Nuki Smart Lock Ultra vs SwitchBot Lock

Full Smart Door Locks comparison in 2026

Data from the official Nuki and SwitchBot sites.
2026 verdict
Two takes on the retrofit smart lock: the Nuki Smart Lock Ultra is the stronger pick over the SwitchBot Lock, thanks to built-in Wi-Fi, Matter over Thread and a longer warranty.

It also leads on the keypad-based one-time and periodic codes and comes with a battery you do not swap. The SwitchBot Lock still has a case: it adds NFC tag unlock, an optional face-recognition keypad, and owners fit it to an unusually wide range of cylinders, including surface-mounted ones. Its motor is the weak point, since it can struggle with a stiff latch, and the CR123A cells drain fast for some. Pick the Nuki Smart Lock Ultra if you want a polished lock that talks to Apple Home, Google Home and Alexa on its own, and the SwitchBot Lock if you are renting, have an awkward cylinder or already run SwitchBot devices.

What the differences mean

Remote access and smart home

The Nuki Smart Lock Ultra has 2.4 GHz Wi-Fi built in and supports Matter, with a Thread border router in the mix, so Google Home, Alexa, Apple Home and SmartThings connect straight to it. The SwitchBot Lock is Bluetooth only, so every one of those platforms needs a SwitchBot Hub, and Matter needs the Hub 2.

Power

The Nuki Smart Lock Ultra has a built-in rechargeable battery, while the SwitchBot Lock takes 2x CR123A cells. Both are listed at about 6 months, but neither has a backup battery, and SwitchBot owners report the cells draining faster than that.

Size

The Nuki Smart Lock Ultra is a compact 57 x 58 mm unit on the inside, while the SwitchBot Lock measures 111.6 x 56 x 73.2 mm. The weight is the same, but the SwitchBot is the bulkier thing on the door.

Ways to unlock

Both use a keypad accessory for codes and fingerprints. The SwitchBot Lock also lists NFC tag unlock and a Vision Keypad for face recognition, while the Nuki Smart Lock Ultra has neither. The Nuki is the one with one-time and periodic passcodes listed, which the SwitchBot is not.

Warranty

The Nuki Smart Lock Ultra carries 2 years against 1 year for the SwitchBot Lock, which matters for a motorised device that moves a bolt many times a day.

What owners say

Owners of both locks agree that installation is quick, a guided app walks you through it, and keeping the existing cylinder and key is a big part of the appeal. From there the stories split. Nuki Smart Lock Ultra owners, many of them coming from earlier Nuki models, describe a faster, more compact and more premium lock, praise its Apple Home setup by QR code and its support, and mostly complain about the cost, a slightly fiddly cylinder length setting and the fact that keypad, fingerprint and NFC are separate accessories. SwitchBot Lock owners single out how many cylinders it adapts to and how easy temporary guest codes are with the keypad. Their complaints are about the motor failing to retract stiff latches, jamming in the cold, fast battery drain with a late warning and recalibration after every battery change.

Frequently Asked Questions

Which is better overall: Nuki Smart Lock Ultra or SwitchBot Lock?

The Nuki Smart Lock Ultra. It has built-in Wi-Fi, Matter over Thread, a rechargeable battery, a two-year warranty and one-time and periodic codes with its keypad. The SwitchBot Lock wins on unlock methods such as NFC and face recognition, and on how many cylinders it fits.

What is the biggest difference between the Nuki Smart Lock Ultra and the SwitchBot Lock?

Connectivity. The Nuki Smart Lock Ultra connects to Wi-Fi by itself and speaks Matter, while the SwitchBot Lock is Bluetooth only and needs a SwitchBot Hub for remote control and for Alexa, Google Home, Apple Home and SmartThings.

Do the Nuki Smart Lock Ultra and the SwitchBot Lock work with Home Assistant?

Yes, both list Home Assistant support. The difference is the other platforms: the Nuki Smart Lock Ultra reaches them directly, and the SwitchBot Lock does so through a SwitchBot Hub.

Does the Nuki Smart Lock Ultra or the SwitchBot Lock have a keypad or fingerprint reader built in?

Neither. Both need a separate keypad for codes and fingerprints. The SwitchBot Lock can also use a Vision Keypad for face recognition and supports NFC tags, which the Nuki Smart Lock Ultra does not.

Who should buy the Nuki Smart Lock Ultra?

Buyers who want a premium, fast retrofit lock with Wi-Fi and Matter built in, Apple Home users, and anyone who prefers a rechargeable battery to swapping cells.

Who should buy the SwitchBot Lock?

Renters and owners with an awkward cylinder, people already using SwitchBot hubs or Home Assistant, and buyers who like NFC tags or a face-recognition keypad, as long as their door latch is not too stiff for its motor.
