2012 FORD FOCUS ECU

Intelligent access (if equipped)
Your intelligent access system uses a radio frequency (RF) signal to
communicate with your vehicle and authorize your vehicle to unlock
when commanded (either by touching the inside of any exterior door
handle, the luggage compartment handle, or a button on the transmitter
itself). If excessive RF interference is present in the area, or if your
vehicle battery is low, it may be necessary to mechanically unlock your
door. The mechanical key blade in your IA key can be used to open the
driver’s door in this situation (refer toIntelligent access keyin this
chapter for more information on the location and use of the mechanical
key blade).
Your vehicle will allow you to unlock and enter your vehicle without
actively using a key or transmitter. You can use the intelligent access
feature at any door or at the liftgate. You can activate the intelligent
access feature as long as you have one of your IA keys within range of
the front doors or the liftgate.
Activating intelligent access at the doors:If your IA key is within
3 feet (1 meter) of the doors you can activate your intelligent access
system by touching the inside of any exterior door handle. The door(s)
will automatically unlock and the door can be opened.
To lock the doors, press the lock area (black spot) on either front door
handle.
Activating intelligent access at the liftgate:If your IA key is within
3 feet (1 meter) of the liftgate, you can activate your intelligent access
system by pressing the exterior liftgate release button, hidden under the
trim above the license plate. The liftgate will release and open.
Push button start:The push button start system allows you to start
your vehicle without using a key. Refer toPush button startin the
Drivingchapter.
Unlocking the doors/two-stage unlock
1. Pressand release to unlock the driver’s door.
Note:The interior lamps and turn signal lamps will illuminate.
2. Press
and release again within three seconds to unlock all the
doors. The turn signals will flash.
The remote entry system activates the illuminated entry feature; this
feature turns on the lamps for 25 seconds or until the ignition is turned
on.
The battery saver feature will turn off the lamps 10 minutes after the
ignition is turned off.

equipped).
Two-stage unlocking may also be disabled or enabled through the
message center if this is an available message center option or by your
authorized dealer. Refer toMessage centerin theInstrument Cluster

Replacing lost remote entry transmitters
Replacing lost integrated keyhead transmitters (IKTs)
If you would like to have your integrated keyhead transmitters
reprogrammed because you lost one, or would like to buy additional
IKTs, you can either reprogram them yourself, or take all IKTs to your
authorized dealer for reprogramming.
To program a new integrated keyhead transmitter yourself, refer to
SecuriLockpassive anti-theft systemlater in this chapter.Note:At
least two IKTs are required to perform this procedure yourself.
Replacing lost intelligent access (IA) transmitters
If you would like to have additional intelligent access keys programmed
to your vehicle, please contact your authorized dealer.

SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLockpassive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded integrated keyhead transmitter (IKT) or
intelligent access keys programmed to your vehicleis used. The
use of the wrong type of coded key may lead to a “no-start” condition.
The message center will display: NO KEY DETECTED.
If you are unable to start the engine with a correctly coded key, this
indicates a malfunction. The message center will display: STARTING
SYSTEM MALFUNCTION.
Your vehicle comes with two coded integrated keyhead transmitters or
intelligent access keys; additional coded transmitters may be purchased
from your authorized dealer. The authorized dealer can program your
spare transmitters to your vehicle or you can program then yourself.
Refer toProgramming spare integrated keyhead transmittersor
Programming spare intelligent access keysfor instructions on how to
program the coded key.
For integrated keyhead transmitter (IKT), the standard SecuriLock
keys without remote entry transmitter functionality can also be
purchased from your authorized dealer if desired.
Note:The SecuriLockpassive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.
Automatic arming
The vehicle is armed immediately after turning the ignition off.
Automatic disarming
Switching the ignition on with acoded keydisarms the vehicle.
Replacement of integrated keyhead transmitters (IKT) or intelligent
access keys
Note:Your vehicle comes equipped with two integrated keyhead
transmitters (IKTs) or two intelligent access keys.
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 and remote keys can be programmed to your vehicle.
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 eight 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 keycode 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; all 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.
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 ten 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.
6. Turn the ignition off and remove the second previously programmed
coded key from the ignition.
7. After three seconds but within 10 seconds of turning the ignition off
and removing the previously programmed coded key, insert the new
unprogrammed key (new key/valet key) into the ignition.
8. Turn the ignition from off to on. Keep the ignition on for at least six
seconds.
9. Remove the newly programmed coded key from the ignition.
If the key has been successfully programmed it will start the vehicle’s
engine and will operate the remote entry system (if the new key is an
integrated keyhead transmitter).
