Aliro 1.0: What Does the New Unified Access Control Standard Mean for the Smart Home?

A few years after it was first announced in 2023, the Connectivity Standards Alliance (CSA) released its new access control standard, Aliro 1.0, in late February 2026. The Aliro standard aims to standardize the implementation of digital keys across different vendor ecosystems, thereby enabling a single digital key (e.g., Apple Home Key, Google Wallet) to work with all Aliro-enabled smart door locks. This concept is very much like the Matter communication protocol, which aims to resolve fragmentation in the smart home industry.

The Aliro standard is designed to work across three communication technologies, namely 1) Near Field Communication (NFC), 2) Bluetooth® Low Energy (LE), and 3) Ultra-Wideband (UWB). This provides smart home vendors with a flexible range of connectivity options to choose from and enables them to tailor their strategy according to the strengths of each communication mode.

The release of Aliro 1.0 is well-timed, as it coincides with the launch of Matter 1.5 specifications in November 2025, which introduce Matter support for door locks with cameras. The launch of these two specifications is expected to work together to support more innovative use cases and automations for the smart home and has the potential to drive the adoption of smart door locks among consumers.

To be clear, Aliro and Matter fulfill different roles in the smart home. Aliro mainly looks at simplifying home access via the use of standardized digital keys that will work with all certified smart door locks. If implemented with Bluetooth® LE or UWB, the user may not even be required to take out their smartphone due to the longer-range benefits of these wireless technologies. On the other hand, Matter supports automation (e.g., lights turning on automatically when the door lock is opened, etc.) and remote access to these devices. When implemented together, these two technologies have the potential to enable a fully hands-free smart home experience, which may be desirable to certain homeowners.

Another key benefit of Aliro is that it enables a single digital key to work across environments. For example, a user may be able to use a single smartphone or smartwatch to access the home, office, and any other venue (e.g., an educational institution) that has also installed Aliro-compatible access systems.

However, it is important to note that there is currently a wide range of smart door locks that already support hands-free access, with technologies like palm and facial recognition. There is also a wide variety of contact options, such as NFC cards, Personal Identification Numbers (PINs), and fingerprint recognition. Some door locks are also connectivity-enabled (e.g., Wi-Fi), thereby supporting remote access and control. Hence, the immediate question that comes to mind is this: what value does Aliro truly add to the existing smart home ecosystem?

The strongest use case for Aliro may actually go beyond the consumer home. The ease of having a single access method across environments (e.g., schools, office buildings, commercial buildings, hotels, etc.) without the need for multiple physical cards and mobile applications simplifies the overall experience for users. Also, when new entry permissions need to be given and taken away often (like in short-term rentals), Aliro makes these access solutions more secure than just sharing a traditional PIN.

To capitalize on this opportunity, ABI Research recommends that smart home device vendors first understand the potential impact of the Aliro standard on the industry. Thereafter, if Aliro is chosen as a viable strategy, consideration should be given to the appropriate mode of connectivity to use (e.g., NFC, Bluetooth® LE, UWB, or a combination of a few) to help the vendor craft a Unique Value Proposition (UVP) in the access control market.

UWB is emerging as a strong contender for smart-home access technology, building due to its success with digital car keys in the automotive sector. The latest FiRa 4.0 specification release in November 2025 further enhances UWB capabilities by introducing key new features, such as Uplink Time Difference of Arrival (UL-TDoA), Aliro UWB certification, and Suspend Ranging. Some UWB products are already emerging in the market. For example, Aqara, with its Smart Lock U400 solution, has chosen to leverage Aliro-enabled UWB technology for its product strategy. Support from the rest of the smart home ecosystem—e.g., 1) the release of reference designs for interoperable access control solutions using Aliro and Matter by Nordic Semiconductor and 2) interoperability with major solutions like Samsung Digital Home Key and Apple Home Key—is expected to drive adoption of the technology.

On the other hand, Bluetooth® Channel Sounding (CS)—a Bluetooth® feature that supports high-accuracy proximity sensing—is also emerging as an alternative to UWB. While not as precise as UWB, Bluetooth® CS provides other benefits such as reduced power consumption and lower implementation cost due to the existing wider adoption of the technology in smartphones and various Internet of Things (IoT) devices. At CES 2026, Bauer Products introduced its new vehicle lock powered by Bluetooth® CS.

Ultimately, vendors will need to consider how Aliro and the chosen connectivity technology can fit into their overall product strategy roadmap and how NFC, UWB, or Bluetooth® LE technology can be extended to other product lines to form a complete ecosystem, thereby supporting a seamless user experience.
