# Nuki Smart Lock (Deadbolt)

Nuki Smart Lock (Deadbolt) is the direct-Matter Nuki model for North American single-cylinder deadbolts. It is appealing if you want Nuki's inside-only retrofit approach, but the deadbolt fit and Thread coverage have to be right.

## Ecosystem Support

- Apple Home: Supported
- Google Home: Supported
- Alexa: Supported
- SmartThings: Supported
- Home Assistant: Supported

## Best For

- U.S. and Canadian buyers with compatible single-cylinder deadbolts
- Homes that want an inside-only retrofit instead of a full exterior lock replacement
- Matter users who can also keep Nuki's app for lock management

## Skip If

- Your door uses a multipoint lock, mortise lock, or incompatible deadbolt
- You want a full keypad deadbolt replacement
- You do not have a Matter hub with Thread support for the Matter path

## Setup Notes

- Use Nuki's U.S. compatibility check for the single-cylinder deadbolt before buying.
- Install and charge the lock through the Nuki app before pairing to Matter.
- Use Matter over Thread for ecosystem control, and use Nuki's app for remote access, logs, and detailed permissions.

## Known Limitations

- This North American model is separate from Nuki's Euro profile, Swiss round, and Nordic cylinder products.
- Door alignment and deadbolt movement matter because the motor turns existing hardware.
- Matter lock support can vary for access users, codes, logs, and notifications.

## Pros

- Nuki's North American direct-Matter deadbolt retrofit
- Installs over an existing single-cylinder deadbolt on the inside of the door
- Supports built-in Wi-Fi for Nuki app remote features plus Matter for ecosystem control
- Works with Keypad 2 and Keypad 2 NFC bundles

## Cons

- Only fits compatible single-cylinder deadbolt doors
- Matter use still requires a compatible hub and Thread border router
- Nuki app features and Matter ecosystem features are not the same surface

## Nuki's North American lock is a different product

The North American Nuki Smart Lock is not the Euro profile Nuki lock with a different plug in the box. It is a deadbolt retrofit designed to sit on the inside of compatible single-cylinder deadbolt doors.

That makes it a cleaner comparison to Kwikset, Schlage, and Aqara deadbolt options than to Nuki's European cylinder models. The outside of the door can stay familiar, but the existing deadbolt has to move smoothly.

## Wi-Fi for Nuki, Thread for Matter

Nuki describes the deadbolt model as having built-in Wi-Fi for the Nuki app path and Matter integration for smart-home control. For Matter, plan on a compatible hub and Thread support.

That split is important. Nuki can remain the place for remote access, activity logs, permissions, charging details, and accessory setup. Matter is the route into Apple Home, Google Home, Alexa, SmartThings, Home Assistant, or another Matter controller.

## Who should skip it

Skip it if your door is not a compatible single-cylinder deadbolt or if you want a full exterior keypad deadbolt. The Nuki approach is strongest when the existing outside hardware should stay and the inside thumb turn can be motorized without fighting the door.
