Sorry about that! If your Sesame is already registered to your email address, just let us know your Sesame account email address and we can look it up in our database.
If your Sesame is not yet registered to your account, you would need to click on the plus sign in the sidebar to get to the "Find Your Sesame" screen and the Sesame serial number will be listed there. If you can't find your Sesame in the list, you may need to reset your Sesame. Hope this helps! - CANDY HOUSE
