Google has officially introduced digital home key support to Google Wallet, enabling Android users to open compatible smart locks by either tapping their smartphone against the reader or simply walking up to the door. The functionality is currently rolling out in public preview within the Google Home app and is scheduled to reach all users globally over the coming weeks. This integration brings Android devices up to speed with competing ecosystems like Apple and Samsung, which have offered comparable smartphone-based door unlocking conveniences for quite some time now. By leveraging Near Field Communication and Ultra-Wideband technology built straight into modern mobile hardware, users can now manage multiple household locks through a single digital key stored directly inside their personal Google Wallet.
The deployment allows every single household member linked to the exact same Google Home account to generate and add their own independent key to their personal mobile device. While Google Home previously offered limited unlocking features, this new update taps directly into advanced device radios for a seamless entry experience. Multiple locks can be organized and controlled effortlessly from the mobile app. However, users must navigate specific hardware prerequisites to take advantage of these new capabilities across their smart home setups.
Key takeaways
- Google Wallet now supports digital home keys for compatible Android smart locks.
- The feature utilizes NFC and UWB technology for Tap to Unlock and Unlock on Approach.
- Compatible locks at launch include the Aqara u400, Schlage Sense Pro, and Nuki Keypad 2 NFC.
- A Matter-enabled Google Hub with a Thread Border Router is required for the system.
Unlocking methods and hardware requirements
The system supports two distinct modes of entry to accommodate different user preferences. Tap to Unlock requires holding the rear of an NFC-enabled Android phone near the lock reader, and it functions conveniently even when the phone remains locked without requiring the user to wake the screen. Meanwhile, Unlock on Approach offers a hands-free experience by automatically opening the door upon detecting an approaching user, though this specific setting must be manually activated within Google Wallet by the owner.
Hands-free unlocking relies strictly on Aliro Ultra-Wideband-compatible Android phones, such as the Google Pixel 10 Pro series and newer devices. The underlying system architecture is built upon Aliro, which serves as an open standard engineered to allow any smartphone to interact seamlessly with any smart lock. However, hardware compatibility remains restricted during the initial launch window. Tap to unlock itself requires NFC-enabled phones running Android 9 or later software updates.
Supported devices and ecosystem outlook
At present, the roster of compatible smart hardware remains relatively brief as manufacturers adopt the new standard. Google's official announcement confirms that initial supported locks include the Aqara u400, the Schlage Sense Pro, and the Nuki Keypad 2 NFC. For the Schlage lock, NFC support is available at launch while Ultra-Wideband functionality will follow in a subsequent update, with additional lock models promised down the line by Google.
Beyond having a compatible smartphone and smart lock, utilizing these advanced features requires a Matter-enabled Google Hub equipped with a Thread Border Router, such as the second-generation Nest Hub. Wear OS smartwatches are completely unsupported at launch, according to Google's statements, though future updates could potentially bridge that gap, mirroring similar capabilities already found on Apple Watch platforms.
