General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, in- cluding interference that may cause undesired opera-
tion.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
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 a key fob, an Ignition Node Module,
Keyless Push Button Ignition and a 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 will not allow the engine to
crank if an invalid key fob is used to start and operate the
vehicle. The system will shut the engine off in two seconds
if an invalid key fob is used to start the engine.
NOTE: A key fob that has not been programmed is also
considered an invalid key.
During normal operation, after placing the keyless 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 used

an invalid key fob 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 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.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Customer Key Programming
Programming key fobs may be performed at an authorized
dealer.
Replacement Keys
NOTE: Only key fobs that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a key fob is programmed to a vehicle, it cannot be
programmed to any other vehicle.
CAUTION!
• Always remove the key fobs from the vehicle and
lock all doors when leaving the vehicle unattended.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, always remember to place the ignition in
the OFF position.
NOTE: 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.
When having the Sentry Key Immobilizer System serviced,
bring all vehicle keys with you to an authorized dealer.
