2023 RAM CHASSIS CAB immobilizer

18GETTING TO KNOW YOUR 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.
Keys must be ordered to the correct key cut to
match the vehicle locks.
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 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. In addition, if the light
begins to flash after the bulb check, it indicates
that someone 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.
All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú
page 427.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button as long as
the Remote Keyless Entry 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 illuminate.
NOTE:In case the ignition switch does not change with
the push of a button, the key fob may have a low or
depleted battery. In this situation, a backup
method can be used to operate the ignition switch.
Put the nose side (side opposite of the emergency
key) of the key fob against the START/STOP
ignition button, with your foot applied on the brake
pedal, and push to operate the ignition switch.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
For vehicles equipped with Keyless
Enter ‘n Go™ Ignition, always remember to
place the ignition in the OFF position when
exiting the vehicle.
CAUTION!

The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting
problems and loss of security protection.
