2012 RAM CHASSIS CAB immobilizer

WARNING! (Continued)• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!An unlocked car is an invitation to thieves. Always
remove the key from the ignition and lock all doors
when leaving the vehicle unattended.
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:
• The Key-In-Ignition reminder only sounds when the
Key Fob is placed in the OFF or ACC ignition position. • If equipped with Electronic Vehicle Information Cen-
ter (EVIC) the EVIC will display “Key In Ignition”.
SENTRY KEY 
The Sentry Key  Immobilizer System prevents unauthor-
ized 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 and Wireless Ignition
Node (WIN) 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.16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE: A Key Fob that has not been programmed is also
considered an invalid key.
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 sec-
onds), 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. CAUTION!The Sentry Key  Immobilizer system is not compat-
ible with some after-market 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.
2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

CAUTION!Always remove the Sentry Keys  from the vehicle
and lock all doors when leaving the vehicle unat-
tended.
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 System
serviced, bring all vehicle keys with you to an autho-
rized dealer. • If a programmed Key Fob is lost, see your authorized
dealer to have all remaining Key Fobs erased from the
system’s memory. This will prevent the lost Key Fobs
from starting your vehicle. The remaining Keys Fobs
must then be reprogrammed.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
