7. Reinsert the emergency key until it locks into place.
NOTE:
The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by
an authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be re-purposed and reprogrammed to
another vehicle.
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.
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 Ú
page 449.
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 addition, if the light begins to flash after the
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

Back Up Starting Method

NOTE:The key fob may not be detected by the
vehicle Keyless Enter-N-Go system if it is
located next to a mobile phone, laptop or
other electronic device; these devices may
block the key fob’s wireless signal and
prevent the Keyless Enter-N-Go system from
starting the vehicle.
For more information on the engine starting
procedure, see Ú page 118.
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be

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
