Button functions (standard icons on this design)
Top-left (closed padlock): Lock — locks all doors and usually arms the alarm.
Top-right (open padlock): Unlock — unlocks the driver’s door (or all doors, depending on the vehicle settings). A second press often unlocks the remaining doors.
Bottom-left (sun/light rays icon): Typically activates exterior lights (to help locate the car in a parking lot), flashes the lights, or serves as a panic/alarm button on some models.
Bottom-right (car with open trunk): Trunk/boot or liftgate release — unlocks or opens the rear cargo area (often requires a short hold to prevent accidental presses).
