Default Change factory keyless entry code.

Some @#$@#$ broke into my truck while I was out of town. No sign of forced entry and my wife swears she locked it and I believe her. She usually hits lock a few times until she hears the beep, drives me insane.

Anyway, one curious thing is the factory card that has the keycode on it was sitting on the passenger seat so I presume the guy plans to come back. So I need to change the factory keyless entry code. I can't seem to find it in Forscan and all I can find on google is how to retrieve the existing code. I found one post on the Forscan forum where one guy says the factory code can't be changed which must be wrong.

So can anyone help me out?

You do it in Sync 3, settings.

I don't have Sync3. I have a 4.2" display.

I think on Sync3 you can only add a personal code, not change the pre-programmed factory code. I need to change the factory code.

The factory code cannot be changed as far as I know. Maybe with a new BCM or PCM?

I thought I read that it could be changed but would reset to default if battery was disconnected.

If that is correct, that means that if the first owner saves the Factory Code, he could use it to access that vehicle, with no trace, forever.

That would be truly stupid.

I honestly don't see the need for that stupid keyless pad on vehicles with smart fobs. You can't leave it inside accidentally, unless you shield it in aluminum foil (or some other intentional method). Plus you can also unlock the truck with the Ford app if that ever happened, so why that pad? And yes, seems stupid that the truck can always be unlocked with the factory code. I also think that you can only ADD to the factory code, but changing the code on Sync3 doesn't remove the factory one, right? Some of us can easily try that. I changed mine, but haven't tried the pad at all. At least they can't drive the truck away, but could break into it.

If you do not like key pad, it can be removed and install XL trim, and wrap said trim as desired. I have done this on trucks of people that were afraid someone would obtain their number, or it can be disabled in BCM.

Another option is to pull the door panel and just disconnect the keypad. You can always plug it back in later if you sell or trade the truck.

I'm not sure exactly what's involved but I do know that even the dealer can't change the factory code.
