If the vehicle is unlocked by key fob, and no
door is opened within 60 seconds, the ve-
hicle will re-lock and if equipped, the secu-
rity alarm will arm. To change the current

Programming Additional Key Fobs
Programming the key fob may be performed
by your authorized dealer.
Request For Additional Key Fobs
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 pro-
grammed to a vehicle, it cannot be pro-
grammed to any other vehicle.
WARNING!
• Always remove the key fobs from the
vehicle and lock all doors when leaving
the vehicle unattended.
• Always remember to place the ignition in
the OFF mode.
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.
NOTE:
Black keys (6.4L) must be replaced with

ignition switch with the push of a button as
long as the key fob is in the passenger com-
partment.

Vehicle On Message
When opening the driver's door when the
ignition is in RUN (engine not running), a
chime will sound to remind you to place the
ignition in the OFF position. In addition to
the chime, the message will display “Ignition
Or Accessory On” in the cluster.
NOTE:
The power window switches and power sun-
roof (if equipped) will remain active up to ten
minutes after the ignition is cycled to the OFF
position. Opening either front door will can-
cel this feature. The time for this feature is
programmable.
WARNING!
• Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK, apply the
parking brake, place the engine in the
OFF position, remove the key fob from
the vehicle and lock your vehicle. If

the vehicle and lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.

oxide is poisonous and can cause seri-
ous injury or death when inhaled.
• Keep key fobs away from children. Op-
eration of the Remote Start System,
windows, door locks or other controls
could cause serious injury or death.
