What are the reasons why the remote key of Besturn X80 fails to function?

[ManuelMarie]

Here is an analysis of the reasons why the remote key of Besturn X80 fails to function: 1. The key battery is dead: A dead key battery is the main reason why the remote key fails to lock or unlock the car. In this case, simply replace the key battery with a new one. After replacing the battery, the key must be reset; otherwise, it will not function properly. 2. The sensing distance is too far: When the distance between the key and the car is too far, the sensing device on the key cannot connect with the car, leading to failure. In this situation, simply get closer to the car before using the remote key. 3. Signal interference: If the car is parked near a broadcast tower or in an area with many electronic devices, the remote key may also fail to function. In this case, use the mechanical key to lock or unlock the car. 4. The car sensor is damaged: If the key battery is sufficient and there is no signal interference, but the remote key still fails to lock or unlock the car, it is likely that the car sensor is damaged. In this situation, take the car to a repair shop or 4S store for professional inspection and repair.
