https://www.cnet.com/news/alexa-can-unlock-your-schlage-smart-lock-now/ >Amazon's Alexa already lets users lock compatible smart locks with a voice command. Voice unlocking, however, is a trickier sell -- after all, no one wants a thief to whisper an unlock command through a cracked window in order to get in, and no lock manufacturer wants to create the appearance of a vulnerability, either. >That's why, up until now, Amazon hasn't included voice unlocking as a feature of Alexa's smart lock software -- but that's changing today. Starting now, compatible smart locks can offer voice unlocking through that native Alexa software, which means that they don't need to craft a custom skill of their own in order to do it, like August did last year. At least one manufacturer, Schlage, plans to take advantage immediately, with voice unlocking available today for its Schlage Sense and Schlage Connect deadbolts.
