Aqara Smart Lock U200 vs Nuki Smart Lock Ultra

Aqara Smart Lock U200 wins with its much lower price, IPX5 rating, built-in unlock methods and guest password toolkit. Nuki Smart Lock Ultra counters with a higher rating, 2-year warranty and the fastest, most premium hardware in the Nuki line.

Approach. The Aqara ships complete: fingerprint, keypad, NFC and Home Key built in for a deadbolt retrofit. The Nuki is a premium interior motor for European cylinders, hands-free auto-unlock and app control out of the box, keypad and fingerprint as extra-cost accessories.

The Nuki Smart Lock Ultra retrofits European profile cylinders only, not US deadbolts, and is not weather-resistant. The Aqara Smart Lock U200 retrofits deadbolts and its IPX5 exterior keypad tolerates rain-exposed installations.

The Nuki Smart Lock Ultra is the better-reviewed lock, described by owners as Nuki's best yet with only minor install quirks. The Aqara Smart Lock U200's rating trails due to calibration friction and some reports of grinding after a year.

Choose Aqara Smart Lock U200 for the complete keyless package at a fraction of the price: fingerprint, codes, NFC, Home Key, guest passwords and every platform including IFTTT.

Choose Nuki Smart Lock Ultra for the most refined Euro-cylinder retrofit available: fast, compact, better-rated hardware with built-in Wi-Fi, Matter support and a 2-year warranty, at a premium price.
