock

Cons

• Single lock pairing per card
• Can be misplaced like physical key

The Aqara NFC Card for Smart Locks provides an effortless physical tap-access solution compatible with Aqara electronic deadbolts and smart locks, including the U100, U50, U200, U300, and U400. Operating through contactless radio frequency induction, this compact key card requires no batteries, charging, or internal wiring. It provides an intuitive alternative for household members who do not carry a smartphone or who have trouble remembering numeric keypad codes.

Advanced security architecture keeps credential handling safe. Each card contains a built-in EAL5+ financial-grade security chip that protects access data against digital cloning and unauthorized duplication. Pairing operates on an individual basis: one card pairs with one lock at a time, ensuring strict, isolated credential oversight. With sensitive induction calibration, tapping the card against the lock’s NFC reader area provides immediate unlocking. Enrolling and revoking cards is handled within the Aqara companion app, making it practical for managing access for short-term guests, service workers, or babysitters.

This card is best for elementary school children, elderly relatives, and temporary visitors who need a physical token for door entry. It gives way to biometric fingerprints and digital passcodes when users prefer to unlock doors without carrying any physical items.
