Apple’s protocol for digital home keys has served as the basis of a new industry standard for smart locks and digital keys, dubbed Aliro.
Aliro promises to allow people to use their iPhones and Android smartphones to open compatible smart locks without launching any app, with just a tap.
The protocol takes advantage of three modern radio technologies to establish a secure connection between a digital home key and a smart lock: Near Field Communication (NFC), Bluetooth Low-Energy (BTLE) and Ultra-Wideband (UWB).
Apple’s Home Key powers the Aliro smart lock standard
Developed by the Connectivity Standards Alliance (CSA), the same industry body behind the Matter smart home protocol, Aliro has the backing of major technology companies and makers of smart devices for the connected home, including Allegion, Apple, ASSA ABLOY, Google, Infineon, Kastle Systems, Last Lock, NXP Semiconductors, Qualcomm, Samsung and STMicroelectronics.
A press release in the CSA Newsroom notes that Aliro should kick off widespread adoption of smart devices to unlock doors and openings “by enabling a consistent experience across certified hardware.”
Apple currently supports digital home keys (along with digital car keys) in the Wallet app on the iPhone and the Apple Watch. To unlock any HomeKit and Matter-compatible lock, you just bring your device near it. You can also hold your device near the lock and then use Face ID or Touch ID to unlock it.
The redesigned Home app also supports temporary sharing of home keys with other people, as well as setting up access codes for folks needing quick access to your home. Further information about home keys is available on Apple’s website.
