1. Insert the keys in the ignition then twist it OFF to RUN 8 times within 10 seconds, ending in OFF position (this is to put the system in programming mode for your new remote). You will know your system has entered the programming mode once the door locks cycled (lock then unlock).
(Note: When the first keyless entry remote transmitter is programmed, all existing keyless entry remote transmitters are erased.)
3. Repeat step 2 immediately for each transmitter that will operate the vehicle including your old ones (if any.)
5. After programming the remotes ofcourse you will need to exit programming mode. To do that, you will need to twist the key in the ignition to OFF or wait up to 30 seconds for the system to turn program mode itself.
