Keynex turns an iPhone into a car key. Go to the car and it will open, step back and it will close. You don't need a keychain. • Open, close and start the machine from your phone. • Keyless: the threshold for opening and closing is adjustable. • Send the key to the person by name, for a day, a week, or forever. The days, hours, zone, and speed are configurable (Plus). • Give the key nearby, without Internet, even to a person without an account. • You can see who drove and when: the trip history and the current position. • Multiple machines in one application, each with its own name and illustration. • The status of the car in Dynamic Island and on the lock screen. • Sell or donate a car: the keys of the guests extinguish themselves.
