TL;DR
Google has added support for Aliro digital home keys in Google Wallet, allowing compatible Android phones to unlock compatible smart locks. The feature is available through the Google Home Public Preview, with a broader rollout expected over the coming weeks. NFC unlocking works on supported phones running Android 9 or later; hands-free unlocking requires UWB support in both the phone and lock.
Google Wallet now supports Aliro digital home keys, letting users add a key for a compatible smart lock and unlock it with an Android phone. Google has made the feature available through the Google Home Public Preview and says it will reach general users over the coming weeks, bringing Android a native digital-key option for locks built on the Aliro standard.

Aliro keys support NFC tap-to-unlock on Android phones running Android 9 or later with NFC. A hands-free approach-to-unlock option is also supported, but only when both the phone and the lock have Ultra Wideband (UWB) hardware and Aliro compatibility. Google lists the Pixel 10 Pro series, including Fold and XL models, and select Samsung Galaxy phones among compatible UWB devices; the source does not name every supported Galaxy model.
To set up a key, a user pairs a compatible lock through the Google Home app, which prompts them to add a digital key to Wallet. The setup also requires a compatible Google hub that acts as a Thread border router, such as a second-generation Nest Hub, Nest Wifi Pro or Google TV Streamer. The report identifies the Aqara Smart Lock U400 as an example of a compatible lock. Google says Wear OS watches are not supported at launch.
The report says users can create one key to operate compatible locks assigned to a single home profile. Other household members added to that Google Home profile can create personal keys, which sync across their signed-in Android phones. The feature is currently limited to the Public Preview; Google’s stated plan is a general release over the coming weeks, rather than immediate availability to every user.
Android Gains a Wallet-Based Door Key
Adding the key to Google Wallet gives Android users a system-level alternative to unlocking a door through an individual lock maker’s app. That may make everyday access simpler for households with supported hardware, while letting users manage a credential alongside other Wallet items. The practical benefit, however, depends on owning a compatible lock, phone and home network setup.
The feature also brings two smart-home standards into the same setup. Aliro handles digital access between a phone and a lock, while Matter addresses broader smart-home interoperability. The standards are separate, but Google’s requirement for a Matter-capable hub and Thread connectivity means setting up an Aliro key also involves Google Home and compatible smart-home infrastructure. That is relevant for buyers weighing the full cost and compatibility of a lock, not just its unlocking method.

Aliro, Matter and Google Home Setup
Aliro is a digital-access standard developed by the Connectivity Standards Alliance, the organization behind Matter. It is designed to provide a common way for a phone’s digital credential and a lock’s reader to communicate, using technologies including NFC, Bluetooth Low Energy and UWB. Matter is a separate protocol for connecting smart-home devices; the two standards serve different functions even when devices use related network hardware.
Before this Wallet support, Android users often relied on a lock manufacturer’s app for phone-based access, according to the source report. Google’s approach follows digital-key offerings from Apple and Samsung, although the details and compatibility requirements differ across platforms. The report says Google’s Aliro setup does not appear to require an extra approval step to enable its express NFC and UWB unlocking experience. That description is based on the reported launch details, not a full comparison of every platform or lock.
“The feature will roll out to all general users over the coming weeks.”

Compatibility and Rollout Details
Exact availability remains limited: the feature is in Public Preview, and the source does not give a specific date for the general release. It also does not provide a complete list of compatible smart locks or Samsung phones. Buyers should check Google’s current device and lock compatibility information before relying on a particular model.
The report does not specify whether availability varies by country, whether all listed hubs work with every compatible lock, or how digital keys behave if a phone is lost, replaced or disconnected from a Google Home profile. It also does not give detailed security or recovery procedures. Those points are not established by the launch information provided.
Broader Release and Device Support
Google says the feature is due to reach general users over the coming weeks. Until then, interested users can join the Google Home Public Preview through the app’s settings, provided they have supported hardware and the required home network setup.
Further rollout details to watch include a firm public-release date, a fuller list of Aliro locks and supported phones, and any change to the initial Wear OS limitation. Until Google publishes those details, compatibility should be checked for each phone, lock and hub combination rather than assumed from support for Aliro alone.
Key Questions
What is Google adding to Wallet?
Google Wallet can store an Aliro digital home key for a compatible smart lock, letting a supported Android phone unlock the door.
Which Android phones can use the key?
For NFC tap-to-unlock, the source says a phone needs Android 9 or later and NFC. Hands-free unlocking additionally requires UWB in both the phone and the lock. Google lists Pixel 10 Pro series models and select Samsung Galaxy phones as compatible UWB devices, but the report does not name every supported model.
Does the feature work with every smart lock?
No. The lock must support the Aliro standard, and setup also requires a compatible Google hub and Thread network. The report names the Aqara Smart Lock U400 as one example.
Can a Wear OS watch unlock the door?
Not at launch. The source report says Google’s initial Aliro home-key feature does not support Wear OS smartwatches.
When will the feature be available to everyone?
It is available through the Google Home Public Preview. Google says a general rollout is expected over the coming weeks but has not provided a specific date in the source material.
