Ok , I just found out after dropping by my local Ford dealer that the code I have is not the original.That is why I can't reprogram or erase the codes. I am going to take it by next week and they will have to go into the diagnostics and find the code for me. She told me that it would be $60 . Does anyone know how to get a lost code without this being done.

Backseat removal took me about 15 minutes. 12 of those Minutes was trying to release a latch. Watch YouTube video and do it that way. $60 saved.
