Sesame Smart Lock. Your Key, Reinvented (Champagne Silver)

Sesame is the most easy-to-use robot that transforms your traditional single cylinder deadbolt to a smart lock under a minute. Our five-patented self-adjusting design will make the installation like a breeze with no tool required. Feel free to add unlimited number of guests access for your good friends and family for free.

• Leave your keys behind: Lock/unlock your door using the App. Better yet, open Sesame with a knock.
• Share access: Allow guests in. Control who has access and when.
• Log records: Receive a notification whenever your door opens or closes.
• Installs in seconds: Simply tape Sesame to your door with a single strip of 3M Command tape (supplied) without removing or swapping anything. No tools required. Sesame works with just any single cylinder deadbolt in the US/Canada thanks to five-patented mechanisms.
• Long battery life: Sesame lasts about 500 days on lithium batteries (supplied).
