That is not true. Mine works just fine. Precision did tell me that if it doesn't work after reconnecting the SKREEM, you would have to re-synch it to the car. I did not have to do that as it worked right off the bat. I do not have the CAN bus wires nor the halo wires hooked up - only the large top connector is hooked up, so I don't believe the ignition halo has anything to do with it. Keep trying to re-synch your FOB.
