I just traded my 2004 6.0L F250 for a 2009 F350 with the 6.4L, unfortunately it did not come with the card for the factory door code. I know from searching here that there have been quite a few threads concerning locating the code, but I have been unable to find one for these newer model trucks ie: ('08 - '10). Is it still up under the dash, or behind the back seat or on the side of the radio? If anyone has any experience with this I would really appreciate the help, I would rather not have to go to the dealer if it's something I can find on my own. I messed up and posted this in the 6.0 forum also but thought it would be better suited here. Thanks in advance for any info.

 

Do you have an owners manual. seems to me there is a procedure in there to set or re-set. I think they were all preset on the same code, then the owner changes it. But I'm doing this from memory and at my age that's a dicey exercise.

 

The owners manual says the code is located on the computer module, and I am pretty sure it is a unique number. Thank you for the reply though.

 

The code for the Keyless Entry is printed on the smart junction box label located on the back side of the module. It is located by removing the passenger cowl side trim panel.

 

Thank you, I know this sounds stupid but where exactly is the passenger cowl side trim panel?
