The Tesla Model 3 keycard has had polarising opinions from the very beginning, but theres no denying that is a pain in the ass to use. In fact, even Musk was quoted saying, We really need to provide a normal key to the customers of the car. The answer to this a key fob -was leaked, thanks to an FCC application. The key fob is now available at Teslas website for $150, but dont rush over there just it - its already sold out.
