Best Overall: Aqara Smart Lock U200 (¥1,299)

Aqara’s U200 is the most versatile smart lock available in China. It supports Apple Home Key (tap your iPhone or Apple Watch to unlock), Matter (works with any Matter-compatible platform), and traditional fingerprint/code/passkey entry. The retrofit design installs over your existing deadbolt, so no door modification needed. The U200 is the only lock we tested that natively supports both Apple HomeKit and Matter.

JD Verified Buyer — Zhang M. ★★★★★ “The Apple Home Key feature is fantastic—just tap my iPhone and the door unlocks, no app needed. Installation took about 20 minutes over my existing deadbolt. The fingerprint sensor is fast and accurate. The battery lasted 5 months before the low-battery warning. Aqara’s Zigbee hub is required for remote access.”

Tmall User — Chen L. ★★★★☆ “Great lock but setup with the Aqara app was a bit fiddly—needed to update firmware first. The Matter integration with Google Home works after setup. Fingerprint works 9/10 times, occasional failed reads with sweaty fingers. Overall very happy with the purchase.”

Best Value: Xiaomi Smart Lock D100 (¥899)

Xiaomi’s D100 covers all the essentials: fast fingerprint recognition (0.3 seconds), multiple unlock methods, and solid Mi Home app integration. The C级 (Grade C) lock cylinder is the highest security rating in China. The built-in doorbell function adds convenience.

Verdict

The Aqara Smart Lock U200 at ¥1,299 is our top pick for its Apple Home Key support and Matter compatibility. Apple users will find it genuinely transformative—unlocking with your phone or watch without any app interaction. Xiaomi ecosystem users should get the Xiaomi Smart Lock D100 at ¥899 for its excellent Mi Home integration.

Overall Score: 8.6/10
