Aqara Smart Lock U100
VERDICT
If you can't decide between a keypad lock, a fingerprint lock, or an Apple Home Key lock, get the U100—it has them all. The fingerprint reader is incredibly fast (under 0.5 seconds), and the build quality is surprisingly robust for the price. It bridges the gap between Apple and Android users perfectly.
The Big Picture
Most smart locks force you to choose one unlocking method. The Aqara U100 gives you options. You can tap your iPhone (Home Key), scan your thumbprint, type a code on the matte keypad, use the physical emergency key, or even use an NFC card. It’s a "fail-safe" lock designed to ensure you never get locked out.
👆 Biometric Speed
The Tech: A 3D semiconductor fingerprint reader embedded in the handle.
Performance: It reads your print naturally as you grab the door handle. It has a success rate of over 98%, even with slightly wet hands, and stores up to 50 fingerprints locally (encrypted).
⚡ Zigbee 3.0 & Matter
Built for automation.
Connectivity: Unlike Wi-Fi locks that eat batteries, the U100 uses Zigbee (requires an Aqara Hub for remote access) or Bluetooth (direct to phone). This allows the 4 AA batteries to last up to 8 months. It also supports Matter, making it future-proof.
✅ The Pros
- Versatility: Fingerprint + Home Key + Keypad + Physical Key.
- Price: Significantly cheaper than Schlage Encode Plus.
- Design: Modern, compact, and matte black finish resists fingerprints.
- Auto-Lock: Built-in gyroscope locks the door instantly when closed.
❌ The Cons
- Hub Required: Needs an Aqara Hub (like M2 or E1) for remote control via Google/Alexa (HomeKit works via Bluetooth/Apple TV).
- Aesthetics: The "handle" design is unique but might not fit traditional home styles.
- Installation: Slightly more complex than a simple retrofit lock.
🤔 Should you buy it?
YES if you want the convenience of fingerprints AND Apple Home Key without breaking the bank.
NO if you don't want to buy an extra Hub for remote access (get the Wi-Fi based Schlage Encode Plus).
