18 GETTING TO KNOW YOUR VEHICLE
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has never
been programmed.
NOTE:

When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.

Keys must be ordered to the correct key cut to
match the vehicle locks.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized 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 a key fob, either a keyless push
button ignition or wireless ignition node system,
and a Radio Frequency (RF) receiver to prevent
unauthorized vehicle operation. Therefore, only
key fobs that are programmed to the vehicle can
be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition in the ON/RUN position,
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 light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
If the Vehicle Security 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
serviced as soon as possible by an authorized
dealer.
All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics

The Ignition Node Module (IGNM) operates similar
to an ignition switch. It has four operating
positions, three with detents and one that is
spring-loaded. The detent positions are OFF, ACC,
and ON/RUN. The START position is a
spring-loaded momentary contact position. When
released from the START position, the switch
automatically returns to the ON/RUN position.
