Star Flash introduces the "phase difference ranging" algorithm, which accurately calculates the real-time distance between the user and the vehicle by analyzing the phase changes of the signal.

The positioning accuracy is 5 times or even higher than traditional Bluetooth keys, which can accurately determine whether the car key is inside the car, achieve precise welcome and unlocking, and solve the pain point of users being fined to stand outside the car.

Through stable positioning accuracy, the locking accuracy is 6 times higher than traditional Bluetooth keys, ensuring that when the user leaves the vehicle and triggers the locking door, the vehicle can be locked in a timely manner, improving vehicle safety.

At the same time, it has strong anti-interference ability. Even in scenes where the human body or objects are obstructed, such as placing the star flash device in a pocket or backpack, the fluctuation of its positioning accuracy is controlled within a very small range, which can maintain a stable interactive experience.

And Star Flash SLE can simultaneously test 4 "channels", which is more efficient than Bluetooth, more accurate in measurement at the same time, and shorter in testing time at the same accuracy. When multiple people use the digital car key to get on the car at the same time, the unlocking speed is faster, the bandwidth is larger, the speed is higher, and the latency is lower.

At present, the Star Flash car key has been installed on some models, such as the 2025 Wanjie M9 and Zunjie S800. When used in conjunction with the Huawei Pura80 series or Huawei WATCH 5 watch, it will have a very good experience.
