Changing door code

So i just bought my raptor and the previous owner never used the door code lock. i dont have a manual for the truck either. how do i find the dealer code or reset the door code? ive searched and only found how to reset if you have the original. thanks

 

Search YouTube for “F150 door code with two keys”

 

I found it in my passenger footwell fuse box. The two key method didn't work for me.

 

I have a similar but related question. Is there a way to erase (or change) the door code that comes factory installed? Reason I ask is that "coincidentally" a few days after my truck came back from service, someone broke into my truck. Picture wasn't good enough to identify the perp, but my Nest camera caught it on tape and the guy clearly used a code to unlock the door. To be fair, I'm the idiot that left the card with the code in the owners manual inside the truck so I guess this is somewhat deserved.......

 

the module is in the passenger footwell. on the back side of it, there is a sticker with the factory code

 

op, i found my code down inside passenger kick panel.

and i too would like to change the door code
