Aqara U100 vs U50 Comparison
access method
The U100 offers biometric entry via a high-precision fingerprint reader that stores up to 50 unique prints. It also supports Apple Home Key, remote passwords, one-time local passwords, and a mechanical key. The U50 replaces the fingerprint sensor with a physical keypad for code entry. It supports Apple Home Key, remote passwords, one-time local passwords, temporary visitor passwords, and a mechanical key. If you prefer not to carry keys or rely on biometrics, the U50 keypad provides a reliable alternative. However, the U100 adds the convenience of touch-free fingerprint access for hands full of groceries.
connectivity
Both locks rely on Zigbee 3.0 connectivity to function. This means you must have an Aqara Zigbee 3.0 hub to enable remote features like app control and third-party integrations. Without a hub, local operations like fingerprint or key entry still work. The U50 additionally highlights Matter support when paired with a Matter compatible Aqara hub, offering broader interoperability with other smart home ecosystems. The U100 data does not explicitly list Matter support. If you are building a future-proof smart home with Matter devices, the U50 provides that specific compatibility layer out of the box.
battery life
Power efficiency differs between the two models. The U100 uses four AA 1.5V batteries and is rated for up to eight months of operation. The U50 also uses four AA batteries but requires 6V batteries and is rated for up to six months. Both include batteries and feature a USB-C port for emergency charging. The U100 provides a longer battery lifespan, reducing the frequency of replacements. If you want to minimize maintenance and battery changes, the U100 is the more efficient choice for your daily routine.
build quality
Both locks feature a zinc alloy body and comply with BHMA Level 3 safety standards. They both include a built-in gyroscope for auto-locking and a Do Not Disturb mode. The U100 carries an IP65 rating, offering protection against dust and low-pressure water jets. The U50 carries an IPX5 rating, which protects against water jets but not dust. The U100 also withstands temperatures up to 151°F, while the U50 withstands up to 150.8°F. The U100 offers slightly better environmental sealing against dust and extreme heat.
key management
The U50 includes a specific feature for existing homeowners: a rekeyable cylinder. You can remove the lock cylinder and have a locksmith adjust the pins to match your existing 5-pin key, allowing you to continue using your original keys. The U100 data does not mention rekeying capabilities. If you want to avoid changing all the locks in your house when installing a smart lock, the U50 allows you to keep your current keys. The U100 does not provide this convenience in its listed specifications.
Choose the right Aqara deadbolt for you
Users wanting fingerprint access and auto-lock
The U100 includes a fingerprint reader for up to 50 prints, offering quick biometric entry without a keypad. It features an auto-lock function driven by a built-in gyroscope, securing the door automatically after you close it. This model also provides a longer battery life of up to 8 months compared to the U50.
Buyers needing a physical keypad for codes
The U50 features a physical keypad for entering access codes directly, which is useful if you prefer not to use biometrics. It supports temporary passwords for visitors and one-time local passwords when internet is unavailable. This model also allows for easy rekeying of the cylinder to match existing keys using a standard locksmith service.
Those prioritizing weather resistance for outdoor use
The U100 carries an IP65 rating for its zinc alloy body, providing better protection against dust and water jets than the U50's IPX5 rating. It also withstands a slightly wider temperature range from -31°F to 151°F. This makes the U100 a more durable choice for exterior doors exposed to harsh weather conditions.
