Google has expanded the functionality of its Google Wallet app by adding support for digital home keys. The update allows Android users to store keys for compatible smart locks directly within the Wallet interface. This move brings the platform closer to parity with competitors, as Samsung and Apple users have already enjoyed similar convenience for some time.
Tap and Approach Unlocking Methods
The new feature operates through two distinct methods depending on the hardware capabilities of the user’s device. The first method, described as tap to unlock, utilizes Near Field Communication (NFC). Users simply hold the back of an NFC-enabled Android phone near the lock reader. This action does not require the phone screen to be unlocked, streamlining the process for quick entry.
The second method is unlock on approach, which relies on Ultra-Wideband (UWB) technology. This hands-free option must be manually enabled in the Google Wallet settings. Once active, the system detects when a user is walking toward the door and automatically unlocks it. This feature requires specific hardware support to function correctly.
Hardware and Compatibility Requirements
Google states that the feature is currently available in public preview for the Google Home app and will roll out to all users over the coming weeks. The underlying technology is built on Aliro, an open standard designed to ensure interoperability between different smartphone and lock manufacturers. However, the list of supported hardware remains limited at launch.
Compatible smart locks currently include the Aqara u400, the Schlage Sense Pro, and the Nuki Keypad 2 NFC. Google noted that the Schlage Sense Pro supports NFC at launch, with UWB capabilities to follow in a future update. Users also need a Matter-enabled Google Hub with a Thread Border Router, such as the second-generation Nest Hub, to facilitate the connection.
On the phone side, tap to unlock requires an NFC-enabled device running Android 9 or later. Hands-free unlocking is restricted to Aliro UWB-compatible phones, which currently includes the Google Pixel 10 Pro series and newer models. Multiple locks can be managed through a single digital home key within the app. All household members linked to the same Google Home account can add their own keys to their personal Wallets.
Wear OS smartwatches are not supported at launch. Google indicated that watch support may arrive in the future, a likely development given that Apple Watch already offers similar features. The company did not provide a specific timeline for when Android wearables will gain access to the digital home key functionality.
