Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition
sounds a signal 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 unauthor-
ized 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 ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized ve-
hicle operation. Therefore, only keys that are programmed
to the vehicle can be used to start and operate the vehicle.
The system will shut the engine off in two seconds if
someone uses an invalid key to try to start the engine. NOTE: A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
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 Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!The Sentry Key  Immobilizer system is not compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key  is programmed to a vehicle, it cannot
be programmed to any other vehicle. CAUTION!Always remove the 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 Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of keys. Du-
plication of keys may be performed at an authorized
dealer or by following the customer key programming
procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key is one
that has never been programmed.
NOTE: When having the Sentry Key  Immobilizer Sys-
tem serviced, bring all vehicle keys with you to an
authorized dealer. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17
