    As described in several threads, I purchased a new fob for my 2004 Prius with Smart Key. I still had a working, fully functioning original and wanted a second for backup purposes. Using the chicken dance method described in the videos and other threads, I was able to successfully program the new fob.
    My problem is that the original key now will not work to start the car. Although it can open all doors and works when plugged into the dash to power the car, when I push the start button when the fob is not in the dash, I get the amber key with exclamation as if it is not finding a recognized fob. I figure I must of somehow unregistered the fob but it still does open the doors and locks in the smart key manner.
    Thanks in advance for any ideas.

    Sounds like a weak battery in the fob. You did not unregister in the car's computer (which I think would be an impossible result of the Chicken Dance anyway) if it still works when plugged into the dash.
