For the more forgetful and careless among us, KeyMe‘s got you covered. The app allows users to scan a picture of their keys with their phone and upload them into the cloud. Afterwards, any locksmith can make a physical copy of the digital keys by following the on-screen instructions. Users can also mail-order copies of their keys and even send the digital file over to friends. The app is only available for Apple devices at the moment although Android and Windows Phone versions are in the works.
Check out the app in action below and download your copy for free here.
