The Yale Assure Lock SL is the slimmest smart lock on the market, featuring a sleek back-lit touchscreen keypad that provides convenient, key-free access to your home. Built-in Wi-Fi and Bluetooth connectivity allow you to lock or unlock your door, share access, and monitor entry activity from anywhere using the free Yale Access app — no additional hub required, as the Connect Wi-Fi Bridge is included.

The auto-unlock feature lets the door open automatically as you approach, and auto-lock ensures it secures itself once closed. You can create and manage unlimited entry codes, assign virtual keys to family members and trusted guests, and schedule access windows through the app. A 24/7 activity feed and real-time push notifications keep you informed of who enters and when.

Installation requires only a standard screwdriver and fits doors 1-3/8" to 2-1/4" thick with a 2-1/8" face bore and 2-3/8" or 2-3/4" backset. The lock is rated BHMA Grade 2 (ANSI/BHMA A156.36) and is tested to withstand weather conditions from -22°F to 140°F outdoors. It works with Google Home, Apple HomeKit, Amazon Alexa, Samsung SmartThings, and Philips Hue. Model YRD256-CBA-619 in Black Suede finish; powered by 4 AA batteries (included).
