What are the reasons for the malfunction of the Buick Excelle remote key?

[JayceFitz]

Buick Excelle remote key malfunction is generally caused by the battery running low. You can open the remote key along the gap and replace it with a new battery. Below is relevant information: 1. Possible causes: The remote may be too far from the vehicle, the remote battery is dead or low on power, or there may be other vehicles or obstacles blocking the signal. Repeatedly operating the remote outside its range may require resetting the remote synchronization. If the central door lock control system is overloaded due to repeated operations within a short period, the power may be temporarily cut off, or it may be affected by external environmental radio signal interference. 2. Car central control: The car central control includes the central door lock system, allowing the driver to control all door switches and window lift systems. It also includes the central console, which houses various vehicle controllers such as the audio control panel.
