I am trying the add mode one and getting past the e step but at f I press the buttons as it says but no response. What am I doing wrong?

im having the exact same issue on my 98. i cant get past step G. mine cycles twice to indicate that it was unsuccessful. However my key will start the car. That part was succesful. Still cant get it to unlock/lock the doors. Please let us know if you are able to get it to work.
