For those in the Apple Home ecosystem, the Nuki Smart Lock paired with the Keypad 2 NFC offers a compelling retrofit option that finally brings full Apple Home Key support without replacing your door’s external hardware. Designed to bolt onto the interior side of your deadbolt, the Smart Lock leaves the outside untouched, while the Keypad 2 NFC—mounted outside—serves as the NFC surface enabling digital key access.

Design, installation, and how it works
Installation is simple: the Smart Lock fits inside, connected to your existing deadbolt’s mechanism, and includes a rechargeable internal battery that charges via a USB-C cable with a magnetic connector. The Keypad 2 NFC runs on two AAA batteries, offering roughly a year of life. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/)) The keypad can be mounted using screws or adhesive and accepts multiple unlocking methods: NFC Home Key from Apple or supported digital wallets, passcodes, and fingerprints.

Integration & features
One of the standout features is support for Home Key via the Aliro standard, which lets you tap to unlock using an iPhone or Apple Watch, as well as digital keys like Samsung’s wallet options or NFC-enabled devices in Nuki’s app mode. ([macrumors.com](https://www.macrumors.com/review/nuki-keypad-2-nfc/?utm_source=openai)) Matter synergy is built in, too, though getting Home Key working may require compatible hub devices. ([macrumors.com](https://www.macrumors.com/review/nuki-keypad-2-nfc/?utm_source=openai))
Security is taken seriously: all unlocking methods—from tap to fingerprint to code—use end-to-end encryption, with access data stored locally unless you opt into cloud services. The keypad is IP54 rated, protecting against dust and splashes, making it suitable for outdoor placement under light exposure.

What works, what doesn’t
The bundle delivers mostly smooth experience. Apple Home integration is good; Home Key and Matter unlock work well once set up. The charging process for the Smart Lock is praised. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/)) Things to note: the keypad tip-up designs can sometimes confuse guests who expect a traditional doorknob motion when unlocking. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/)) Also, while there is a variety of features, the setup is not always seamless—Matter-based networking and Home Key pairing sometimes require trial and error. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/)) Finally, there is no Ultra Wideband support, a feature some competitors are pushing as the next step.

Value & pricing
At press time, the bundled Smart Lock + Keypad 2 NFC sells for around US$289, marked down from $378. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/)) Buying the Keypad 2 NFC separately comes in at approximately $179, while the Smart Lock alone is priced near $199.

Overall, this combo earns a rating of 4.5 out of 5. The score reflects the strong feature set, Apple Home Key compatibility, and thoughtful design. Its drawbacks—design quirks, price tag, setup complexity—drag the score slightly. ([appleinsider.com](https://appleinsider.com/articles/26/08/25/nuki-smart-lock-keypad-2-nfc-review-a-low-profile-lock-with-apple-home-key-support/))
For renters or homeowners who want advanced smart-lock features without replacing their external hardware, this Nuki setup delivers some of the most flexible, future-proof unlocking options available right now. It’s especially useful for Apple Home users who want to simplify access with Apple Wallet or Wearables.
What this means for the market: digital key standards like Aliro plus NFC tools will become table stakes for smart locks. If competitors want to stay relevant, they’ll need to deliver similar NFC/Home Key convenience or risk losing to retrofit solutions like Nuki that hit that sweet spot.
