Universal LocKey / Lock and Key

Universal LocKey
Universal LocKey

The RFID technology and a haptic approach are applied in this innovation. The “Universal LocKey” employs a touchable index-matching way allowing users to quickly find out the correct key for door unlock. It could provide living conveniences not only for vision impaired people but also for persons in dark circumstances.
“Universal LocKey” also provides a rail-based lock design guiding keys to easily insert the keyholes for opening. The functions of the RFID pop-up point keys and rail-based locks solve problems of unlocking for most persons.
