Aliro Smart Lock Standard Set for 2026 Release; Samsung Integrates Digital Home Key
The Aliro smart lock standard, which aims to standardize NFC-based tap-to-unlock and Ultrawide Band (UWB) hands-free unlocking, is anticipated to release its initial specification in the first quarter of 2026. Concurrently, Samsung has announced the integration of the Aliro standard into its Samsung Wallet application, introducing a "Digital Home Key" function for compatible smart locks.
Aliro Standard: Paving the Way for Universal Digital Keys
The Aliro standard, an open protocol managed by the Connectivity Standards Alliance (CSA), is designed to enable trusted smartphones and wearables to function as digital keys for smart locks and readers. Announced in 2023, the standard seeks to provide a uniform method for smart locks to communicate with mobile devices, independent of manufacturer or platform.

Nelson Henry, Chair of the Aliro Steering Committee, confirmed the final verification of the protocol. The CSA, also responsible for the Matter standard, anticipates that these foundational developments will facilitate rapid and widespread adoption. The standard aims to extend capabilities similar to Apple's Home Key, which uses NFC for tap-to-unlock and UWB for hands-free unlocking via iPhones, to a broader range of devices including Android phones and other smart home platforms.
Core Communication Protocols and Functionality
Aliro-certified locks are designed to support one or more of the following communication options, offering flexible unlocking methods:
- Near Field Communication (NFC): Facilitates tap-to-unlock functionality by physically tapping a compatible phone or watch against the lock.
- Bluetooth LE (BLE): Allows a phone to initiate an unlock command as a user approaches the door.
- BLE plus Ultrawide Band (UWB): Enables hands-free unlocking when a user with a compatible phone is in proximity to the door, allowing for unlocking without removing the device from a pocket or bag.
It is noted that existing smart lock models may require compatible radios and antennas, potentially limiting upgradeability to Aliro functionality for older devices.
Robust Security and Offline Capabilities
The CSA emphasizes that Aliro's design supports direct and secure communication between a user's device and the lock. This architecture eliminates the need for an accompanying application to be open and does not rely on cloud services. User credentials are stored directly on the device, and communication is secured using asymmetric encryption.
This robust design ensures the system can function seamlessly even when a phone is offline or lacks cellular service.
Industry-Wide Collaboration Fuels Aliro
The development of Aliro is a result of extensive industry-wide collaboration. Key contributors include Apple, Google, Samsung, Allegion, Assa Abloy, Qualcomm, and NXP.
Several prominent lock manufacturers, such as Schlage, Kwikset, X-Things/U-Tec, Level, and Nuki, have already stated plans to support the Aliro standard.
Samsung Wallet Integrates "Digital Home Key"
Samsung is integrating the Aliro standard into its Samsung Wallet application under a new "Digital Home Key" function. This feature will enable users of Galaxy devices to unlock compatible smart locks using NFC and UWB technology. The Digital Home Key expands Samsung's existing Digital Key feature, which was previously exclusive to vehicles, to smart home devices.
For unlocking, NFC functionality requires tapping the door lock, while UWB technology allows for hands-free unlocking by simply approaching the lock with an authorized device. Samsung stated the UWB method is secure.
The feature is scheduled for release in select regions this month, with further expansion planned through new lock releases from various smart lock manufacturers.
Samsung did not specify particular smart lock brands at the time of the announcement.
