Google’s Nest Protect Smoke Alarm and the Nest Yale Door Lock Are Getting Discontinued — Get Them While They’re On Sale Now

The good news? They’re now marked down up to 53% off.

Google officially announced last week that it would discontinue two longstanding flagship smart devices in 2025: the Google Nest Protect and the Google Nest x Yale Lock. The two devices represent monumental advancements in smart tech since each launched in 2013 and 2018, respectively. Why the move? Google is now shifting its focus to joint partnerships with First Alert and Yale to produce the First Alert Smart Smoke & Carbon Monoxide Alarm and the Yale Smart Lock with Matter, which will eventually supplant Google’s marquee smart home options.

“We’re ready to pass the torch to our partners, enabling them to lead the future of smart home safety through continued innovation,” Google announced in a statement disseminated in the Nest community forum.

First Alert, a Resideo-owned company that’s an industry-leader in fire safety and carbon monoxide products, will partner with Google to create an interconnected network of home fire safety systems that will sync with current Google Nest products. The First Alert Smart Alarm, like other Google Home products, will connect directly to the Google Home app, and allow the user to voice control and send the user customized alerts and specified notifications.

“A truly helpful home requires a rich ecosystem of devices and experiences that we can’t build alone,” Google mentioned.

According to the company, the First Alert Smart Smoke & Carbon Monoxide Alarm will retail for $129 and be available in the US and Canada later this year.

The Yale partnership has been longstanding—the two initially collaborated back in 2018 to develop leading smart lock technology via the Nest x Yale Lock. The smart lock, which allows users to manage personal passwords, receive lock push notifications, and unlock their door remotely, amongst other groundbreaking features, is being phased out in favor of the Yale Smart Lock with Matter, which Google describes as a “smart lock designed to complement Nest doorbells coming this summer.”

The new Yale Smart Lock will now be compatible with all Matter-compatible devices via the Thread networking protocol, such as Apple Home, Amazon Alexa, and Samsung SmartThings.

Google also announced that both options will still be available while supplies last, somewhat quelling the fears of those who prefer the legacy models. Following Google’s announcement, the pair of devices is currently on sale on Amazon: the Google Nest Protect and the Google Nest x Yale Lock are 18 and 58 percent off, respectively.

According to Google, the Nest Protect will still receive on-schedule security updates and work to full functionality through its 10-year expiration date.

While some recent complaints have suggested that scarcity is the biggest issue surrounding the second-gen Google Nest Protect—an issue that will only get worse in the coming months—it’s currently in stock on Amazon and for $35 off, to boot.

Much like the Nest Protect, Google says the Nest x Yale Lock will continue receiving regular updates and work to full capacity. And considering you won’t have much longer to purchase either smart device, now is certainly a good time to take advantage of the additional savings on Amazon, before both products become hardwired relics in time.
