2001 Expedition XLT keyless entry

I was wondering where the keyless entry code would be located on this vehicle just bought it from a used car lot and would like to know just in case i lock the keys in it or something. thanks

Most Fords have a sticker on the PCM, main computer. Then a second sticker in either the glove box or on the inside frame of the rear hatch for the Expedition. Barring that, you can go to Ford but they usually charge for it.
