My '05 Lariat has keyless entry,but I don't have the access code.Bought truck used from a financial institution.The owners manual states that the code is marked on the PCM,(5 digit #),but I can't find a separate # other than the usual cal. and part #'s. Am I missing something,or is there another computer located someplace besides under the hood that controls other functions of the truck.I would rather stay away from dealer's if I can.Thanks for any help.Great forum,Jim.

 

Take a look at this thread: https://www.f150online.com/forums/20...igit-code.html

You may have to remove the back seat to get to it.

 

I removed the back seat to retrieve mine. And BTW, this is probably not the correct section for this topic.

 

Moved to 04-08.

 

x2, the code is on the module behind the rear seat. There are posts on how to remove the back seat cushion.

 

I am guessing you dont have the card that comes with the owner's manual?

 

Mine was a card in my user's manual as well
