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, a chime will sound to remind you to remove the
key.
NOTE:The Key-In-Ignition reminder only sounds
when the ignition key is placed in the LOCK or ACC
position.
SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses the factory-mated Fob with Integrated
Key and Wireless Ignition Node (WIN) to prevent unau-
thorized vehicle operation. Therefore, only Fobs that are
programmed to the vehicle can be used to start and
operate the vehicle. The system will shut the engine off in
two (2) seconds if someone uses an invalid Fob to start
the engine.
After turning the ignition switch to the ON position, the
Vehicle Security Alarm Indicator Light will turn on for
three (3) seconds for a bulb check. If the light remains on
after the bulb check, it indicates that there is a problem
with the electronics. In addition, if the light begins to

flash after the bulb check, it indicates that someone used
an invalid Fob to start the engine. Either of these condi-
tions will result in the engine being shut off after two (2)
seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.
NOTE:
²The Sentry Key Immobilizer System is not compatible
with aftermarket remote starting systems. Use of these
systems may result in vehicle starting problems and
loss of security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Fobs, or any
other transponder-equipped components on the same
key chain willnotcause a fault unless the additional
part isphysically held against the Fobbeing used tostart the vehicle. Cell phones, pagers, or other RF
electronics will not cause interference with this system.
All of the Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Fobs that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Fob is programmed to a vehicle, it cannot be
programmed to any other vehicle.
CAUTION!
Always remove Sentry Keys from the vehicle and
lock all doors when leaving the vehicle unattended.
At the time of purchase, the original owner is provided
with a four-digit PIN number. Keep the PIN in a secure

location. This number is required for dealer replacement
of Fobs. Duplication of Fobs may be performed at an
authorized dealer or by using the Customer Key Pro-
gramming procedure. This procedure consists of pro-
gramming a blank Fob to the vehicle electronics. A blank
Fob is one, which has never been programmed.
NOTE: When having the Sentry Key Immobilizer
System serviced, bring all vehicle Fobs with you to the
dealer.
Customer Key (Fob) Programming
If you have two valid sentry keys, you can program new
sentry keys to the system by performing the following
procedure:
1. 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.2. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chime
will sound and the Vehicle Security Alarm Indicator
Light will begin to flash. Turn the ignition switch OFF
and remove the second key.
3. 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 and the Vehicle
Security Alarm Indicator Light will stop flashing, turn on
again for 3 seconds, and then turn off.
The new Sentry Key is programmed.The Keyless Entry
Transmitter will also be programmed during this pro-
cedure.
Repeat this procedure to program up to 8 keys. If you do
not have a programmed sentry key, contact your dealer
for details.
