Aliro Standard Emerges to Unify Smart Locks
A new standard called Aliro is gaining traction to solve smart lock interoperability. The goal is to let digital credentials in Apple Wallet, Google Wallet, and Samsung Wallet work seamlessly with any compliant lock, creating a universal standard for digital keys.
The Connectivity Standards Alliance (CSA), the same body that developed the Matter smart home protocol, officially launched the Aliro 1.0 specification in February 2026. This new standard aims to eliminate the fragmentation in the access control industry, where proprietary systems have historically locked users into single-vendor ecosystems. Aliro operates as a point-to-point communication protocol, meaning it works directly between a user's device (like a smartphone or wearable) and the lock, without needing a Wi-Fi network or hub. This allows for secure, offline access, which is particularly useful in areas with poor connectivity such as underground garages. The standard leverages a combination of wireless technologies to support different use cases. It uses NFC for simple tap-to-unlock functionality, Bluetooth Low Energy (BLE) for user-initiated long-range communication, and Ultra-Wideband (UWB) for secure, hands-free unlocking that can precisely determine if the user is directly in front of the door. Security is a core component, with Aliro employing asymmetric cryptography to establish a secure and private interaction between the device and the lock. The private key is stored securely on the user's device and is never exposed, similar to how contactless payments are secured. While both are managed by the CSA, Aliro and Matter serve distinct functions. Matter focuses on the administration and control of smart home devices over an IP network (e.g., "Is the door locked?"), whereas Aliro handles the direct access authorization ("Is this person allowed in?"). Future smart locks will likely feature both logos, indicating comprehensive smart home integration and universal access compatibility. Major mobile wallet providers, including Apple, Google, and Samsung, have committed to supporting Aliro, enabling a standardized digital key experience within the native wallet apps people use daily. This broad support is designed to accelerate adoption and move beyond just residential front doors to corporate offices, hotels, and universities. The first wave of companies expected to achieve Aliro 1.0 certification includes major lock manufacturers like Allegion, Aqara, Kwikset, and Nuki Home Solutions, alongside key silicon vendors such as Nordic Semiconductor, NXP, and STMicroelectronics. Products supporting the standard are anticipated to become available later in 2026.
