Choosing between smart deadbolts comes down to which details matter most at your door: the access terms named in the lock, the finish, door-handing information, and listed price. Among smart home electronics, the Aqara U100 and Aqara B50 are both new zinc-alloy electronic deadbolts, but they take notably different approaches in color, named functionality, and cost.
Quick verdict
Pick the Aqara U100 Smart Lock when you want the gray matte look, universal/reversible door handing, and the fingerprint, Apple Home Key, and HomeKit terms in its name. Pick the Aqara B50 when a black lock with Smart Wi-Fi, Bluetooth, and keypad wording is the closer match and the lower listed price is the deciding factor. The listed-price gap is $45.

Where each lock fits best
The Aqara U100 fits a gray-hardware plan. Its gray matte finish is a direct visual differentiator, while its universal/reversible handing makes it the more specific choice for shoppers considering door-handing details. The title also brings together fingerprint, Apple Home Key, HomeKit, and keyless terminology, giving this lock a distinct set of named features.
The Aqara B50 fits a black-lock plan with a lower listed price. Its model name specifically identifies Smart Wi-Fi, Bluetooth, and keypad operation, and it is also a new zinc-alloy electronic deadbolt. For a shopper deciding primarily between the two listed prices, the B50 is the lower-priced route without moving away from the Aqara brand or zinc-alloy construction.
Product notes
Aqara U100 Smart Lock Fingerprint Apple Home Key HomeKit Keyless Deadbolt Gray
The Aqara U100 is the fit for a shopper drawn to the fingerprint, Apple Home Key, and HomeKit wording in its name, along with a gray matte finish. It is an electronic, keyless zinc-alloy deadbolt with universal/reversible door handing, and it includes hardware and a key. That combination makes a clear case for doors where reversible handing matters and gray hardware is the preferred look. Its concrete tradeoff is the higher listed price in this comparison. Choose the U100 when its named access options, gray finish, and universal/reversible handing matter more than the $45 listed-price gap.
New Aqara B50 Smart Wi-Fi & Bluetooth Keypad Electronic Deadbolt Lock Black
The Aqara B50 makes sense when the lower listed price is central to the decision and a black lock suits the door. Its full name identifies it as a Smart Wi-Fi and Bluetooth keypad electronic deadbolt, while the model is listed as B50. Like the U100, it is new and made from zinc alloy, keeping the comparison focused on the named lock functions, finish, and price rather than construction material. The black color is its main limitation for shoppers aiming to match gray hardware. Select the B50 for its Wi-Fi, Bluetooth, and keypad focus at the lower of the two listed prices.
Final choice by use case
Choose the Aqara U100 for a gray matte deadbolt, universal/reversible handing, and its fingerprint, Apple Home Key, and HomeKit naming. Choose the Aqara B50 for a black Smart Wi-Fi and Bluetooth keypad electronic deadbolt at USD 59.99. Both are new Aqara zinc-alloy locks, so the final decision is chiefly about the named feature set, door-handing detail, finish, and listed price.
