KEYS
Key Fobs
Your vehicle uses either a wireless ignition node system or
keyless ignition system. The ignition system consists of a
key fob with a Remote Keyless Entry (RKE) and an ignition
switch. The keyless ignition system consists of a key fob
and Keyless Enter-N-Go button.
NOTE:The key fob may not be found if it is located next to
a mobile phone, laptop or other electronic device; these
devices may block the key fob’s wireless signal.
The key fob operates the ignition switch. Insert the square
end of the key fob into the ignition switch located on the
instrument panel and rotate to the desired position. It also
contains the key fob and an emergency key, which stores in
the rear of the key fob.
The emergency key allows for entry into the vehicle should
the battery in the vehicle or the key fob go dead. You can
keep the emergency key with you when valet parking.
To remove the emergency key, slide the mechanical latch at
the top of the key fob sideways with your thumb and then
pull the key out with your other hand. NOTE:
When using the emergency key to gain access to
your vehicle, be aware that the security alarm may be
triggered. Insert the key into the ignition and place the
ignition in the ON/RUN mode to disarm the security
system.
This Keyless Push Button Ignition key fob allows the driver
to operate the ignition switch with the push of a button, as
long as the key fob is in the passenger compartment. The
Keyless Push Button Ignition has four operating positions,
three of which are labeled and will illuminate when in
position. The three positions are OFF, ACC, and ON/RUN.

The fourth position is START, during start RUN will

key, which stores in the rear of the key fob.
The emergency key allows for entry into the vehicle should
the battery in the vehicle or the key fob go dead. You can
keep the emergency key with you when valet parking.
To remove the emergency key, slide the mechanical latch
on the backside of the key fob sideways with your thumb
and then pull the key out with your other hand.
NOTE:When using the emergency key to gain access to
your vehicle, be aware that the security alarm may be
triggered. Put the nose side (side opposite of the emer-
gency key) of the key fob against the ENGINE START/
STOP button and push to disarm the security system. NOTE:
You can insert the double-sided emergency key
into the door lock cylinder with either side up.
The Remote Keyless Entry system allows you to lock or
unlock all doors, and the tailgate as well as activate the
Panic Alarm from distances up to approximately 66 ft (20
m) using a key fob with integrated key. The key fob does
not need to be pointed at the vehicle to activate the system.
Push and release the lock button on the key fob to lock all
doors, and the tailgate. The turn signal lights will flash and
the horn will chirp to acknowledge the signal.

The vehicle security alarm is designed to protect your
vehicle. However, you can create conditions where the
system will give you a false alarm. If one of the previously
described arming sequences has occurred, the vehicle
security alarm will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle and open a
door, the alarm will sound. If this occurs, disarm the
vehicle security alarm.
If the vehicle security alarm is armed and the battery
becomes disconnected, the vehicle security alarm will
remain armed when the battery is reconnected; the exterior
lights will flash, and the horn will sound. If this occurs,
disarm the vehicle security alarm.Rearming Of The System
The vehicle security alarm will rearm itself after the 15
additional minutes of headlights and vehicle security light
flashing, if the system has not been disabled. If the condi-
tion which initiated the alarm is still present, the system
will ignore that condition and monitor the remaining doors
and ignition.
Security System Manual Override
The vehicle security alarm will not arm if you lock the
doors using the manual door lock plunger.
