FORD 2014 Flex v.1 - Manual (Page 88)

If your programmed transmitters or standard SecuriLock coded keys
(integrated keyhead transmitters only) 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 Integrated Keyhead Transmitter
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.

2. Turn the ignition from off to on. Keep the ignition on for at least three
seconds, but no more than 10 seconds.
