Google Wallet adds digital home keys for Android smart lock users

Google has begun rolling out digital home keys in Google Wallet, enabling Android users to unlock compatible smart door locks by tapping their phone or approaching the door. The feature arrives years after Apple introduced similar functionality in Apple Wallet in 2021, and Samsung added digital home keys to Galaxy phones earlier this year.

The feature is being released through the Google Home Public Preview program, with broader availability expected in the coming weeks. Users can add a digital key to Google Wallet after setting up a compatible smart lock in Google Home, alongside existing payment cards, car keys, and passes.

Two unlocking methods are available. Near Field Communication (NFC) lets users tap their phone near a compatible smart lock, and the phone does not need to be unlocked if it was unlocked within the previous few hours. Google allows users to enable additional verification for extra security.

The second method uses Ultra-Wideband (UWB) for hands-free unlocking. Called Unlock on Approach, it requires manual activation in Google Wallet and lets compatible smart locks detect the phone and unlock as the user approaches.

Google says NFC-based unlocking works on Android phones running Android 9 or newer, but users also need a Matter-certified smart lock supporting the Aliro standard and a compatible Google Home hub with Thread Border Router functionality. Supported hardware currently includes Aqara U400, Schlage Sense Pro, and Nuki Keypad 2 NFC. For hands-free unlocking, a compatible UWB phone is required, such as Google's Pixel 10 Pro series or newer models. Wear OS smartwatches are not supported at launch.
