The long-delayed smart lock standard Aliero is finally launching. According to the Connectivity Standards Alliance (CSA), the first specification, which standardizes NFC-based tap-to-unlock and UWB hands-free unlocking for smart locks, will arrive early this year.
“We are pleased to share that Aliero, CSA’s standardized credentialing and communications protocol that lets trusted smartphones and wearables act as digital keys with smart locks and readers in your home and where you badge, has passed its final verification milestone and will come to market in the first quarter of 2026,” said Nelson Henry, chair of the Aliero Steering Committee. The Verge In an emailed statement.
Announced in 2023, Aliro is an open standard for smart locks and digital keys that provides a standardized way for smart locks to communicate with smartphones and watches, regardless of manufacturer or platform.
Ultimately, this should mean that more locks and more phones will get capabilities similar to Apple’s Home Key feature on the iPhone. This lets you use your iPhone as a digital key for tap-to-unlock using NFC, just like you do tap-to-pay. More recently, Apple added a UWB-powered hands-free unlocking option that unlocks your door as you approach.
With Aliro, these features can now come to Android phones and other smart home platforms, so if your spouse or house member uses a Galaxy or Pixel phone, you can both unlock the same smart lock using your device as a key.
Alero is an industry-wide collaboration developed by Apple, Google, and Samsung with lock manufacturers and chip makers, including Allegion, Assa Abloy, Qualcomm, and NXP. Several lock manufacturers have announced that they plan to support Aliero, including Schlage, Kwikset, X-Things/U-Tech, Level, and Nuki.
ELIRO-certified locks will use one or more communication options to unlock compatible doors:
According to CSA, Aliro’s advantage over similar solutions is that it provides direct, secure communication between the phone or wearable item and the lock. No apps needed to be opened, and no cloud involved; Credentials are stored on the user’s device, and the communication between the device and the lock uses asymmetric encryption. Because it doesn’t use the cloud, it will work when your phone is offline or doesn’t have service, just like a regular key.
Henry says CSA has made significant progress over the past two years by creating the Aliero 1.0 specification, its certification program and supporting testing system. This should be poised for rapid, widespread adoption, and we may soon start seeing smart locks with Aliro support.
