What's New

The era of choosing a smart lock based on which ecosystem it belongs to may soon be over. A quiet revolution is unfolding in the smart lock industry, driven by an open standard called Matter — and it promises to make devices from different brands finally speak the same language.

At CES 2026 in January, multiple manufacturers unveiled new-generation smart locks sporting built-in Matter support, signalling that the connectivity standard has decisively moved from concept to mass-market reality. For consumers, this means a future where a single smart lock can work seamlessly with Apple Home, Google Home or Amazon Alexa — no ecosystem loyalty required.

Breaking down the walls

The smart lock sector has long been plagued by fragmentation: a lock from brand A might only work with platform B, leaving consumers locked into costly ecosystems with little interoperability. Matter, launched in 2021 by the Connectivity Standards Alliance (CSA), is an application-layer protocol designed specifically to demolish these proprietary barriers and establish a unified language for smart home devices.

More than 550 technology companies have now joined the alliance. Apple, Amazon and Google have all committed to making their voice assistants and smart home ecosystems fully compatible with Matter-certified devices. In the smart lock category, the protocol supports core functions including remote locking and unlocking, user configuration, and integration with broader smart home systems — enabling cross-ecosystem automation between locks, smart speakers and mobile apps from different manufacturers.

Market figures underscore the scale of the opportunity. According to Global Industry Analysts Inc (GII), the worldwide smart lock market reached $3.23 billion in 2025 and is projected to climb to $3.72 billion in 2026, on track to hit $7.52 billion by 2031 — a compound annual growth rate of 15.11%. China's market is expanding even faster, with nationwide smart lock sales reaching 17.81 million units in 2025 and market value estimated to exceed 40 billion yuan.

CES 2026 showcases a maturing market

The Las Vegas trade show saw a flurry of Matter-enabled smart locks announced, with price points dropping to levels that could accelerate mainstream adoption.

Kwikset unveiled the Aura Reach Matter smart lock at $189, supporting Matter-over-Thread and offering compatibility with Amazon Alexa, Google Home and Apple Home — positioning it as one of the more accessible Matter locks on the market. Chinese electronics giant TCL introduced two models — the D2 Pro Palm Vein smart lock and the D2L fingerprint lever lock — both featuring Matter-over-Thread with battery life of up to eight months, slated for release in the second quarter of 2026.

Lockly's Affirm series brought native Matter compatibility with NFC, PIN code and app-based remote access, priced at $179.99 and due by late Q2 2026. Meanwhile, U-tec announced what it describes as the industry's first smart lock combining biometric recognition with native Matter-over-Thread: the Ultraloq Bolt Fingerprint Matter, offering six unlocking methods including fingerprint, mobile app and keypad.

Two standards, one seamless experience

A related development is the emergence of Aliro, a complementary standard focused on creating a unified specification for digital keys. Released in March 2026, the Aliro specification works alongside Matter-enabled locks for near-field communication unlocking. Nordic Semiconductor has already published a reference design supporting both Aliro and Matter.

Industry analysts describe the two as "sister standards" rather than competitors. Both developed by the CSA, they perform distinct and complementary roles. Matter handles IP-based remote command control and smart home ecosystem integration — allowing users to remotely lock or unlock doors via app, manage user permissions, or trigger automation such as arming a security system when leaving home. Aliro, by contrast, governs the front-end interaction between a mobile device and a door reader, providing a unified digital key standard that lets users unlock their door simply by tapping their phone or watch against the lock using NFC, or by approaching with their device using ultra-wideband technology — no dedicated app required.

In essence, Matter manages the remote; Aliro handles the doorstep. Devices can support either standard individually or both in tandem. Samsung's March 2026 implementation offers a textbook example: users first configure their smart lock within Samsung SmartThings using Matter, then store an Aliro-based "digital home key" in Samsung Wallet for tap-to-unlock convenience in daily use.

Fortifying the digital door

As the primary physical barrier protecting homes, smart locks demand uncompromising security — and Matter's architects placed this at the centre of the design from the outset, implementing a multi-layered architecture spanning silicon to cloud.

At the chip level, NXP's EdgeLock SE051H secure element has achieved Common Criteria EAL 6+ certification, supporting elliptic curve cryptography, the NIST P-256 curve and the SPAKE2+ key exchange protocol to deliver a hardware root of trust for Matter devices. In Japan, MIWA has partnered with SEALSQ to develop the country's first Matter-compatible smart lock, leveraging the company's public key infrastructure services to establish trusted identity verification.

On the protocol layer, Matter mandates that every device carries a unique Device Attestation Certificate to prevent counterfeiting, while operational certificates issued by controllers ensure the authenticity of every link in the communication chain. The CSA has further extended security assurance to the consumer level with its "Product Security Verified Mark", requiring devices to pass a rigorous 32-page security specification review — giving buyers a visible seal of trust at the point of purchase. The Matter 1.4.1 release has improved bulk device provisioning, allowing a single QR code to simultaneously onboard a group of devices, while also enhancing Bluetooth responsiveness and stability. Combined with ongoing firmware update mechanisms, this provides manufacturers with an evolving security foundation.

A connected future takes shape

From dismantling ecosystem silos to rallying manufacturers around a common standard and hardening the security backbone, Matter is steadily reshaping the smart lock industry. As more affordable products reach the market and consumer awareness grows, the vision of cross-brand, plug-and-play smart lock experiences is rapidly becoming reality — one door at a time.
