2015 Ram 1500 Immobilizer

A WORD ABOUT YOUR KEYS
Your vehicle uses either a key start ignition system or
keyless ignition system. The key start ignition system
consists of a either a bladed key with an immobilizer chip
in it, or a Key Fob with Remote Keyless Entry (RKE)
transmitter and an Ignition Node Module (IGNM). The
keyless ignition system consists of a Key Fob with
Remote Keyless Entry (RKE) transmitter and a Keyless
Ignition Node (KIN).
Ignition Node Module (IGNM)
The Ignition Node Module (IGNM) 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 contact position. When
released from the START position, the switch automati-
cally returns to the ON/RUN position.

12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Key-In-Ignition Reminder
Opening the driver’s door when the Key Fob is in the
ignition and the ignition switch position is OFF or ACC,
a chime will sound to remind you to remove the Key Fob.
NOTE:
•#Keyed#Ignition systems will chime in OFF or ACC
when the driver door is open.
•“Keyless#Ignition systems will chime in ACC or RUN
when the driver door is open.
•If equipped with Electronic Vehicle Information Center
(EVIC)/Driver Information Display (DID), the EVIC
will display “Key In Ignition”.
SENTRY KEY®
The Sentry Key® Immobilizer System prevents unau-
thorized 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 with a factory-mated Remote
Keyless Entry (RKE) transmitter, an Ignition Node Mod-
ule, Keyless Ignition Node (KIN) and a 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 will not allow
the engine to crank if an invalid Key Fob is used to start
and operate the vehicle. The system will shut the engine
off in two seconds if an invalid Key Fob is used to start
the engine.
NOTE:A Key Fob that has not been programmed is also
considered an invalid key.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

During normal operation, after turning on the ignition
switch, 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 used an invalid
Key Fob to try to start the engine. Either of these
conditions will result in the engine being 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 electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.
CAUTION!
The Sentry Key® Immobilizer system is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

CAUTION!
•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™,
always remember to place the ignition in the OFF
position.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of Key Fobs.
Duplication of Key Fobs may be performed at an autho-
rized 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 Sys-
tem serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
