Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM).

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 vehicles equipped with TOD transfer cases may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.
full bulletin at NHTSA ↗When ordering a 2005 to 2008 remanufactured 5.4L 3v or 6.8L 3v engine, spark plug boots may be provided in the packaging. Replace all black spark plug boots from the original engine with the 'brown' spark plug boots, as provided. The updated 'brown' spark plug boots are longer than the black boots to accommodate a running change in the spark plug length. The ignition coil bodies and spring/resistor are transferable and only the rubber boots require replacement. Failure to install the spark plug boots provided with the replacement engine could lead to drivability concerns.
