TL;DR
Google Home Public Preview now lets Android users create Aliro digital home keys and add them to Google Wallet for compatible smart locks. NFC tap-to-unlock is supported on qualifying Android phones; hands-free unlocking requires UWB support in both the phone and lock. Google says a wider rollout is planned over the coming weeks.
Google has added Aliro digital home key support to Google Wallet through the Google Home app Public Preview, allowing Android users to store credentials for compatible smart locks and unlock doors using NFC or, with supported hardware, hands-free UWB. Google says the feature is expected to reach general users over the coming weeks; the launch does not support Wear OS watches.

To set up a key, users pair an eligible lock with the Google Home app, which then prompts them to create a digital key and add it to Wallet. The report says one key can operate compatible locks assigned to the same home profile. Other household members can create personal keys through their Google Home profiles, with keys syncing across their signed-in Android phones.
NFC tap-to-unlock requires an Android phone running Android 9 or later with NFC. Hands-free access as a user approaches the door requires UWB support in both the phone and lock, as well as Aliro compatibility. Google lists the Pixel 10 Pro series, including Fold and XL models, and select Samsung Galaxy phones among devices with compatible UWB hardware. The source does not name every supported phone or provide a complete compatibility list.
The setup also requires a Google hub with Thread border-router capability, according to the report. Examples include the second-generation Nest Hub, Nest Wifi Pro and Google TV Streamer. Google Home Public Preview is the current route to the feature; Google says general availability is planned over the coming weeks. Wear OS watches are not supported at launch.
Android Keys Move Into Wallet
Adding home keys to Google Wallet gives Android users a built-in option for storing and using access credentials, rather than relying only on a lock maker’s own app. The change could make digital entry more consistent for households with compatible locks, particularly when residents already use Google Home and Wallet. The practical benefit depends on the phone, lock and home-network equipment each household has.
The release also brings Google into a growing effort to make digital keys work across device and lock makers. Aliro is intended to standardize communication between a phone’s digital key and a lock’s reader. That may reduce ecosystem-specific barriers, but this rollout alone does not establish how many products will support the standard or whether users will have the same experience across manufacturers.

How Aliro Fits With Matter
Aliro is a digital access standard developed by the Connectivity Standards Alliance, the organization that also develops Matter. The standards have distinct roles: Aliro handles the credential and communication used to unlock a door, while Matter supports interoperability among smart-home devices. The source describes Aliro as using NFC, Bluetooth Low Energy and UWB, depending on the access method and hardware.
Aliro and Matter are separate protocols, not interchangeable standards. The reported Google setup pairs the lock through Google Home and requires a compatible hub and Thread network, which can also form part of a Matter-based smart home. That requirement may encourage users to build out connected-home infrastructure, but it does not mean Aliro itself is Matter.
The report identifies the Aqara Smart Lock U400 as an example of a compatible Aliro lock. It does not establish that every Matter lock, or every smart lock that works with Google Home, can create a Google Wallet key. Compatibility with Aliro is a separate requirement.
“The feature will roll out to all general users over the coming weeks.”

Compatibility Still Has Limits
The full list of supported Aliro locks and Android phones is not provided in the source material. It is also unclear which select Samsung Galaxy models qualify for UWB unlocking, or whether additional devices will be added before the general rollout. Users should not assume that NFC support on a phone or Google Home compatibility for a lock is enough on its own.
The source does not give a firm date for general availability, detail how access credentials can be revoked or recovered, or describe how the feature behaves when a phone has no battery or a home network is unavailable. Those questions may be answered in product documentation or through wider availability. At launch, the report says Google Wallet keys cannot be used from Wear OS watches.
Broader Rollout And Device Lists
Google says it plans to extend the feature from Google Home Public Preview to general users over the coming weeks. Interested users can join the preview through the Google Home app’s settings, according to the report. Google’s broader rollout and updated support information should clarify which phones and locks can create Wallet keys.
For now, users considering the feature need to check support across the full setup: an Aliro-compatible lock, a qualifying Android phone, and a suitable Google hub and Thread network. UWB hands-free unlocking requires compatible UWB hardware on both the phone and lock; otherwise, NFC tap access may be available if the phone meets the stated Android and NFC requirements.
Key Questions
How do Android users add a home key to Google Wallet?
Pair an Aliro-compatible lock with the Google Home app. The app should prompt eligible users to create a digital key and add it to Wallet. The feature is currently available through Google Home Public Preview.
Which Android phones can use the digital key?
NFC tap access requires Android 9 or later and NFC. The source lists Pixel 10 Pro series models, including Fold and XL, and select Samsung Galaxy phones for UWB support, but does not identify every qualifying model. Hands-free unlocking also requires a UWB-capable lock.
Does every Google Home-compatible smart lock work?
No. The lock must support the Aliro standard to use an Aliro key in Google Wallet. Google Home compatibility by itself does not establish that a lock can create a Wallet key.
Can a Wear OS watch unlock the door at launch?
No. The report says Wear OS watches are not supported at launch. Google has not provided a smartwatch support date in the source material.
When will the feature be available to everyone?
Google says a general rollout is expected over the coming weeks. A specific release date is not given; the current option is the Google Home app Public Preview.
