GETTING TO KNOW YOUR VEHICLE 29
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 RF rec
eiver 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 turning the ignition switch to the ON/RUN position,
the veh
icle 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
i
nvalid
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
operati
on (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 pr
ogrammed to the vehicle electronics.
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!
The Sentry Key Immobilizer system is not compatible
with som
e aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
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.
