2012 FORD EXPLORER ECU

Theintegrated keyhead transmitter (IKT)functions as both a
programmed ignition key that operates all the locks and starts the
vehicle, as well as a remote keyless entry transmitter. A maximum of
eight coded keys can be programmed to your vehicle; only four of these
eight coded keys can be IKTs with remote entry functionality.
Theintelligent access keyfunctions as both a programmed key that
operates the driver door lock, activates intelligent access with push
button start systems as well as a remote keyless entry transmitter. A
maximum of four intelligent access keys can be programmed to your
vehicle.
If your programmed transmitters or standard SecuriLockcoded keys
(IKTs only) are lost or stolen and you don’t 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.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare integrated keyhead transmitter (IKT) keys
If you have intelligent access keys, refer toProgramming spare
intelligent access keysin this section.
You can program your own integrated keyhead transmitters or standard
SecuriLockcoded keys to your vehicle. This procedure will program
both the engine immobilizer key code and the remote entry transmitter
portion of the IKT to your vehicle.Note:A maximum of eight coded
keys can be programmed to your vehicle; only four of these eight can be
IKTs with remote entry functionality.
Tips:
•Only use integrated keyhead transmitters (IKTs) or standard
SecuriLockkeys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If two previously programmed coded keys are not available, you must
take your vehicle to your authorized dealer to have the spare key(s)
programmed.
Please read and understand the entire procedure before you begin.
