Common Causes of a Malfunctioning Key Fob

Dead Battery: The most common reason for key fob failure is a depleted battery. Key fobs rely on small batteries that eventually lose their charge.
Key Fob Programming Issues: Sometimes, the key fob can lose its programming, preventing it from communicating with your vehicle. This can occur after a battery change or due to other electrical interference.
Internal Key Fob Damage: Physical damage to the key fob’s internal components, such as from a drop or impact, can disrupt its functionality.
Receiver Issues in the Vehicle: In less common cases, the problem may lie with the vehicle’s key fob receiver. This could be due to a faulty antenna, wiring problems, or other electrical issues.

Check the Battery: Examine the key fob battery for corrosion or damage. Replace it with a fresh battery of the correct type.
