Jeep 2015 Cherokee - Owner Manual - Manual (Page 19)

The system uses a Key Fob with a factory-mated Remote
Keyless Entry (RKE) transmitter, a Keyless Ignition Node
(KIN) and a RF receiver to prevent unauthorized vehicle
operation. Therefore, only Key Fobs that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will not allow the engine to crank
with an invalid Key Fob.
After placing the ignition to 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 system. In
addition, if the light begins to flash after the bulb check,
it indicates that someone used an invalid Key Fob 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 system.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.
CAUTION!
• Do not make modifications or alterations to the
immobilizer system. Modifications or alterations to
the immobilization system may result in a loss of
security protection.
• The Sentry Key® Immobilizer system is not com-
patible with some aftermarket remote starting sys-
tems. Use of these systems may result in vehicle
starting problems and loss of security protection.
