KEYS
KEY FOB

Your vehicle is equipped with a key fob which
supports Remote Keyless Entry (RKE) (if
equipped) and Keyless Enter-N-Go (if equipped).

If the vehicle is equipped with remote power
door locks, the key fob allows you to lock or
unlock all doors, as well as activate the Panic
Alarm, from distances up to approximately 66 ft
(20 m). The key fob does not need to be pointed
at the vehicle to activate the system.
NOTE:
The key fob’s wireless signal may be blocked
if the key fob is located next to a mobile
phone, laptop, or other electronic device.
This may result in poor performance.
The key fob should not be placed next to the
wireless charging pad (if equipped).
In the ON/RUN position, all key fob buttons
will work until the vehicle reaches 2 mph
(4 km/h).

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.

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 electronics, 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 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.
