Aqara Smart Lock U200 vs Nuki Smart Lock Pro

Full Smart Door Locks comparison in 2026

Updated October 2026
Data from Amazon and official Aqara and Nuki sites.
2026 verdict
For a front door with a standard US-style deadbolt, the Aqara Smart Lock U200 is the better value smart lock of the two, and it typically costs less than the Nuki Smart Lock Pro.
It carries a fingerprint reader, a keypad with one-time, periodic and anti-peep codes, NFC and Apple Home Key, adds an IPX5 weather rating and keeps AAA and USB backup power behind its rechargeable battery. The Nuki Smart Lock Pro counters with better owner reviews, a two-year warranty against one and Wi-Fi and Bluetooth in addition to Thread, and it is the more compact lock on the inside of the door, though codes and fingerprints need Nuki's keypad accessories. Both speak Matter and work with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. Go with the Aqara Smart Lock U200 for built-in entry methods at a lower price, and with the Nuki Smart Lock Pro for a European cylinder and the better reviewed lock.

What the differences mean

Keypad and fingerprint

The Aqara Smart Lock U200 has its fingerprint reader and keypad built in, plus NFC and Apple Home Key. The Nuki Smart Lock Pro needs the Nuki Keypad for codes and the Keypad 2 for fingerprints, and neither NFC nor Home Key is on the list.

Door standard

The Aqara Smart Lock U200 goes over a US-style deadbolt, while the Nuki Smart Lock Pro is a retrofit for European cylinders that owners say needs a slightly protruding cylinder and a key that works from both sides.

Backup power

Both use a rechargeable battery rated for about 6 months, but only the Aqara Smart Lock U200 can fall back on AAA batteries or USB power. When the Nuki Smart Lock Pro runs flat, the physical key is the way in.

Connectivity

The Nuki Smart Lock Pro combines Wi-Fi, Bluetooth and Thread. The Aqara Smart Lock U200 relies on Thread for its smart home connection and needs a border router for remote control.

Weather and warranty

The Aqara Smart Lock U200 is rated IPX5 and the Nuki Smart Lock Pro carries no rating. Warranty goes the other way: two years for the Nuki, one for the Aqara.

What owners say

Both groups of owners like a retrofit that keeps the existing key and a lock that talks to Apple Home and the other big platforms. The details diverge. Aqara Smart Lock U200 owners praise Apple Home Key with an Apple Watch, a fast fingerprint reader and a feature list they find generous for the money, but many report calibration that keeps failing, a confusing app, the need for a Thread hub, and locks that grind or stop locking reliably after about a year. Nuki Smart Lock Pro owners single out a strong, quick motor, fast charging and built-in Wi-Fi that they did not have to pay extra for, especially those coming from the Go. Their caveats are the cost once the fingerprint keypad is added, installation requirements for the cylinder and key, and a few batteries that stopped charging.
