remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.

security message went on due to how quickly the key
is programmed.

be programmed.
If you are ever driving and the security message comes on
and stays on, you will be able to restart your engine if you

turn it off. Your PASS Key III system, however, is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by the PASS
