Does anyone know what would make my Intelligent smart key to stop working ? I put a new battery in it but none of the buttons will work ,however if I have the key fob on my person I can manually unlock the doors by pressing the center button on the door handle and also manually open the trunk and sitting inside of car the engine will start as normal. My question is how do I get the fob buttons to work again, or is the key fob shot and do I need to get a new one? The one that I have is only 9 months old. Is there a easy fix for this or is there something that might be shut off that I don't know about? My second key fob that came with the car works fine, Anyone got any answers that I could try to get my intelligent smart key to start working like it is suppose to?
