I have a 2016 Kia Optima. This started a few months ago. My drivers side door doesn’t lock unless i manually lock it by using the button on the handle. It doesn’t lock from the key fob or the buttons on the door. When i do manually lock it, it doesn’t unlock with the key fob either. so it results in me climbing through my car from the other doors to unlock it. I need my doors to lock as i just moved to a big city with a higher crime rate then my small town. please help me!!
