2016 JEEP GRAND CHEROKEE immobilizer

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 RKE Key Fob, an Ignition Node
Module, Keyless Push Button Ignition and a RF receiver
to prevent unauthorized vehicle operation. Therefore,
only RKE 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 RKE Key
Fob is used to start and operate the vehicle. The system
will shut the engine off in two seconds if an invalid RKE
Key Fob is used to start the engine.
NOTE:A RKE Key Fob that has not been programmed is
also considered an invalid key. During normal operation, after placing the keyless igni-
tion 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 used an invalid RKE 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.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 RKE Key Fobs provided with your new vehicle
have been programmed to the vehicle electronics.
Replacement RKE Key Fobs
NOTE: Only RKE Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a RKE Key Fob is programmed to a vehicle,
it cannot be programmed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
• For vehicles equipped with Keyless Enter-N-Go,
always remember to place the ignition in the OFF
position.
NOTE: Duplication of RKE Key Fobs may be performed
at an authorized dealer. This procedure consists of pro-
gramming a blank RKE Key Fob to the vehicle electron-
ics. A blank RKE Key Fob is one that has never been
programmed.
When having the Sentry Key Immobilizer System ser-
viced, bring all vehicle keys with you to an authorized
dealer.2
