Sentry Key - Jeep GRAND CHEROKEE 2023 Owner's Manual

Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
 Once a key fob is programmed to a vehicle, it cannot be
repurposed and reprogrammed to another vehicle.
 Only key fobs that are programmed to the vehicle elec-
tronics can be used to start and operate the vehicle.
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™ Igni-
tion, always remember to place the ignition in the
OFF position when exiting the 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 autho-
rized 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
GETTING TO KNOW YOUR VEHICLE
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.
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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
NOTE:
A key fob that has not been programmed is also
considered an invalid key.
