89786-08020 is the part number for the key blank itself and theplastic housing. 89070-71140 Is the part number of the entire key assembly withthe transmitter/immobilizer and remote control functions built-in. I was unableto locate any frequency information on the new key assembly. If you just needthe steel blank with the remote functions to transfer from your other key it ischeaper to buy the steel blank with the plastic head and transfer over thecomponents within the key itself. Click the link below for more information and the updated part number that is available in the aftermarket. Let me know if this helps. I will be going off-line a few minutes.
