Hi, I purchased my 2004 F150 Supercrew used from a Ford dealer. It came with a 3 button keyfob. After some research I discovered it has the 2W7Z-19G364-AA Remote Start System w/Deluxe Vehicle Security and Keyless Entry Kit installed. I found an install manual and the owners manual for it and everything is there, according to the parts list and seems to be working properly except the remote start. I purchased the 4 button transmitter from Ford and tried to program it according to the instructions but it seemed like the override button is not working. I know it's connected because it will disarm the system. Does anyone have any suggestions as to what the problem might be. Thanks in advance.
