FORD 2015 Expedition - Manual (Page 81)

Replacement Keys
Note: Your vehicle may come with two integrated keyhead transmitters.
The integrated keyhead transmitter functions as a programmed ignition
key that operates all the locks and starts the vehicle, as well as a remote
control.
If your programmed transmitters or standard SecuriLock coded keys are
lost or stolen and you do not have an extra coded key, you will need to
have your vehicle towed to an authorized dealer. The key codes need to
be erased from your vehicle and new coded keys will need to be
programmed.
Store an extra programmed key away from the vehicle in a safe place to
help prevent any inconveniences. See an authorized dealer to purchase
additional spare or replacement keys.
Programming a Spare Key
Note: A maximum of eight coded keys can be programmed to your
vehicle. Only four of these eight can be integrated keyhead transmitters.
You can program your own integrated keyhead transmitters or standard
SecuriLock coded keys to your vehicle. This procedure will program both
the engine immobilizer key code and the remote entry portion of the
remote control to your vehicle.
Only use integrated keyhead transmitters or standard SecuriLock keys.
You must have two previously programmed coded keys and the new
unprogrammed key readily accessible. See your authorized dealer to have
the spare key programmed if two previously programmed coded keys are
not available.
Read and understand the entire procedure before you begin.
1. Insert the first previously programmed coded key into the ignition.
2. Turn the ignition from off to on. Keep the ignition on for at least three
seconds, but no more than 10 seconds.
3. Turn the ignition off and remove the first coded key from the ignition.
4. After three seconds but within 10 seconds of turning the ignition off,
insert the second previously coded key into the ignition.
5. Turn the ignition from off to on. Keep the ignition on for at least three
seconds, but no more than 10 seconds.
