I'm using forscan to change somethings in the car like 'Auto lock" which worked fine but I want to silence chimes for seat belts. The data to do this does not show up as well as the lighting codes. Does anyone know if
these features are even available in the 2003 Grand Marquis. Seems like a lot more data should be coming up on Forscan. Also I could use the spreadsheet for this model. One more thing,the key fob won't program. I've done the 4 key turn thing and the locks cycle but pressing the button on the fob does nothing. I've been told that that function has to be enabled in the programming using FORSCAN but nothing with that subject shows up on my computer when using FORSCAN. Any thoughts. P.S. the battery in the fob is good and the fob is brand new from Locksmiths ,com. Thanks Dan
