Blustone...check the Owners Manual, it has the method done step by step.
TO CLARIFY, since no one likes to explain things CLEARLY on this site:
If the little red car with the key on it (aka security indicator) is flashing even AFTER you start the vehicle and stays on while driving, that means your vehicle is still in "programming mode" for keys.
To exit the vehicle from programming mode (i.e. stop it from flashing), you must:
Insert a recognized key. Rotate the key from the "off" to "on" position FIVE (5) times within TEN (10) seconds. The security indicator light (lil red car) should turn off after last turn.
Go ahead and start 'er up... the red light should not longer be blinking.
