Kia Optima Won’T Start Key Not Detected

If your Kia Optima won’t start and the key isn’t being detected, you may have a bigger issue than expected. You may have a broken key blade or bad connection between the key and the car. There are a few steps you can take to make sure it is a bad connection instead of an electrical issue with the car itself. Firstly, check to see if the key is inserted correctly into its slot. If it is properly inserted and still isn’t being detected, then you can move on to checking the connections between your Kia Optima and the key. Make sure that the battery in your key is charged, as this could also be preventing the signal from being detected by your vehicle.
