Aliro wants to fix the smart lock’s dumbest problem

You get home late. You’re juggling groceries, a backpack, and a dying phone. At the door, you try to find the app that controls this particular smart lock—Yale? Schlage? Kwikset? You open the wrong one, the lock doesn’t respond, and you dig through your home screen again, swearing under your breath.

It’s an all-too-common scenario for homeowners. Smart locks have come a long way but the user experience still feels stuck in the past. Each brand wants you to use its own app. Your modern lock may have replaced that messy ring of keys, but now you’re fumbling through apps instead—one for the front door, another for the back, maybe even a third for the garage—because there’s no shared language between them.

The same goes for digital keys. Apple’s Home Key works well, but only with Apple devices. Android users face more fragmented solutions, with support depending on the phone, the wallet app, and the specific lock in use.

Aliro, a new smart lock standard developed by the Connectivity Standards Alliance (CSA), aims to fix that by enabling one system that works with any phone, any lock, no special app required.

“Today, digital keys often feel fragile, tied to a specific app, requiring re-setup when phones change, or incompatible with other household members’ devices,” said Raj Sundar, senior director of product at XThings. “With Aliro, homeowners can expect digital keys to behave more like universal credentials.”

What Aliro does

To understand Aliro’s promise, we have to look at how we got here. Early smart locks used PIN codes, which didn’t identify the person unlocking the door and were difficult to manage securely. App-based systems brought digital keys, but made things more complicated — shared users often had to download a brand-specific app, create an account, and figure out a new interface just to get in. Access became tied to the lock’s manufacturer, not the individual user.

“Aliro solves this by standardizing digital credentials themselves, not just device control,” Sundar said. “With Aliro, a digital key lives in the user’s wallet and can move securely across devices, wallets, and platforms, instead of being trapped inside a single manufacturer’s app.”

Aliro also supports both tap-to-unlock and hands-free entry. The standard defines how the credential on your device securely communicates with the lock hardware, using a common set of rules that manufacturers can implement across platforms. Garrett Lovejoy, SVP and general manager of Connected Security at Fortune Brands Innovations—which owns Yale Locks—described the appeal as walking up to your door, hands full, and having it unlock without touching a thing—what he called a “Jetsons-like unlocking and opening experience.”

Core technologies in Aliro

Aliro relies on three wireless technologies already built into most phones and wearables:

NFC (Near Field Communication): Enables tap-to-unlock, similar to contactless payments. Hold your phone near the lock and it opens, no internet connection required.

UWB (Ultra Wideband): Adds precise distance sensing, allowing for hands-free unlocking. As you approach the door with your device in your pocket or bag, the lock can detect your proximity and unlock automatically.

BLE (Bluetooth Low Energy): Acts as a support layer, helping with setup or serving as a backup if NFC or UWB aren’t available.

Because Aliro is built around local communication, the system doesn’t rely on cloud services or a constant internet connection. You can unlock your door even if your Wi-Fi is down, your cellular signal is weak, or your lock brand’s app is acting up.

Aliro vs. Matter: Why a separate standard?

The CSA is the same organization that developed Matter. At first glance, Aliro might sound like something that belongs inside that standard. But while both are created by the CSA, they serve very different roles.

Matter was developed to unify smart home devices. It handles tasks like turning on lights, adjusting thermostats, and making sure your connected devices can talk to each other, no matter the brand. Its job is to manage connectivity and control across a local network. Aliro, on the other hand, is about access.

This difference matters. Access control carries a higher bar for security and reliability than most other smart home features. If a light fails to turn on, it’s an inconvenience. If a door unlocks when it shouldn’t—or doesn’t unlock when it should—that’s a serious problem.

“For the same reason that we have mobile payments standards, there’s standards for access as well that have to be separate and different,” Lovejoy said. “I don’t know if you would trust Matter to [make] a bank transaction for you. Probably not.”

Aliro was designed separately so it could meet those higher demands. It’s purpose-built for secure, real-time credentialing—something that couldn’t be layered on top of Matter without compromise.

What to watch for

For all its promise, Aliro won’t be a plug-and-play upgrade for every household or every lock.

One of the biggest hurdles is hardware. Because Aliro relies on technologies like NFC and UWB, most existing smart locks on the market won’t be able to support the standard without new radios. That means homeowners looking to adopt Aliro may need to replace their locks entirely, rather than update firmware or add accessories.

Battery life is another factor. UWB and NFC are both relatively low-power, but adding more radios and more frequent wireless communication can still impact how long a lock runs between battery changes. Manufacturers will need to balance performance and convenience without making users swap batteries every few months.

Security, too, is a moving target. Aliro is designed with strong encryption and local credential storage, but any system involving mobile credentials introduces new risks: how keys are provisioned, how devices are authenticated, and what happens when a phone is lost or stolen. Implementation matters, and it’s up to manufacturers to get it right.

Finally, while Aliro is platform-agnostic, integrating it cleanly into existing smart home ecosystems—especially those already running on Matter or proprietary hubs—will take time. Users will expect a seamless experience across devices and platforms, and any friction there could slow adoption.

From spec to smart locks

Aliro’s technical spec is complete, and the standard is now moving into the next phase: certification and implementation. The first Aliro-compatible smart locks are expected to hit the market in 2026, giving manufacturers time to design new hardware that meets the standard’s requirements. That includes adding support for technologies like NFC and UWB, as well as integrating wallet-based credential systems.

On the platform side, mobile OS providers appear to be laying the groundwork for Aliro-style functionality. Apple’s Home Key already operates in a way that mirrors what Aliro aims to enable universally: digital credentials stored in the wallet, unlocked with a tap or proximity. On Android, support is expected to flow through Google Wallet, which has begun adding digital credential APIs for access applications, Sundar said. When Aliro rolls out, users should be able to store and use digital keys natively, without needing a separate app tied to a specific lock brand.

Reliability is the real unlock

Aliro offers a path out of the fragmented mess of brand-specific apps, incompatible digital keys and uneven user experiences. It promises a future where unlocking your door is as seamless as tapping to pay, no matter what phone you use or which lock is on your door.

But Aliro’s true potential isn’t just standardization—it’s trust. “We end up with a product or an experience that is so standard and so developed that we have high reliability,” Lovejoy said.

That reliability, he argued, is what finally opens the door to wider adoption. Early adopters have tolerated smart locks that don’t always work perfectly. But most users won’t. When even the least technical person can walk up to a door, leave their phone in their pocket, and watch it unlock reliably every time, that’s when smart locks go mainstream.

Lovejoy compared it to the rise of the video doorbell. “That was Ring’s moment when they came up [with their doorbell] and they got that mass market,” he said. “They had this beautiful thing that anybody could click a button and they’d always be able to see who’s at the front door.”

Aliro could be the smart lock’s moment. Not a small step forward, but the leap that brings reliable digital access to everyone.
