• Keep Keys Away from Exterior Walls: Storing keys in the center of the home makes it harder for signal boosters to reach them.
• Disable Keyless Entry: Through the MMI (Multi-Media Interface) settings in some designs, owners can disable the "Advanced Key" proximity function, needing a physical button press to unlock the doors.
