Samsung Wallet introduces digital home key for Smart Door Locks

Samsung has introduced a new Digital Home Key feature in Samsung Wallet that allows Samsung Galaxy users to unlock compatible smart door locks using their smartphones.

The feature started rolling out in select regions in March 2026. It expands Samsung Wallet’s digital key system, which was previously used mainly for cars, to now include home door locks.

With Digital Home Key, users can unlock their doors using their Galaxy phone once the smart lock is set up through Samsung SmartThings and supports the Matter smart home standard. After setup, the digital key can be added to Samsung Wallet during the lock’s onboarding process.

Depending on the device and lock, users can unlock their door in several ways. They can tap their phone using near-field communication (NFC), unlock automatically when the phone is nearby using ultra-wideband (UWB), or control the lock remotely through the app.

The feature is built on Aliro, a smart lock communication standard developed by the Connectivity Standards Alliance. Samsung said this helps ensure that digital keys work across different brands and devices.

Several smart lock brands are working with Samsung to support the feature, including Aqara, Nuki, Schlage, and Xthings.

Samsung said the digital keys are stored securely inside Samsung Wallet and protected by Samsung Knox, the company’s security platform. Users can also remove access remotely through Samsung Find if the phone is lost. Biometric or PIN authentication is also required to manage or use the digital keys.

Samsung said support for the feature will expand as more compatible smart locks become available.
