KEYS
Key Fob
Your vehicle uses a keyless ignition system. The ignition
system consists of a key fob with Remote Keyless Entry
(RKE) and a START/STOP push button ignition system. The
Remote Keyless Entry system consists of a key fob and
Keyless Enter-N-Go feature.
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 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 handheld key fob. The key fob does not need to be pointed
at the vehicle to activate the system.
NOTE:
• In the ON/RUN position, all key fob buttons will workuntil the vehicle reaches 3 mph (5 km/h).
• The key fob should not be placed next to the wireless charging pad (if equipped). Key Fob
In case the ignition switch does not change with the push of
a button, the key fob may have a low or fully depleted
battery. A low key fob battery can be verified by referring to
the instrument cluster, which will display directions to

• Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children should
be warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the key fob in or near the vehicle, or in alocation accessible to children, and do not leave the

Do NOT Grab The Door Handle When Locking
NOTE:
• After pushing the door handle lock button, you must wait two seconds before you can lock or unlock the doors, using
either Passive Entry door handle. This is done to allow you
to check if the vehicle is locked by pulling the door handle,
without the vehicle reacting and unlocking.
• The Passive Entry system depends on a key fob that is not fully discharged of its coin battery capacity.
• The LED light on the key fob will not blink if the key fob battery is low or fully depleted, but a low key fob battery
condition will still support the Passive Entry system func -tionality. When the key fob battery is low, the instrument
cluster will display a message indicating that the key fob
battery is low. Refer to “Keys” in “Getting To Know Your
Vehicle” for further information.
The vehicle doors can also be locked by using the key fob
lock button or the lock button located on the vehicle’s inte -
rior door panel.

any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
