The car's receiver is broken and cannot receive signals. It is recommended that the owner visit a repair shop for a detailed inspection based on the specific situation. The remote key utilizes the wireless remote control function of the central locking system, allowing doors to be opened and locked from a distance without inserting the key into the lock. Its working principle involves emitting a weak radio wave from the key, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator performs the opening and locking actions. The Audi Q3 comes in various models, with different body dimensions for each. Taking the 2019 Audi Q3 as an example, it is available in two body styles: the Elegance version and the Sport version.
