GETTING TO KNOW YOUR VEHICLE 31
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, keyless push button ignition 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 switch 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 addi-
tion, if the light begins to flash after the bulb check, it indi -
cates 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 elec -
tronics, 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 ten 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.
Key Programming
Programming key fobs may be performed at 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.

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.
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.
