Google has officially launched digital home key support within the Google Wallet application, marking a significant step for Android users. This new capability allows individuals to open smart locks by tapping their smartphones against the lock mechanism or by simply approaching the door. The feature is currently available in public preview for the Google Home app, with Google stating it will expand to all users over the coming weeks.
The introduction of this feature addresses a long-standing gap in the Android ecosystem. Apple and Samsung users have enjoyed similar digital key conveniences for some time. While the Google Home app previously offered basic unlocking functions, this update integrates Near Field Communication and Ultra-Wideband technologies directly into the Wallet app for broader compatibility with smart hardware.
Users can add digital keys for supported smart locks to their Google Wallet through the Google Home application. A single digital home key can manage multiple locks, streamlining access for various entry points. Additionally, all household members associated with the same Google Home account can add their own unique digital keys to their personal Wallet profiles, ensuring individual access without sharing credentials.
The system offers two primary methods for unlocking doors. The Tap to Unlock feature requires users to hold the back of an NFC-enabled Android phone near the lock reader. This method does not require the phone to be unlocked or for the user to navigate through menus. Alternatively, the Unlock on Approach feature can automatically open the door when the device detects the user walking up to it. However, this hands-free option must be manually enabled within the Google Wallet settings.
The new capabilities are built upon Aliro, an open standard designed to allow any smartphone to unlock any compatible smart lock. Despite this universal goal, the current hardware support is still limited. According to Google, the initial list of supported locks includes the Aqara u400, the Schlage Sense Pro which supports NFC at launch with UWB to follow, and the Nuki Keypad 2 NFC. The company has indicated that more locks will be added to the supported list in the future.
To utilize these features, users need specific hardware requirements. A Matter-enabled Google Hub with a Thread Border Router, such as the second-generation Nest Hub, is necessary for the system to function. For the Tap to Unlock method, an NFC-enabled phone running Android 9 or later is sufficient. The more advanced hands-free unlocking via UWB is restricted to Aliro UWB-compatible Android devices, including the Google Pixel 10 Pro series and newer models.
Smartwatches running the Wear OS operating system are not supported at launch. Google has noted that these devices may be supported in future updates, a prediction that seems likely given that the Apple Watch already offers similar unlocking features. This development suggests that Google is aiming to bring parity with its competitors in the smart home security space.
As the rollout progresses, users should check their device compatibility and ensure their smart locks are on the supported list. The expansion of this feature represents a move toward a more seamless and secure smart home experience for the large Android user base.
The integration of these technologies into Google Wallet highlights the growing importance of digital keys in modern home security. By leveraging existing phone hardware, Google is making it easier for consumers to manage their home access without relying on traditional physical keys or additional fobs.
With the public preview underway, early adopters can begin testing the feature now. Google expects to complete the general availability rollout in the coming weeks, bringing this long-awaited functionality to a wider audience of Android smartphone owners.
