Why Aliro could render current smart locks obsolete

Connected locks promise an easy life: hands-free access, remote invitations, opening audits… But so far, reality often disappoints. A multitude of applications, incompatibility of badges and remotes, brand fragmentation: the user juggles between incompatible ecosystems and applications differentiated by location. In this cluttered landscape, the announcement of Aliro has made a shocking impact on the home automation sector. Born from an unprecedented collaborative effort orchestrated by the Connectivity Standards Alliance (CSA), this new standard enjoys significant support from Apple, Google, and Samsung. Its goal? To create a universal, secure, and easy-to-integrate protocol, so that every smartphone or smartwatch becomes a universal digital key, capable of opening any compatible lock, regardless of the manufacturer.

Today, a family staying in different hotels or frequently changing offices has to install several applications, synchronize multiple different badges, and sometimes even request complex technical supports in case of failure or device change. The proposal of Aliro is based on unprecedented interoperability: a communication standard between mobile devices and electronic locks, which would rely on integration within the native digital wallets of each manufacturer, and uncompromising security thanks to asymmetric cryptography. It rethinks the usage of smart access, both for individual housing and for luxury hotels, innovative companies, or cutting-edge university campuses… But the road to mass adoption is not without challenges. An overview of the strengths, obstacles, and potential transformers of Aliro in the connected lock of the future.

Aliro: transforming connected locks through revolutionary interoperability

Access control in the realm of home automation has become considerably more complex over time with innovations. Users are faced with a multiplication of solutions, each brand promoting its own application and technology without concern for unification. The result: a cluttered portfolio of applications, numerous physical badges, and a fragmented user experience.

This fragmentation penalizes both efficiency and security: less fluidity in door openings, the risk of forgetting the necessary application or compatible badge, and difficulties in transferring access rights during device or owner changes. Building or hotel managers must juggle incompatible systems, complicating maintenance and training.

The stakes are therefore twofold: simplify the user’s life while ensuring security and flexibility for operators and owners. Aliro disrupts this precarious balance by aiming to become the equivalent of the Matter standard for physical access – uniting brands, platforms, and building types under a single banner.

Aliro: a standard protocol supported by Apple, Google, and Samsung

Aliro is neither a product nor a lock as such. It is a standard protocol for secure communication, the result of the work of the Connectivity Standards Alliance (CSA), which is already behind Matter. Three tech giants – Apple, Google, and Samsung – play a driving role, ensuring native integration of Aliro into the systems of smartphones, tablets, and connected watches.

The objective is to offer a single channel for the secure exchange of access information between mobile devices and connected locks, so that users do not have to download a different application every time. A new standard based on openness, ease of use, and enhanced security. Renowned manufacturers like Nuki are already expected to soon deploy the first compatible locks.

Key benefits of the Aliro protocol for a simplified connected lock experience

The main argument for Aliro lies in the total interoperability between devices. By leveraging a recognized and open standard, each player maintains its specificity while ensuring universal compatibility for the end user. No more juggling between physical badges or installing yet another application: the key is already in the digital wallet of the smartphone, like transport tickets or digital bank cards.

List of major benefits :

• Extreme simplification of the user experience: a single access point for all compatible locations.
• Enhanced security: asymmetric cryptography ensures superior protection against copying and hacking of accesses, far surpassing the resistance of traditional badges.
• Great flexibility for assigning or revoking access rights, possible remotely and in real-time.

In addition, there is the prospect of significantly reducing the number of applications to manage and the possibility of a smooth migration from existing access control systems.

Innovative technologies of Aliro for a secure and efficient connected lock

NFC, Bluetooth Low Energy, and Ultra-Wideband: the technical pillars of Aliro

The Aliro standard relies on three key technologies: NFC (Near Field Communication), Bluetooth LE (Low Energy), and Ultra-Wideband. Each plays a complementary role in ensuring flexibility and security.

NFC allows unlocking through simple close contact, reassuring for users who prefer to have control over the opening process. Bluetooth offers the ability to access the door from a certain distance while limiting energy consumption. Finally, Ultra-Wideband enables innovative experiences, such as “hands-free” unlocking with centimeter precision, ideal for private parking or access for people with reduced mobility.

These technologies, already present on most modern smartphones, accelerate the adoption and compatibility of the protocol.

Offline operation: a major asset for closed environments

Unlike many connected systems, Aliro does not necessarily depend on an internet connection. Communication occurs between the mobile terminal and the lock via NFC, Bluetooth, or Ultra-Wideband, in a completely local mode. This choice is crucial for settings where the connection is unstable or absent: underground parking lots, sensitive sites, or isolated regions.

This offline mode significantly reduces the risks associated with network outages, while limiting exposure to remote cyber attacks. The user therefore retains reliable access regardless of internet coverage quality.

Advanced cryptography to protect against digital key hacking

Security is at the heart of Aliro’s specifications. The protocol relies on asymmetric cryptography, considered one of the most advanced standards for thwarting hacking or cloning attempts. Exchanges between the smartphone and the lock are protected by a public-private key: only the person with the private key (stored securely on the device) can authenticate the opening. This architecture makes forgery or copying nearly impossible, where older badges remained vulnerable.

In the event of theft or loss of the device, instant deactivation of the digital key via the digital wallet enhances user responsiveness and peace of mind.

Use cases and applications of Aliro in modern connected locks

Residential and tertiary deployment: Aliro in homes, hotels, and university campuses

The ambition of Aliro is reflected in the plurality of its applications. At home, families secure access without worrying about relaying between babysitters, delivery persons, or visiting friends – a simple digital invitation is enough. In hospitality, creating a temporary key for a client becomes as simple as sending a text message. On a university campus, students and teachers only need their smartphone or watch to access various buildings.

This versatility is both appealing and reassuring, allowing for the unification of access management in historically fragmented environments.

The flexibility of Aliro for varying sizes and types of secured environments

Aliro adapts to all scenarios: collective buildings, multi-tenant offices, hotels, coworking spaces, or secured laboratories. Its flexible management of access rights (creation, modification, revocation in real-time) appeals to managers, whereas its ease of use favors adoption by occupants.

Beyond the technical aspect, the Aliro standard allows for innovative scenarios: for example, the temporary sharing of a digital key during an event, or generating access rights for maintenance staff without resorting to a perishable badge.

One protocol for all secured scenarios: this is the strong promise, resonating with the success of Matter in the unification of connected objects.

Barriers to the adoption of Aliro: compatibility, industrial integration, and required hardware

The enthusiasm generated by Aliro should not obscure the very real challenges. From a hardware perspective, most existing connected locks would not be compatible without a replacement or hardware upgrade: NFC and Ultra-Wideband are not universally present. Manufacturers thus find themselves facing an integration phase that, as seen with the deployment of Matter, can prove lengthy and sometimes chaotic.

Another obstacle: the necessity of following the CSA certification program, ensuring interoperability and security, but also, potentially, commercial slowdowns for some manufacturers. Finally, it remains to convince users to migrate, as some remain attached to the traditional physical key or badge. The precedent of Matter nonetheless shows that a collective dynamic, led by Apple, Google, and Samsung, can transform a sector on a large scale.

Future perspective for Aliro: user impact and evolution in the home automation ecosystem

Expected benefits: universal key on smartphone and simplification of home automation applications

By integrating directly into the core of smartphone operating systems, Aliro aims to make the phone or watch the universal key of tomorrow. Gone are the multiple apps, proprietary systems: thanks to the support of Apple, Google, and Samsung, access management becomes native, responsive, and centralized.

A key benefit for home automation: each life scenario becomes easier – the user can activate an arrival scenario (heating, lighting, alarm) at the same time as opening, enhancing everyday automation.

• Reduction in the number of applications and fluidity between different environments: the standard promises unprecedented portability of access rights, regardless of context or lock brand.
• Improved security through a standard and encrypted protocol: protection against cloning, centralized management of rights, and increased traceability of accesses.

Critiques and limitations to consider: technological dependence and physical backup solutions

Any technological advance raises questions. What happens in case of loss, theft, or malfunction of the smartphone? Critics of digital exclusivity remind us that access should not solely depend on the phone’s battery. That’s why physical access solutions remain essential, even in case of sudden failure.

Users also question practicality: the increasing size of mobile devices and the sometimes precarious battery life raise real usage concerns in certain contexts (elderly individuals, children, cleaning staff not always using the latest technologies).

Roadmap and perspectives: launch, certifications, and future integration of Aliro

The CSA published version 1.0 of the Aliro specification in the spring, opening the certification program to willing manufacturers. Nuki has already communicated about its first compatible models (notably through its upcoming keypad very soon), and other access control giants are expected to follow by the end of the year. Exploration of new usages (like temporary secure sharing of access), strengthening interaction with Matter, and likely evolution toward new scenarios (parking access, parental control…) are already anticipated.

The challenge is not only technical but also societal: successfully transitioning to a dematerialized society where trust, simplicity, and security intertwine at all doors. Aliro thus appears as a quiet revolution, to be closely followed by all players in modern home automation.
