E-JOYLOCK is an anti-theft protection for cars equipped with an electronic transmission, called by manufacturers "joystick" or "shift-by-wire". E-JOYLOCK is a gearbox lock that prevents the gear lever from changing position from "P" to "D", "N" or "R", thus protecting your car from theft and unauthorized use. Unlocking take place by connecting the lock to an application on a smartphone or a bluetooth chip.
