Hi Everyone, I have a problem with one of my Smart Keys. Car was purchased used with 2 smart keys one of which had a lot more wear than the other. One is working just as it should. The worn one stopped working except when it is inserted in the dashboard key slot. I replaced the battery and now the red LED flashes with all 3 buttons; however they do not Lock, Unlock, or Panic anymore! Car does not respond at all! I have read that the keycode is unique to the key fob and that code ought to be already accepted by the car. What do I have to do to get this key working again? I am getting a new aftermarket shell and plan to make the key look better and replace the missing red button.
check the voltage of the new battery, and make sure no buttons are stuck down, take it apart and look for problems.
