Nuki Smart Lock Pro vs Nuki Smart Lock Ultra comparison

Data from Amazon and official Nuki site.

2026 verdict

Two flagships from the same family, and the Nuki Smart Lock Ultra edges the Nuki Smart Lock Pro on owner reception, which is close to the whole story here because the specifications mirror each other. Both retrofit onto a European cylinder in minutes with no drilling, both run a built-in rechargeable battery rated around 6 months, both carry Wi-Fi and Bluetooth without a bridge, both support Matter and can join Thread with a border router, and both auto-unlock by geolocation with low battery alerts. That leaves price and feel as the deciding factors. The Nuki Smart Lock Pro is the more affordable of the two and gives up nothing measurable on the spec sheet, which makes it the sensible pick unless the Ultra's newer design and stronger owner feedback matter to you. Choose the Nuki Smart Lock Pro to save money on an identical feature set, and the Nuki Smart Lock Ultra for the best-received lock in the range.
