where do I get a "scan tool"?

Just to add to this one if the key fob was working with your car you can try reseting it by going by the car holding the lock and unlock buttons down at the same time for about ten seconds if it resets you will hear the car lock and unlock and the horn will honk.The scan tool you won't find anywhere then the dealer most likely it takes a tech2 scan tool with the correct software.If its a new remote and you need to program it a dealer is your best bet.
