Battery Issues

The most common reason why a car won't detect a key fob is because of a weak battery. Over time, the battery in a key fob can wear down and lose its charge, preventing it from being detected by the car. You can easily replace the battery in your key fob and get it working again.

Faulty Wiring

If your car still isn't detecting your key fob after replacing the battery, then the problem could be with the wiring. The wiring of your key fob can become damaged due to wear and tear, or it can be damaged by water. If the wiring is damaged, then it will need to be replaced for the key fob to work properly.

Out of Range

The range of a key fob is limited, and if it's too far away from the car then it won't be detected. Make sure that your key fob is within range of the car when you try to use it.

Sensitivity Issues

Some key fobs are more sensitive than others, and if yours is not sensitive enough then it won't be detected. If this is the case, then you can try adjusting the sensitivity of the key fob or replacing it with a more sensitive model.
