Why is My Key Fob Dead?

- Key Fob Programming Issues: Sometimes, the programming linking your key fob to your car can become corrupted. This can happen after a battery change or due to electronic interference.
- Internal Key Fob Damage: Physical damage from drops or water exposure can damage the internal components of your key fob, rendering it useless.
- Car Battery Issues: While less common, a weak or dead car battery can sometimes interfere with the key fob’s signal. If your car battery is struggling, it might not be able to receive the signal from your key fob.
- Key Fob Range: You might simply be too far from your vehicle for the key fob to work effectively. Ensure you are within the specified range of your car.
