A new smart home feature replaces traditional keys with digital access.
MOUNTAIN VIEW, California. Google has introduced digital home keys in Google Wallet, allowing Android users to unlock compatible smart locks by tapping their smartphones against a door or approaching it without physical contact. The feature, launched through Google Home’s Public Preview programme, is expected to reach more users over the coming weeks.
The technology is built around Aliro, an open access standard developed through the Connectivity Standards Alliance. Its purpose is to improve interoperability between smartphones, smart locks and connected home systems, reducing dependence on proprietary access technologies.
Google offers two unlocking methods. Tap to Unlock uses Near Field Communication (NFC), allowing users to open a supported door by placing an Android phone near the lock’s reader. The function works with Android 9 or later and can operate even when the phone’s screen is locked, although additional authentication requirements can be configured.
The second method, Unlock on Approach, uses Ultra-Wideband (UWB) technology to recognize when an authorized smartphone approaches the door. Compatible locks can then unlock automatically without requiring users to touch their devices. This option must be enabled manually and requires both the smartphone and lock to support Aliro UWB.
Google Pixel 10 Pro models and newer compatible devices support the proximity feature, alongside selected Samsung Galaxy smartphones equipped with UWB technology.
The system also changes how household access is managed. Rather than assigning a separate credential to each lock, Google Wallet links a digital key to the home configured in Google Home. A single credential can therefore operate multiple compatible locks, while household members can maintain individual digital keys.
Initial supported products include the Aqara U400, Schlage Sense Pro and Nuki Keypad 2 NFC. Users also need a compatible Google hub supporting Matter and a Thread Border Router, such as the second-generation Nest Hub or Nest Wifi Pro.
Security remains a central consideration. Users can adjust verification settings, manage access permissions and remove digital credentials from Google Wallet. However, the feature’s availability depends on compatible hardware, and Wear OS smartwatches are not supported at launch.
The development reflects a broader shift toward smartphone-based identity and access management. Digital wallets already store payment cards, transportation passes and identification credentials in supported markets. Integrating residential access extends that ecosystem into everyday home security.
For consumers, the immediate benefit is convenience. For smart home manufacturers, the larger opportunity lies in developing interoperable products that can operate across increasingly connected residential environments.
