    Car auto-unlock typically works through a combination of radio signals and technology embedded in the key fob and the car’s locking system.When a driver presses the unlock button on the key fob, it sends a low-frequency signal to the car’s receiver, prompting the car to unlock if the signal matches its programmed code.This system utilizes rolling codes, where the code changes each time the button is pressed, enhancing security. For proximity-based systems, such as keyless entry, the car detects the key fob’s presence via radio waves when the driver is in close range, allowing them to simply touch the door handle for automatic unlocking. These technologies make accessing the car more convenient and secure while deterring theft through encrypted communication between the key fob and the vehicle.
