Samsung Wallet Expands to Unlock Your Home with Digital Home Key

Samsung Wallet is gaining a significant new capability: the ability to unlock compatible smart door locks. Announced at Mobile World Congress 2026, the Digital Home Key feature, powered by the Aliro standard, extends Samsung Wallet’s functionality beyond mobile payments, IDs, and vehicle access to now include access to your home.

What is Digital Home Key?

Digital Home Key allows Samsung Galaxy users to use their smartphone to unlock compatible smart locks. This feature builds upon the Aliro protocol, a standardized communication method for smart locks developed by the Connectivity Standards Alliance (CSA). The integration aims to provide a secure and convenient way to manage home access within the existing Samsung Galaxy ecosystem. According to Woncheol Chai, EVP and Head of Digital Wallet Team at Samsung Electronics, the expansion reflects Samsung’s commitment to delivering “trusted mobile experiences” Samsung Newsroom.

How Does it Work?

To use Digital Home Key, users first need to set up a compatible smart lock through the Samsung SmartThings app using the Matter smart home standard. Once connected, the Digital Home Key can be added to Samsung Wallet as part of the lock’s onboarding process. Unlocking methods vary depending on the smartphone model and the smart lock’s capabilities:

• NFC: Most users will be able to unlock their door by tapping their smartphone using Near Field Communication (NFC) technology.
• UWB: Select devices will support hands-free access using Ultra-Wideband (UWB) proximity detection, starting in April 2026.
• Remote Access: Users can also manage the lock remotely through the Samsung Wallet app.

Security and Compatibility

Samsung emphasizes the security of Digital Home Key, stating it is “designed to align with EAL6+ grade certification standards” Neowin. The feature leverages Samsung Knox, the company’s security platform, to protect digital keys. If a device is lost, users can remotely manage or remove access through the Samsung Identify service. Authentication within Samsung Wallet requires a biometric scan or PIN.

Digital Home Key is currently compatible with smart lock brands including Aqara, Nuki, Schlage, and Xthings (Ultraloq) Android Headlines.

The Aliro Standard and the Future of Digital Keys

The Aliro standard, unveiled in late 2023 by the Connectivity Standards Alliance (CSA), aims to address fragmentation in the digital key market. Previously, users often needed separate apps for different smart lock brands. Aliro establishes a universal communication language between the lock and the mobile device, using technologies like Bluetooth Low Energy for initial connection Neowin.
