2012 JEEP GRAND CHEROKEE key fob battery

A WORD ABOUT YOUR KEYSYour vehicle uses a keyless ignition system.
This system consists of a Key Fob with Remote
Keyless Entry (RKE) transmitter and a Wireless
Ignition Node (WIN) with integral ignition
switch. You can insert the Key Fob into the
ignition switch with either side up.
Keyless Enter-N-Go Feature
This vehicle is equipped with the Keyless Enter-
N-Go feature, refer to “Starting Procedures” in
“Starting And Operating” for further informa-
tion.
Wireless Ignition Node (WIN)The Wireless Ignition Node (WIN) operates
similar to an ignition switch. It has four operat-
ing positions, three of which are detented and
one spring-loaded. The detented positions are
OFF, ACC, and ON/RUN. The START position is
a spring-loaded momentary contact position.
When released from the START position, the
switch automatically returns to the detented
ON/RUN position.NOTE:
With the Keyless Enter-N-Go feature, the
Electronic Vehicle Information Center (EVIC)
will display the ignition switch position
(OFF/ACC/RUN). Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further
information.
Key FobThe Key Fob operates the ignition switch. Insert
the square end of the key fob into the ignition
switch located on the instrument panel and
rotate to the desired position. It also contains
the Remote Keyless Entry (RKE) transmitter
and an emergency key, which stores in the rear
of the Key Fob.
The emergency key allows for entry into the
vehicle on the driver’s side should the battery in
the vehicle or the RKE transmitter go dead. The
emergency key is also for locking the glove
box. You can keep the emergency key with you
when valet parking.
NOTE:
Entering a vehicle using the emergency key
with the theft alarm armed, will result in the
alarm sounding. Insert the Key Fob (even if
the Key Fob battery is dead) into the ignition
switch to disarm theft alarm.
To remove the emergency key, slide the me-
chanical latch at the top of the Key Fob side-
ways with your thumb and then pull the key out
with your other hand.

General InformationThe RKE transmitter and receivers operate on a
carrier frequency of 433.92 MHz as required by
EEC regulations. These devices must be certi-
fied to conform to specific regulations in each
individual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION DIRECTIVE 95/56/EC. Operation is
subject to the following two conditions:
•This device may not cause harmful interfer-
ence. •
This device must accept any interference
received, including interference that may
cause undesired operation.
If your RKE transmitter fails to operate from a
normal distance, check for these two condi-
tions:
1. Weak battery in RKE transmitter. The ex-
pected life of the battery is a minimum of three
years.
2. Closeness to a radio transmitter such as a
radio station tower, airport transmitter, and
some mobile or CB radios.
DOOR LOCKSThe power door locks can be manually locked
from inside the vehicle by using the door lock
knob. To lock each door, push the door lock
knob on each door trim panel downward. To
unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear
doors, pull the door lock knob on the door trim
panel upward. If the lock knob is down when
the door is closed, the door will lock. Therefore,
make sure the key is not inside the vehicle
before closing the door.
WARNING!
• For personal security and safety in the
event of an accident, lock the vehicle doors
when you drive, as well as when you park
and leave the vehicle.
• When leaving the vehicle, always remove
the key fob from the ignition and lock your
vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
