The Saturn Security System provides both an anti-theft feature, and a fuel
injector disable feature for your Saturn.
You will have the ability to lock and unlock your doors, release your trunk
(sedan), or unlock the liftgate (wagon) when approaching or leaving your
Saturn from a distance of up to 32 ft. (10 m) using your key chain remote
transmit supplied with the Saturn Security System.
Additional features of the Saturn Security System include active security
system arming, programmable passive security system arming, and illuminated
The Saturn Security System consists of a receiver, which is located in your
Saturn, and two transmitters. The receiver can be programmed with up to four
transmitters. Additional transmitters can be purchased at your Saturn

Modes of Operation
You can program the Saturn Security System to be in the active arming mode,
passive arming mode or security system disabled mode.
Active arming of the Saturn Security System requires you to press the "LOCK"
button on your transmitter in order to arm the system. Your Saturn was set
to the active arming mode when it was manufactured.
Passive arming of the Saturn Security System does not require you to press
the "LOCK" button to arm the system. The system will arm itself 5 minutes
after you turn the ignition key to the "LOCK" position and open and close
the car door. However, you may press the "LOCK" button on the transmitter to
arm the system right away instead of waiting for the system to arm itself.
It is not possible to have more than one mode turned on at the same time.
Here's how to change your Saturn Security System mode of operation:
To begin, turn the ignition key to the "RUN" or "ACC" position. Then press
the Panic Alert button (horn symbol) on the transmitter four times within 5
seconds. You now have 3 seconds to select one of the following modes of
. For the active arming mode, press the "LOCK" button on the transmitter.
. For the passive arming mode, press the Trunk/Liftgate Release button
(trunk/liftgate ajar symbol) on the transmitter.
. To disable the security system, press the "UNLOCK" button on the
The chime will sound once when you have selected a mode. The following
sections will explain how both arming modes work.
Active Arming of the Saturn Security System
"LOCK" (Saturn Security System Arms)
You must press the "LOCK" button on your key chain transmitter in order to
arm the Saturn Security System. When you press the "LOCK" button on your
transmitter, all doors will lock, the Saturn Security System will arm
automatically, and the Daytime Running Lamps will flash once. If you press
the "LOCK" button again within 5 seconds after the first press, the horn
will chirp to let you know that the Saturn Security System has armed.
If a door is open when you press the "LOCK" button, the chime will sound
three times, the doors will not lock, and the Saturn Security System will
not arm until all the doors are closed. Once the doors are closed, the
Saturn Security System will arm and the "SECURITY" light will flash to let
you know the system is armed. The horn will not chirp even after all the
doors are closed. To get the horn to chirp if a door was open during the
arming process, you must press the "LOCK" button on your transmitter twice
after the doors are closed.
"UNLOCK" (Saturn Security System Disarms)
When you press the "UNLOCK" button on your transmitter once, the driver side
door will unlock, the Saturn Security System will disarm, and the dome lamp
will come on.
If you press the "UNLOCK" button again within 5 seconds of the first press,
the rest of the doors will unlock.
Passive Arming of the Saturn Security System
When the Saturn Security System on your car is set to the passive arming
mode, the system will arm itself 5 minutes after you turn the ignition key
to the "LOCK" position and open and close the car door. (For example, when
you stop your car, turn the ignition key to the "LOCK" position, remove the
key and exit the car.) Immediately after you close the door, the security
system clock will begin to count down, and after 5 minutes have passed, the
Saturn Security System will arm itself.
When in the passive arming mode, the doors will not lock automatically. You
must press the interior door lock switch or use your key to lock the door.
Unlock (Saturn Security System Disarms)
You must press the "UNLOCK" button on the transmitter to disarm the security
system. If you unlock your door using the key without pressing the "UNLOCK"
button on the transmitter, the alarm will be activated. If the alarm
activates, you can press any button on the transmitter to stop the alarm.
When you press the "UNLOCK" button on your transmitter, the doors will
If you hear three horn chirps when you press the "UNLOCK" or "LOCK" button
on your transmitter, that means your Saturn's alarm was triggered while you
Trunk (Liftgate) Release
The trunk (or liftgate) will unlock when the car symbol button is pressed on
the transmitter with the ignition off or when your Saturn is not moving. For
safety reasons, you cannot open your trunk or liftgate using the car symbol
button on your transmitter when your Saturn is moving.
The horn will sound and the headlamps will flash when you press the red horn
symbol button on the transmitter. This panic alarm will continue for 2
minutes, or until you press the red horn symbol button again, whichever
The dome lamp must be in the "DOOR" position for the illuminated entry
feature to work. When you press the "UNLOCK" 'button on your transmitter,
the dome lamp will come on and stay on for 20 seconds or until a door is
opened. After the door is opened, the dome lamp will remain on as long as
the door is open. Once you close the door, the dome lamp will stay on for 20
seconds or until you put your key into the ignition and turn the key to the
This feature will allow you to see inside your car before you open the door,
and will allow extra time with the dome lamp on once you get inside your
The Saturn Security System can keep your Saturn's battery from running down
if a door is left open or ajar with the dome lamp switch in the "DOOR"
position. If the ignition is turned to the "LOCK" position, the ignition key
is removed, and a door is left open or ajar, the dome lamp will turn off in
20 minutes. The Saturn Security System will turn the dome lamp off if the
dome lamp switch is in the "ON" position.
Starting Your Saturn (If your transmitter is lost or damaged and the Saturn
Security System is armed.)
. Use your key to unlock and open the door. The alarm will start a
pre-alarm horn chirp.
. Immediately place your key in the ignition and start the vehicle. This
will cancel the alarm and disarm the Saturn Security System.
If you have not misplaced your transmitter, but it is not working properly,
see "Synchronization." If your transmitter is still not working properly
after you have gone through the synchronization procedure, follow the steps
above and see your Saturn retailer for service.
Synchronization is the method used to keep the transmitter of the vehicle
communicating with the receiver of the vehicle. Synchronization may be
required due to the security method used by this system. The transmitter
does not send the same signal twice. The receiver will not accept a signal
that has been sent to it more than once. This eliminates the possibility
that the signal will be recorded and played back.
Your Saturn vehicle has an automatic synchronization function built into the
system. In some cases a manual synchronization may need to be performed for
proper operation of your transmitters. If your transmitter is inoperative,
perform the manual synchronization as described in this section.
To manually synchronize your transmitter with the receiver, press and hold
the "LOCK" and "UNLOCK" buttons on the transmitter at the same time for
about 7 seconds while you are near your Saturn. The horn will chirp once and
the dome lamp will flash once. The door locks will unlock or lock, depending
on their starting position. If the horn does not chirp or the door locks do
not unlock or lock, see your Saturn retailer for service.
Transmitter and Receiver Range
The range of the Saturn Security System should be about 32 feet (10 m). You
may notice a decrease in range at times, and this should be considered
normal for any security system.
If your transmitter does not work, or if you are having to stand closer than
normal to your Saturn for the transmitter to work, consider the following:
. You may have to replace your transmitter battery. See the next part,
"Battery Replacement," for more information.
. You may have to synchronize your transmitter with your receiver. See
"Synchronization" for more information.
. You may be too far from your Saturn. Check your distance from the car.
. You may be in a crowded parking lot and other cars are blocking the
signal. Take a few steps in either direction and try again.
. You may be experiencing radio frequency interference (RFI). RFI is caused
by close proximity to radio broadcast stations, electric motors, heaters,
alarm systems, and other frequencies that distort the Saturn Security System
transmission frequency. Check for these items near your location.
. You may have to stand closer to your Saturn in rain, snow, and in very
high and low temperatures.
. Your transmitter may work better if you hold it vertically or
horizontally, depending where you are around your Saturn.
. You may notice that just taking one step to the right or left makes the
transmitter work. This is due to your Saturn's body frame structure.
If none of the above apply, see your Saturn retailer or authorized service
provider for service.
Under normal use, the battery in your key chain transmitter should last
about two years. You can tell if the battery is weak if the transmitter
won't work at the normal range in any location. If you have to get close to
your vehicle before the transmitter works, it's probably time to change the
For battery replacement, use a Panasonic battery, 3 volt, type CR2032, or
its equivalent. To replace the battery, follow these steps:
1. Use a small coin or a flathead screwdriver to separate the bottom of the
transmitter from the top.
2. Remove the battery and replace with a Panasonic CR2032, or its
When removing or replacing the battery, use care not to touch any of the
circuitry. Static from your body transferred to these surfaces may damage
3. Make sure the positive (+) side of the battery faces away from the
4. Snap the top and bottom sides of the transmitter together.
5. Test the transmitter with your Saturn to see if it is working correctly.
If the transmitter does not work, try synchronizing your transmitter with
your receiver. See "Synchronization" for more information.
Matching Transmitter(s) to Your Saturn
Each transmitter is coded to prevent another transmitter from activating the
Saturn Security System in your Saturn. If a transmitter is lost or stolen, a
replacement can be purchased at your Saturn retailer.
Remember to bring any remaining transmitters with you when you go to your
retailer. When the retailer matches the replacement transmitter to your
vehicle, any remaining transmitters must also be matched.
Once your retailer has coded the new transmitter, the lost transmitter will
not unlock your vehicle. Each vehicle can have only four transmitters
matched to it.
Your Saturn Security System also enables you to turn the alarm system and
the horn chirp on or off, depending on your needs. To program either or both
of these features, contact your Saturn retailer for assistance.
You can program a transmitter to as many different 2001 L-Series Saturn cars
as you own, as long as they have the power door lock option. Each Saturn can
use up to four transmitters.
Programming a Receiver with a New Transmitter
Because this operation can be difficult, we suggest you refer to the 2001
Saturn L-Series Body/Electrical Volume H Service Manual, or contact your
Saturn retailer for assistance.
