Lost original key tow to dealer to connect new key they couldn't complete it. Tow the car back home then found the original key. Accessory lights came on at first then stop coming on. Int and ext lights come on doors lock and unlock and remote turn off the alarm. Horn and windows dont work no crank no start cant see the message center and there is a yellow steering wheel symbol light on. Car was working fine until after the dealer and a battery replacement. Need to know where to start diagnostic or reprogram key.
Thanks
