• Weak Key Fob Battery: A dying battery can disrupt the signal between the key fob and the car.
• Faulty Key Fob: The transponder chip in the key fob can malfunction, preventing communication.
• Ignition Switch Problems: A failing ignition switch can prevent the car from recognizing the key.
• Wiring Issues: Damaged or corroded wiring can disrupt the anti-theft system’s circuitry.
