8. Turn the ignition to the OFF position.
9. Release the power UNLOCK button on the door panel. The vehicle should respond by door locks locking and unlocking automatically. (If locks do not cycle after you let go, not before you let go of the unlock button, then the vehicle has not entered programming mode and you must start the procedure over.

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and unlock. This may take up to 30 seconds.
11. Repeat step 10 now for each additional remote (including any existing remotes).
