To remove the emergency key, slide the me-
chanical 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 la-
beled and will illuminate when in position.
The three positions are OFF, ACC, and ON/
RUN. The fourth position is START, during
start RUN will illuminate. 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 emer-
gency key with you when valet parking.
To remove the emergency key, slide the me-
chanical 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 emergency
key) of the key fob against the ENGINE
START/STOP button and push to disarm
the security system.
• 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, tailgate, and the
RamBox (if equipped) as well as activate the
Panic Alarm from distances up to approxi-
mately 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, the tailgate and
the RamBox (if equipped). The turn signal
lights will flash and the horn will chirp to
acknowledge the signal.
NOTE:
Inserting the key fob with integrated key into
the ignition switch disables the system from
responding to any button pushes from that
key fob. Driving at speeds 5 mph (8 km/h)
and above disables the system from respond-
ing to all key fob buttons for all key fobs.

IGNITION SWITCH
Wireless Ignition Node (WIN) —
If Equipped
The Wireless Ignition Node (WIN) operates
similar to an ignition switch. It has four
operating positions, three with detents and
one that is spring-loaded. The detent posi-
tions are OFF, ACC, and ON/RUN. The START
position is a spring-loaded momentary con-
tact position. When released from the START

beled and will illuminate when in position.The three positions are OFF, ACC, and ON/
RUN. The fourth position is START, during
start RUN will illuminate.
NOTE:
In case the ignition switch does not change
with the push of a button, the key fob may
have a low or dead battery. In this situation, a
back up method can be used to operate the
ignition switch. Put the nose side (side oppo-
site of the emergency key) of the key fob
against the ENGINE START/STOP button,
with your foot applied on the brake pedal, and
push to operate the ignition switch.

(refer to "Starting The Engine" in "Starting
And Operating" for further information).
• For vehicles equipped with Keyless Enter-N-Go — Ignition, make sure the

Vehicle" for further information).
• Push the lock button on the key fob.
3. If any doors are open, close them.
The vehicle security alarm will set when you
use the power door locks, or use the key fob to
lock the doors. After all the doors are locked
and closed, the vehicle security light, in the
instrument panel cluster, will flash rapidly for
about 16 seconds to indicate that the alarm

using any of the following methods:
1. Push the unlock button on the key fob.
2. Grasp the Passive Entry Unlock Door Handle with a valid key fob within 5 ft

— Passive Entry" in "Getting To Know Your
Vehicle" for further information.
3. Cycle the ignition out of the OFF position.
• For vehicles equipped with KeylessEnter-N-Go — Ignition, push the Key-

quires at least one valid key fob in the
vehicle).
• For vehicles not equipped with Keyless Enter-N-Go, insert a valid key into the
ignition switch and turn the key to the
ON position.
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.
