2004 DODGE NEON immobilizer

SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized operation of the vehicle by disabling the engine.
The system will shut the engine off after 2 seconds of
running if an invalid key is used to start the vehicle. This
system utilizes ignition keys which have an electronic
chip (transponder) embedded into them. Only keys that
have been programmed to the vehicle can be used to start
and operate the vehicle.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the Theft Alarm/
Immobilizer Light will come on for three (3) seconds
immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a problem with the electronics.
If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (2) seconds of running.Keep in mind that a key which has not been programmed
is also considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation (vehicle has been running for
longer than 10 seconds), a fault has been detected in the
electronics and the vehicle should be serviced as soon as
possible.
NOTE:
²
The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder equipped components on the
same keychain willnot
cause a key-related (tran-
sponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used
when starting the vehicle. Cell phones, pagers, or
other RF electronics will not cause interference with
this system.

All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:
Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it can
not be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure
consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed.
NOTE:When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
dealer.
Sentry Key Programming
You can program new keys to the system if you have two
valid sentry keys by performing the following procedure:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds a chime
will sound and the Theft Alarm Light will begin to flash.
Turn the ignition switch OFF and remove the second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds a single chime will sound. The Theft Alarm Light
will stop flashing, turn on for 3 seconds; then turn off.
The new Sentry Key has been programmed.
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

3. The indicator light in the instrument cluster will flash
rapidly for 16 seconds. This shows that the system is
arming. During this period, if a door is opened, the
ignition switch is turned on, or the power door locks are
unlocked in any manner, the system will automatically
disarm. If the light comes on but does not flash, the
system is arming but there is a problem in the trunk
circuit. After 16 seconds the indicator light will flash
slowly. This shows that the system is fully armed.
Vehicles equipped with the Sentry Key Immobilizer
System can be safely started with a valid key. A valid key
is one that is programmed to that particular vehicle. A
valid key will disarm the system, an invalid key will
trigger the alarm.
To disarm the system:
Unlock a front door using either the key or the Keyless
Entry Transmitter.
Starting the vehicle with a valid Sentry key will disarm
the system.
Tamper Alert
If the horn sounds 3 times when you unlock a front door
using either a key or the Keyless Entry Transmitter, the
alarm has been activated. Check the vehicle for tamper-
ing.
Security System Manual Override
The system will not arm if you lock the doors using the
manual lock control.
REMOTE TRUNK LID RELEASE Ð IF EQUIPPED
You can open the trunk from inside the vehicle by
pressing a switch located inside the glove compartment.
NOTE:The remote trunk release feature will operate
with the ignition switch in all positions. The remote trunk
release will not operate above 5 mph.

WARNING!
Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
During cold weather when temperatures are below
freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump starting because
the battery could rupture or explode. The battery
temperature must be brought up above freezing
point before attempting to jump start.
6. If the vehicle is equipped with sentry key immobilizer,
turn the ignition switch to the ON/RUN position for 3
seconds prior to moving the ignition switch to the crank
position and starting the vehicle.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
8. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting
out the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels, particularly with high output engines.
