The valet key fits only the ignition switch and driver’s
door lock. You can keep the trunk and glove box
locked when you leave your vehicle and valet key at a
parking facility.
Do not attach a large key holder or key case to
either key. If it banged against your knees while
you were driving, it could turn the ignitionswitch from the ON position to the ACC or OFF
position, thereby stopping the engine.
„ Key number
The key number is stamped on the metal plate at-
tached to the key set. Write down the key number and
keep it in another safe place, not in the vehicle. This
number is needed to make a replacement key if you
lose your key or lock it inside the vehicle.
Immobilizer (WRX-STi)
The immobilizer system is designed to prevent an un-
authorized person from starting the engine. Only keys
registered with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if an unregis-
tered key fits into the ignition switch and can be turned
to the “START” position, the engine will automatically
stop after several seconds.
Each immobilizer key contains a transponder in which
the key’s ID code is stored. When a key is inserted into
the ignition switch and turned to the “ON” position, the
transponder transmits the key’s ID code to the immo-
bilizer system’s receiver. If the transmitted ID code
matches the ID code registered in the immobilizer sys-
tem, the system allows the engine to be started. Since
the ID code is transmitted and acted upon almost in-
stantly, the immobilizer system does not impede nor-
mal starting of the engine.
If the engine fails to start, pull out the key once before
trying again. (Refer to the “Ignition switch” section
[chapter 3].)
NOTE
To protect your vehicle from theft, please pay
close attention to the following security precau-tions:

Remote keyless entry system
Two transmitters are provided for your vehicle.
The remote keyless entry system has the following
functions. yLocking and unlocking the doors (and rear gate on
the Wagon) without a key y Sounding a panic alarm
y Arming and disarming the security system (if your
vehicle is equipped with an optional security system).
See the next section “Security system (if equipped)”
for detailed information.
This device complies with Part 15 of the FCC
Rules and with RSS-210 of Industry Canada. Oper-
ation is subject to the following two conditions: (1)
This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved
by the party responsible for compliance could
void the user’s authority to operate the equipment.
The operable distance of the keyless entry system is
approximately 30 feet (10 meters). However, this dis-
tance will vary depending on environmental condi- tions. The system’s operable distance will be shorter
in areas near a facility or electronic equipment emitting
strong radio waves such as a power plant, broadcast
station, TV tower, or remote controller of home elec-
tronic appliances.
The remote keyless entry system does not operate
when the key is inserted in the ignition switch to pre-
vent accidental lockout.
y
Do not expose the transmitter to severe
shocks, such as those experienced as a result
of dropping or throwing. y Do not take the transmitter apart except when
replacing the battery. y Do not get the transmitter wet. If it gets wet,

audible signal when the doors lock and unlock. If de-
sired, you may turn the audible signal off.
To turn the audible signal off, unlock the door by
pressing the “ ” button and then simultaneously
depress “ ” and “ ” buttons for more than two
seconds. An electronic chirp will sound twice and the
turn signal lights will flash twice to inform you that the
audible signal has been turned off.

3. Press and release any button on the transmitter
that you wish to program into the system. The horn will
sound twice to indicate that the transmitter has been
programmed.
Any additional transmitters can also be programmed
at this time. Repeat steps 1 through 3 for an additional
transmitter.
To exit the programming mode:
1. After all of your transmitters are programmed, re-
move the key from the ignition switch.
The horn will sound three times to indicate that the
system has exited the programming mode.
2. Make sure that the keyless entry system properly
operates by operating each transmitter. T
Deleting old transmitter codes
The control unit of the keyless entry system has four
memory locations to store transmitter codes, giving it
the ability to operate with up to four transmitters. When
you lose a transmitter, the lost transmitter’s code re-
mains in the memory. For security reasons, lost trans-
mitter codes should be deleted from the memory.
To delete old transmitter codes, program four trans-mitter codes into the system. If you have only one cur-
rent transmitter, program it four times. If you have two
current transmitters, program each one twice. If you
have three current transmitters, program two of them
once and the third one twice. This process will leave
only current transmitter codes in the system’s memo-ry.
NOTE
Make sure no one else is operating their keyless
entry system within range of your vehicle when
programming transmitters. If someone else were
to operate their remote transmitter while you are
programming your transmitters, it is possible that
their transmitter code will be programmed into
your system, allowing them unauthorized access
to your vehicle.

Security system (if equipped)
The security system helps to protect your vehicle and
valuables from theft. The horn sounds and the turn
signal lights flash if someone attempts to break into
your vehicle. The starter motor is also interrupted to
prevent starting the vehicle without a key.
The system can be armed and disarmed with the re-
mote transmitter.
The system does not operate when the key is inserted
into the ignition switch. „System operation
The security system will give the following alarm indi-
cations when triggered: y The turn signal lights will flash and the horn will
sound intermittently. In addition, the starter motor will
not operate. y The alarm automatically resets after 30 seconds;
however, the alarm will reactivate if the vehicle is tam-
pered with again. The alarm will continue for six times
if any sensor continues to be activated.
The alarm is triggered by: y Opening a door, the rear gate or trunk lid.
y Application of physical shock to the vehicle (e.g. forced entry). Note that there are two alarm levels for
shock: warning and alarm. In warning mode, the alarm
detects lower level vibrations and triggers 2 warning
chirps on the horn and two flashes on the lights as a
deterrent to would be vandals. In alarm mode, higher
levels of shock are detected and the system will go into full alarm. y
