Where is the keyless entry code on 2002 grand marquis with no sticker in trunk?

If the keyless entry code sticker is not located in the trunk of a 2002 Grand Marquis, it may be found on the owner's manual, in the glove compartment, or on the back of the keypad itself. Additionally, the code can sometimes be retrieved by a Ford dealership or a locksmith with the proper tools and access to the vehicle's electronic systems. If these options are not available, consider checking for any hidden locations in the vehicle.
