immobilizer JEEP WRANGLER 2021 Owner handbook (in English)

To Exit Remote Start Mode Without
Driving The Vehicle
Push and release the remote start button one
time or allow the engine to run for the entire
15-minute cycle.
NOTE:
To avoid unintentional shut downs, the sys-
tem will disable the one time push of the
remote start button for two seconds after
receiving a valid remote start request.
To Exit Remote Start Mode And Drive The
Vehicle
Before the end of the 15-minute cycle, push
and release the unlock button on the key fob
to unlock the doors and disarm the vehicle
security alarm (if equipped). Then, insert the
key into the ignition and place the ignition in
the ON/RUN position.
NOTE:
The ignition must be placed in the ON/RUN
position in order to drive the vehicle.
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 key fobs that have an em-
bedded electronic chip (transponder) to pre-
vent unauthorized vehicle operation. There-
fore, only key fobs that are programmed to
the vehicle can be used to start and operate
the vehicle. The system will shut the engine
off in two seconds if someone uses an invalid
key to try to start the engine.
NOTE:
A key fob that has not been programmed is
also considered an invalid key, even if it is cut
to fit the ignition or lock cylinder for that
vehicle.
During normal operation, after placing the
ignition in the on position, the vehicle secu-
rity light will turn on for three seconds for abulb check. If the light remains on after the
bulb check, it indicates that there is a prob-
lem with the electronics. In addition, if the
vehicle security light begins to flash after the
bulb check, it indicates that someone used
an invalid key 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 ten 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
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.GETTING TO KNOW YOUR VEHICLE

Replacement Key Fobs
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 pro-
grammed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the
vehicle and lock all doors when leaving the
vehicle unattended.
Duplication of key fobs may be performed at
an authorized dealer or by following the cus-
tomer key programming procedure. This pro-
cedure 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 key fobs with
you to an authorized dealer.
Customer Key Programming
If you have two valid key fobs, you can pro-
gram new key fobs to the Sentry Key Immo-
bilizer system by performing the following
procedure:
1. Cut the additional key(s) to match the
ignition and lock cylinder key code.
2. Insert the first valid key into the ignition.
Place the ignition in the ON/RUN position
for at least three seconds, but no longer
than 15 seconds. Then, place the ignition
in the LOCK position and remove the first
key.
3. Insert the second valid key into the igni-
tion. Place the ignition in the ON/RUN
position within 15 seconds. After 10 sec-
onds, a chime will sound. In addition, the
Vehicle Security Light will begin to flash.
Place the ignition in the LOCK position
and remove the second key.
4. Insert a blank key into the ignition. Place
the ignition in the ON/RUN position
within 60 seconds. After 10 seconds, asingle chime will sound. In addition, the
Vehicle Security Light will stop flashing.
To indicate that programming is com-
plete, the Vehicle Security Light will turn
on again for three seconds and then turn
off.
The new key is programmed. The key fob
will also be programmed during this pro-
cedure.
Repeat this procedure to program up to eight
keys. If you do not have a programmed key
fob, contact your authorized dealer for de-
tails.
NOTE:
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 from starting your
vehicle. The remaining key fobs must then be
reprogrammed. All vehicle key fobs must be
taken to an authorized dealer at the time of
service to be reprogrammed.
