I want three things from a smart lock: a slim, attractive design, more than two ways to control it, and the ability to connect to my smart home, with no single-purpose Wi-Fi bridge taking up an outlet in my house. Yale\u2019s flagship smart lock series,\u00a0the Assure Lock 2<\/a>, ticks all those boxes. Plus, they work with all the major smart home platforms if you add the right networking module, and they now come in fingerprint or Apple Home Key variants.<\/p>\n<\/div>\n The Yale Assure Lock 2 starts at $159.99<\/a>, the Assure Lock 2 Touch (from $199.99<\/a>) adds a fingerprint reader, and the Assure Lock 2 Plus (from $209.99<\/a>) has Apple Home Key. But you can\u2019t get both in one lock, which is a shame, and Yale still hasn\u2019t delivered on its promise of bringing Matter and Thread to its flagship locks. <\/p>\n<\/div>\n Each lock in the series is a full deadbolt replacement lock with the same ultra-slim exterior, the keyed models being slightly longer to make room for the keyway (overall, it\u2019s the smallest keypad smart lock I\u2019ve tested). They all share a nice, neat rear housing containing the four AA batteries and thumb turn (this is also one of the smallest I\u2019ve seen), and they can all be controlled with the built-in keypad or via Bluetooth using the Yale Access app (iOS or Android) or the Apple Home app (including Siri voice commands).<\/p>\n<\/div>\n Support for other platforms comes via Yale\u2019s ingenious swappable networking modules. The Wi-Fi module lets you connect to Amazon Alexa, Google Home, and others, while the Z-Wave module is for Ring Alarm, Samsung SmartThings, and other Z-Wave systems. Yale has said it will offer a module for Matter over Thread, but it\u2019s been delayed pending better support for locks within Matter<\/a>. <\/p>\n<\/div>\n
