Because it's not an original factory product, there are quality issues. Below is the relevant introduction: 1. Uses: The uses of a car's central control display screen include: visible reverse image, DVD playback, and navigation. 2. Functions: The central control includes the central door lock system, allowing the driver to control the opening and closing of all car doors and the window lifting system through the central control. It also includes the central console, audio control panel, and various other vehicle controllers. There are many types of central locks installed in cars, but their basic components mainly include the door lock switch, door lock actuator, and door lock controller. 3.

Just press the remote control lightly, and any car can be equipped with a central lock.
