I have a question my truck is FX4 2004 , I dont have the code to open the doors and not have the owner's manual , anyone know where in the truck comes that code 5 numbers , greetings from mexico hopefully someone could help me !

 

Google "Owners Manual for 2004 F150", then download a free PDF version of an owners manual.

 

Even then, does all 2004 makes have same code? I doubt it. Even for reset you still need original code.

 

At one time wasn't the code posted to the backside of the back seat or something like that?

 

mine was on the computer behind the back seat.

removing the backseat is the tricky part...

 

Ran mine to local dealer. They reset it for me for free.

 

Local dealer can give it to you or reset. They just like to be sure it's your truck.. Hah

 

I got my dealer to pull my code. Had them walk me through changing it too

 

They ran out with a high speed laptop,hooked it up and asked me what I wanted my code to be. Told me it was usually like a $35 charge, but since I've bought from them a few times, it was on the house. lol
