AI Verdict
A $100-$149 zinc alloy deadbolt with Apple Home Key, Matter, and multi-ecosystem support, requiring an Aqara hub for remote access.
This lock is a strong contender if you're already invested in the Aqara ecosystem or specifically want Apple Home Key without a fingerprint reader. Its zinc alloy build and BHMA Level 3 rating provide security, but the reliance on an Aqara hub for remote functions and an Apple hub for full Home Key sharing adds complexity and cost.
If you need integrated fingerprint access or a simpler setup without multiple hubs, look for models with built-in Wi-Fi and biometric sensors.

What Buyers Say
Many users are drawn to the U50 because it's one of the more affordable smart locks that supports Apple Home Key, which works even if your iPhone or Apple Watch battery is dead. However, a recurring point is the necessity of an Aqara Zigbee 3.0 hub for remote access and full integration with other smart home platforms like Google Home or Alexa. Some buyers also found the setup for sharing Home Keys with family members through Apple HomeKit to be confusing, often requiring an additional Apple Home Hub. The absence of a fingerprint sensor, a feature found on its sibling U100, is a frequent comparison point.
“Man, I bought this for Home Key and that part works like a charm, even when my watch is dead. But seriously, why do I need another hub just to unlock it when I'm not home? And sharing the Home Key was a headache, had to dig out an old HomePod. Still, for the price, it's doing the job.”
Common Praise
- Apple Home Key works seamlessly with iPhone and Apple Watch for quick entry.
- The ability to rekey the cylinder to match existing physical keys is a practical feature.
- Keypad lights up clearly and the deadbolt mechanism operates smoothly.
- Battery life extends up to 6 months, and the USB-C emergency charging port is a useful backup.
- Integration with various smart home ecosystems (with an Aqara hub) is broad.
Common Complaints
- Remote unlocking and advanced smart home automations are locked behind needing a separate Aqara hub.
- Sharing Apple Home Keys with family members requires an Apple Home Hub, adding another device to the setup.
- The lock's physical size is larger than expected, sometimes requiring door modifications during installation.
- No fingerprint sensor, which is a missed convenience for some users coming from other smart locks.
- The NFC card for tap-to-unlock is not included and must be purchased separately.
Ownership Tips
- The auto-lock feature, enabled by the gyroscope, consistently engages the deadbolt after the door closes.
- The keypad is responsive, and the anti-peep password feature (adding random digits before/after your code) works as advertised.
- Battery notifications through the Aqara app are timely, preventing unexpected lockouts.
- The 'Do Not Disturb' mode successfully mutes lock sounds, which is useful for late-night entries.
- While the lock body is zinc alloy, the interior mechanism can feel a bit plasticky to the touch.
Frequently Asked Questions
Does the Aqara U50 work without an Aqara hub?
You can use basic functions like keypad entry and Apple Home Key (via Bluetooth) without an Aqara hub. However, remote control, Matter, Google Home, Alexa, and IFTTT integrations require an Aqara Zigbee 3.0 hub.
Can I share Apple Home Key access with family members?
Yes, but sharing Apple Home Key with additional residents requires an Apple Home Hub, such as an Apple TV 4K or HomePod.
What happens if the batteries die?
The lock is powered by 4 AA batteries with a 6-month life. If they run out, there's a USB-C port for emergency charging, or you can use the physical key.
Is the Aqara U50 difficult to install?
Installation involves replacing a standard deadbolt. Some users report it's straightforward, while others found the lock's larger size required minor door frame adjustments or chiseling.
Does this lock have a fingerprint reader?
No, the Aqara U50 does not include a fingerprint reader. This feature is typically found on the higher-end Aqara U100 model.
Buying Guide
When you're looking at smart locks, think about how you actually want to get in your house. Do you want to tap your phone, use a code, or just use a regular key? Also, consider if you need to control it when you're not home, because that usually means you'll need an extra piece of equipment called a hub. Don't forget to check your door's thickness and backset, as some smart locks are bulkier than traditional ones.
Apple Home Key Support
This means you can unlock your door by simply tapping your iPhone or Apple Watch against the lock, similar to using Apple Pay. It's super convenient because it works even if your phone's battery is dead, turning your Apple device into a digital key.
Zigbee Connectivity
Zigbee is a wireless communication standard for smart home devices. It's energy-efficient, which helps your lock's batteries last longer. However, to get the most out of Zigbee (like remote control or connecting to other smart home systems), you usually need a central 'hub' that translates Zigbee signals to your home network.
BHMA Level 3
This is a security rating from the Builders Hardware Manufacturers Association. Level 3 is the lowest residential security grade, meaning it meets basic standards for strength and durability. Higher levels (like Level 1) offer more robust security, so Level 3 is suitable for most standard home uses but not high-security needs.
Alternatives
If you need a fingerprint sensor for quick entry, search for smart locks with integrated biometric authentication. If you want remote control without an extra hub, look for models with built-in Wi-Fi.
