Had the same problem about a week ago and been runnin round to find an answer! This is a good website http://www.mirez.co.uk/KeyProg.htm
Just a thing to note is at the 4th time moving key to ignition point, leave there until the light stays on the led next to the clock. Once this is confirmed (you might hear a beep as well), continue the rest of the steps and you should be up and running!
Good luck
