2008 Mercury Mariner Hybrid ECU

Replacing the battery
The Integrated Keyhead Transmitter uses one coin type three-volt
lithium battery CR2032 or equivalent.
To replace the battery:
1. Twist a thin coin in the slot of the
IKT near the key ring in order to
remove the battery cover.
2. Do not wipe off any grease on the
battery terminals on the back
surface of the circuit board.
3. Remove the old battery.Note:Please refer to local regulations when
disposing of transmitter batteries.
4. Insert the new battery. Refer to the instructions inside the IKT for the
correct orientation of the battery. Press the battery down to ensure that
the battery is fully seated in the battery housing cavity.
5. Snap the battery cover back onto the key.
Note:Replacement of the battery willnotcause the IKT to become
deprogrammed from your vehicle. The IKT should operate normally after
battery replacement.
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 takeall IKTsto your
authorized dealer for reprogramming.
How to reprogram your Integrated Keyhead Transmitters (IKTs)
To program a new Integrated Keyhead Transmitter yourself, refer to
Programming spare keysin theSecuriLockpassive anti-theft
section of this chapter.Note:At least two IKTs are required to perform
this procedure yourself.

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)
programmed to your vehicleis used. The use of the wrong type of
coded key may lead to a “no-start” condition.
Your vehicle comes with two coded Integrated Keyhead Transmitters;
additional coded IKTs may be purchased from your authorized dealer.
Standard SecuriLockkeys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired. The authorized dealer can program your spare IKTs to your
vehicle or you can program the IKTs yourself. Refer toProgramming
spare Integrated Keyhead Transmittersfor instructions on how to
program the coded key.
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 IKT while starting the engine. These
objects will not cause damage to the coded IKT, but may cause a
momentary issue if they are too close to the IKT when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded IKT and restart the engine.

Anti-theft indicator
The anti-theft indicator is located in the instrument panel cluster.
•When the ignition is in the 1
(LOCK) position, the indicator
will flash once every 2 seconds to
indicate the SecuriLocksystem
is functioning as a theft deterrent.
•When the ignition is in the 3 (RUN) position, the indicator will glow
for 3 seconds to indicate normal system functionality.
If a problem occurs with the SecuriLocksystem, the indicator will flash
rapidly or glow steadily when the ignition is in the 3 (RUN) position. If
this occurs, the vehicle will not start and should be taken to an
authorized dealer for service.
Automatic arming
The vehicle is armed immediately after switching the ignition to the 1
(LOCK) position.
The theft indicator will flash every
two seconds to act as a theft
deterrent when the vehicle is
armed.
Automatic disarming
The vehicle is disarmed immediately after the ignition is turned to the 3
(RUN) position.
The theft indicator will illuminate for three seconds and then go out. If
the theft indicator stays on for an extended period of time or flashes
rapidly, have the system serviced by your authorized dealer.
Replacement Integrated Keyless Transmitters (IKT) and coded keys
Note:Your vehicle comes equipped with two Integrated Keyhead
Transmitters (IKTs). The 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 keys can be IKTs
with remote entry functionality.
If your IKTs or standard SecuriLockcoded keys 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 keys
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; 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.
1. Insert the first previously
programmedcoded keyinto the
ignition.
2. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position.
Keep the ignition in the 3 (RUN) position for at least three seconds, but
no more than 10 seconds.
3. Turn the ignition to the 1 (LOCK) position and remove the firstcoded
keyfrom the ignition.
4. Within ten seconds of turning the ignition to the 1 (LOCK) position,
insert the second previouslycoded keyinto the ignition.

5. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position.
Keep the ignition in the 3 (RUN) position for at least three seconds, but
no more than 10 seconds.
6. Turn the ignition to the 1 (LOCK) position and remove the second
previously programmedcoded keyfrom the ignition.
7. Within twenty seconds of turning the ignition to the 1 (LOCK)
position and removing the previously programmedcoded key,insert the
new unprogrammed key (new key/valet key) into the ignition.
8. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position.
Keep the ignition in the 3 (RUN) position for at least six seconds.
9. Remove the newly programmedcoded keyfrom 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). The theft indicator light will illuminate
for three seconds and then go out to indicate successful programming.
If the key was not successfully programmed, it will not start your
vehicle’s engine and/or will not operate the remote entry features. The
theft indicator light may flash on and off. Wait 20 seconds and you may
repeat Steps 1 through 8. If failure repeats, bring your vehicle to your
authorized dealer to have the new key(s) programmed.
To program additional new unprogrammed key(s), wait twenty seconds
and then repeat this procedure from Step 1.
