Google Wallet Adds Digital Home Keys for Android Phones

Google Wallet for Android is rolling out digital home keys that let compatible phones unlock supported smart locks with a tap or a wave. The launch includes NFC‑based unlocking for several lock models and UWB‑based "Unlock on Approach" for phones that support Ultra‑Wideband. The feature is initially available through the Google Home public preview and will reach all users in the coming weeks.

How the digital key works

According to 9to5Google, a digital key is added to Google Wallet from the Google Home app. Once saved, the key appears as a simple card with the Google Home logo and the home’s name. When you approach a lock, the phone can either tap the lock’s NFC field or, if both phone and lock support Ultra‑Wideband, open the door as you walk up. The NFC method works even if the phone screen is locked, though you can change the setting to require a screen lock or biometric check.

Which devices and locks are supported

The rollout targets phones running Android 9 or newer. At launch, the feature works on the Pixel 10 Pro series and higher, as well as select UWB‑enabled Samsung Galaxy models. Wear OS watches are not supported at launch. For locks, the initial list includes the Aqara u400 (UWB and NFC), Schlage Sense Pro (NFC now, UWB later), and Nuki Keypad 2 (NFC). More lock models are promised in future updates.

Setting up a digital home key

1. Open the Google Home app and add a compatible smart lock to your home setup.
2. After the lock is configured, the app will prompt you to save a digital key to Google Wallet.
3. Accept the prompt; the key appears in Google Wallet and syncs to any Android phone signed into the same Google account.
4. To adjust verification, open Google Wallet, select the key card, and choose whether unlocking requires the screen lock or biometric authentication.
5. For UWB unlocking, ensure your phone’s UWB feature is enabled in system settings and that the lock is an Aliro‑compatible model.

Security and privacy considerations

The digital key lives in Google Wallet, which is encrypted and protected by the same security measures that safeguard payment cards. By default, NFC unlocking does not require the screen to be unlocked, but you can change that behavior in the app. UWB unlocking only works when the phone is close enough to the lock, reducing the risk of remote attacks. Because the key is linked to the Google Home app rather than a single lock, revoking access to one lock removes it from the shared key, simplifying management for households with multiple doors.

Practical steps for small business owners and nonprofits

• Check device compatibility: Verify that staff phones meet the Android 9 minimum and, if you want UWB unlocking, that they are on the supported Pixel or Samsung list.
• Confirm lock support: Use only the locks listed in the launch (Aqara u400, Schlage Sense Pro, Nuki Keypad 2) or wait for additional models.
• Enable verification: In Google Wallet, set the key to require a screen lock or fingerprint if you prefer an extra layer of protection.
• Sync across accounts: Make sure all authorized users sign into the same Google Wallet account so the key appears automatically on their devices.
• Plan for future updates: Keep the Google Home and Google Wallet apps updated to receive new lock models and security improvements.

If you are already building mobile solutions for your organization, consider how digital keys could simplify access control for office spaces or event venues. For iOS users, we also build iPhone apps; see the examples we have live on the App Store here.

What’s next?

Google says the digital key feature will expand beyond the public preview in the coming weeks, with more lock manufacturers joining the list. As Android phones gain broader UWB support, the "Unlock on Approach" experience may become the default for many users. Keep an eye on updates in the Google Home and Google Wallet apps to stay current.

Overall, the addition of digital home keys to Google Wallet offers a convenient way for Android users to manage door access from the same app they already use for payments and tickets. By following the setup steps and adjusting security settings, small teams can add a modern touch to their everyday security routine without major changes to existing infrastructure.
