Which button locks the car doors from inside?

[LeWeston]

In the car, the button to lock the doors is the central locking button. Here are the relevant details: 1. Introduction: The central locking system inside the car refers to the switch located on the driver's door, which can simultaneously control the closing and opening of all car doors. Most central locking switches consist of a master switch and sub-switches. The master switch is installed on the driver's door, allowing the driver to lock or unlock all doors; the sub-switches are installed on other doors, enabling individual control of each door. 2. Wireless remote function: The wireless remote function of the central locking system allows doors to be locked and unlocked from a distance without inserting the key into the lock. Its greatest advantage is that, regardless of day or night, there's no need to locate the keyhole, enabling convenient remote locking and unlocking.
