immobilizer DODGE CARAVAN 2006 4.G Owners Manual

NOTE:The power window switches, radio, power
outlets, and removable console (if equipped), will remain
active for up to 45 seconds after the ignition switch has
been turned off. Opening a vehicle front door will cancel
this feature.
WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
If you open the driver’s door and the key is in the ignition
switch, a chime will sound to remind you to remove the
key.
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:
•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.
•Exxon/Mobil Speed Pass,™additional Sentry Keys, or
any other transponder equipped components on the
same keychain willnotcause a key-related (transpon-
der) fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Cell phones, pagers, or other RF electronics
will not cause interference with this system.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.Customer Key Programming
You can program new sentry 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.

1. With the transmitter buttons facing down, use a thin
coin to pry the two halves of the transmitter apart. Make
sure not to damage the rubber gasket during removal.2. Remove and replace the batteries. Avoid touching the
new batteries with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To reassemble the transmitter case snap two halves
together. Make sure there is an even“gap”between the
two halves. Test transmitter operation.
VEHICLE THEFT ALARM—IF EQUIPPED
This system monitors the vehicle doors and ignition
switch for unauthorized entry or operation. When the
alarm is activated, the system provides both audible and
visual signals. The horn will pulse, headlights/park
lights will flash, the Vehicle Theft Alarm/Immobilizer
light, located in the instrument cluster, will flash, and the
vehicle will not start. If the alarm is triggered and no
action is taken to disarm it, the system will turn off the
horn after three minutes and after 15 minutes of light
only operation the system will then rearm itself.

26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To arm the system:Remove the key from the ignition
switch and either:
1. Press a power door lock button while the driver’sor
passenger’s door is open.
2. Press the LOCK button on the keyless entry transmit-
ter.
After the last door is closed, or if all doors are closed, the
system will arm itself in about 16 seconds. During that
time, the Vehicle Theft Alarm/Immobilizer light will
flash. If it does not illuminate, the system is not arming.
If you open a door during this arming period, the system
will cancel the arming process. You must repeat one of
the previously described arming sequences to rearm the
system.
To disarm the system:Press the UNLOCK button on the
keyless entry transmitter. Also, using a valid sentry keyand moving the ignition switch to the ON/START posi-
tion will disarm the system. If you disarm the system and
access the liftgate area, the system must be rearmed, as
described previously, when closing the liftgate. If some-
thing has triggered the system in your absence, the horn
will sound three times when you disarm the system.
Check the vehicle for tampering.
NOTE:
•The driver’s door and liftgate key cylinders cannot
arm or disarm the system.
•Once the alarm is set, and the liftgate button on the
keyless entry transmitter is pressed, on a non-power
liftgate vehicle, you have a 30 second one time access
into the liftgate area. If the liftgate is not opened within
30 seconds the liftgate will remain locked.
