A few years back, the tease of a Nest and Yale smart lock began with the promise of the Linus lock. That project never made it to market, and the two companies regrouped for the Nest x Yale Lock. Specifically designed to work with the Nest line of products, the Nest x Yale Lock is designed to do things like disarm your Nest Secure ($499.00 at Dell Home) system when you unlock the door and lock the door when Nest detects you're away.

The $249 lock is a collaborative effort between Nest and Yale, not to mention Nest's first foray into smart locks. Add it to the long list of other Nest products: the new Nest Hello ($229.00 at Walmart) doorbell, Nest Secure alarm system, Nest thermostats and Nest cameras, and there's now an entire smart home product suite under one brand. With Yale's solid line of smart-lock hardware and the software pedigree of Nest, this lock is ideal for anyone who's already bought into the Nest ecosystem.

The Nest x Yale Lock replaces your existing deadbolt. Like the Yale Assure SL Touchscreen Deadbolt we tested last year, the Nest x Yale Lock keeps Yale's keyless smart-lock styling and comes in polished brass, oil-rubbed bronze or satin nickel. Also like other Yale models, it comes with detailed printed instructions and a helpful app called Bilt to walk you through the installation process.
