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.
Emergency Key Removal
20 GETTING TO KNOW YOUR VEHICLE

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 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, tailgate, and the RamBox (if equipped) 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, the tailgate and the RamBox
(if equipped). The turn signal lights will flash and the horn
will chirp to acknowledge the signal.

Air Suspension (Remote Lowering Of The Vehicle)
— If Equipped
For easy entry and loading, your vehicle can be
lowered by pushing the key fob air suspension
lowering button two times. When key fob low-
ering is requested, the vehicle will send a series
of chirps and flashes to alert the customer that the opera-
tion has begun and will continue these alerts until it
successfully lowers.
The following conditions must be met for the vehicle to
lower remotely:
• The vehicle must not already be in Entry/Exit (Park)
ride height.
• The vehicle battery must be fully charged.
• All doors must be closed.
• The key fob must be out of the vehicle. Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime. When vehicle
lowering is canceled, the vehicle will raise up to the next
defined level and lock out the remote lowering feature
until the ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob air suspension
lowering button one time during the lowering process.
When vehicle lowering is canceled, the horn will chirp two
times and the turn signal lamps will flash four times. Once
raising is completed, the horn will chirp one time.
NOTE:
Refer to “Air Suspension System” in “Starting And
Operating” for further information.
Replacing The Battery In The Key Fob With Remote
Control
The recommended replacement battery is one CR2032
