Why is my Toyota Yaris key not detected?

Possible Reasons for Key Not Being Detected
There can be several reasons why your Toyota Yaris key is not being detected. Here are some possible explanations based on the search results:
1. Dead Key Fob Battery: One of the most common reasons for a key not being detected is a dead battery in the key fob. If the battery is dead, the key fob won’t be able to send signals to the keyless entry system. You can try using the spare key fob if available, or use the provided key embedded in the fob to unlock the door and start the engine.
2. Low Car Battery: Another possible reason is a low car battery. If the car battery is low, it may not be able to receive signals from the key fob. In this case, you may need to charge or replace the car battery.
3. Faulty Keyless Operation System: If the keyless operation system in your Yaris is faulty, it may not be able to detect the key fob. In such cases, it is recommended to consult a mechanic for further diagnosis and repair.
4. Using the Wrong Key: It’s important to ensure that you are using the correct key for your Yaris. Using the wrong key can prevent the car from detecting the key fob.
5. Other Factors: There may be other factors that can cause the key not to be detected, such as interference from other electronic devices or a malfunctioning keyless entry system. If none of the above solutions work, it is advisable to contact a Toyota dealership or a qualified automotive technician for assistance.
