Something is wrong with my sponsor page or I would have posted before Todd!
Adding Duplicate Keys (Requires two working keys)
1. Insert an existing key into the ignition cylinder.
2. Turn the ignition cylinder to on / run and back to OFF.
3. Remove the existing key and, within five seconds, insert a second key and turn it to on / run - then back OFF.
4. Insert the new key before ten seconds have elapsed and turn it to on / run.
Leave it on for one second and turn back to OFF.
5. The security light will be on for three seconds to indicate that the new key has been programmed properly.
