NHTSA's summary

INTELLIGENT KEY SYSTEM CHANGE SERVICE INFORMATION The applied vehicles have undergone changes to the Intelligent Key system to improve vehicle security. The changes involve a different security protocol, commonly known as cryptology. IMPORTANT: - The two systems use a different Intelligent Key, BCM, and Intelligent Key antennas. The components of the new and old systems are NOT interchangeable. - Once an Intelligent Key is programmed to a vehicle with the NEW Intelligent Key system, it cannot be reprogrammed to any other vehicle.
