Aqara Smart Lock U200 vs Nuki Smart Lock Pro

Aqara Smart Lock U200 wins with its lower price, IPX5 weather resistance, built-in fingerprint, keypad, NFC and Apple Home Key, and guest password features. Nuki Smart Lock Pro counters with a higher rating, 2-year warranty and built-in Wi-Fi in a sleek Euro-cylinder retrofit.

Included hardware. The Aqara ships with every unlock method built in. The Nuki is a minimalist interior motor: phone, watch and auto-unlock work natively, but keypad and fingerprint entry require separate accessories that raise the already premium price.

The Nuki Smart Lock Pro retrofits European profile cylinders only (the cylinder must accept a key from both sides), with no US deadbolt support. The Aqara Smart Lock U200 is a deadbolt retrofit with an IPX5 outdoor keypad, suiting exposed doors the non-weatherproof Nuki should avoid.

Both use built-in rechargeable batteries lasting about 6 months. The Aqara Smart Lock U200 adds AAA and USB emergency backups; the Nuki Smart Lock Pro has no backup power option, and some owners report battery or charging complaints.

Choose Aqara Smart Lock U200 for the complete keyless package at the lower price: fingerprint, codes, NFC, Home Key, guest passwords and all-platform support including IFTTT.

Choose Nuki Smart Lock Pro for a premium, better-rated Euro-cylinder retrofit with built-in Wi-Fi, fast quiet motor and hands-free auto-unlock, backed by a 2-year warranty.
