Nuki Smart Lock Ultra vs SwitchBot Lock

Full Smart Door Locks comparison in 2026

Data from Amazon and official Nuki and SwitchBot sites.
2026 verdict
Nuki Smart Lock Ultra wins on rating, warranty, connectivity and guest codes.
It is the better-reviewed lock, covered for 2 years versus 1, connects natively over built-in Wi-Fi, Bluetooth and Thread for hub-free Matter, HomeKit, Google, Alexa, SmartThings and Home Assistant access, and its accessory keypads support one-time and periodic guest codes. SwitchBot Lock answers with a lower entry price, NFC support out of the box, adapters that fit almost any cylinder, and a modular path to keypad, fingerprint and face-recognition entry, though remote access and Matter demand a SwitchBot Hub. Both are interior retrofits for European-style cylinders around 6 months per battery cycle. The flagship Nuki Smart Lock Ultra takes the win comfortably; tight budgets and odd cylinders favor the SwitchBot.
