The Yale Assure Lock 2 Keyed Smart Lock with Wi-Fi is a smart deadbolt lock built for the way you actually live. Push-button keypad on the outside. Full remote control on the inside. No Wi-Fi hub or bridge required. This digital door lock connects directly to your 2.4 or 5 GHz home network, giving you complete control with the free Yale Access App. Lock up, let a dog walker in, or get instant alerts the moment someone opens the door—whether you're upstairs or three time zones away. The backlit keypad makes code entry easy in any lighting, and unlimited codes let you share access with family, guests, or service providers. Set schedules, expiration dates, and track every entry from your phone. Auto-Unlock senses when you're home and opens hands-free. DoorSense® detects when the door closes and this automatic door lock secures it behind you. No second-guessing, no walking back to check. Fits most standard doors 1-3/4" to 2-1/4" thick with a 2-1/8" bore hole and 4" minimum center-to-center spacing between the deadbolt and knob. Grade 2 certified and built to operate from -22°F to 140°F, it'll protect your home for years to come. And for added peace of mind, a backup key is included.
