2023 NISSAN SENTRA change key battery

In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For information regarding replacement of
a battery, see “Battery replacement”
(P. 8-23).
As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent Key:
• Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with wa-
ter or salt water. This could affect the
system function.
• Do not drop the Intelligent Key.
• Do not strike the Intelligent Key
sharply against another object.
• Do not change or modif y the Intelli-
gent Key.
• Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is com-
pletely dry.
• Do not place the Intelligent Key for an
extended period in an area where
temperatures exceed 140°F (60°C).
• Do not attach the Intelligent Key with
a key holder that contains a magnet.
• Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment
and personal computers. If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that
Intelligent Key from the vehicle. This may
prevent the unauthorized use of the Intelli-
gent Key to operate the vehicle. For infor-
mation regarding the erasing procedure, it
is recommended that you visit a NISSAN
dealer.
3-8Pre-driving checks and adjustments

OPERATING RANGE
The Intelligent Key functions can only be
used when the Intelligent Key is within the
specified operating range.
When the Intelligent Key battery is almost
discharged or strong radio waves are pres-
ent near the operating location, the Intelli-
gent Key system’s operating range be-
comes narrower and may not function
properly.
If the Intelligent Key is within the operating
range, it is possible for anyone, even some-one who does not carry the Intelligent Key,
to push the ignition switch to start the
engine.
The operating range of the engine start
function is inside of the vehicle
O1.
• The luggage area is not included in the operating range, but the Intelligent Key
may function.
• If the Intelligent Key is placed on the in- strument panel or inside the glove box,
storage bin or door pocket, the Intelligent
Key may not function.
• If the Intelligent Key is placed near the door or window outside the vehicle, the
Intelligent Key may function.
PUSH-BUTTON IGNITION SWITCH
POSITIONS
LOCK (Normal parking position)
The ignition switch can only be locked in
this position.
The ignition switch will be unlocked when it
is pushed to the ON position while carrying
the Intelligent Key.
The ignition switch will lock when any door
is opened or closed with the ignition
switched off. ON (Normal operating position)
The ignition system and the electrical ac-
cessory power activate at this position
without the engine turned on.
The ON position has a battery saver feature
that will place the ignition switch in the OFF
position, if the vehicle is not running, af ter
some time under the following conditions:
• All doors are closed.
• The shif t lever is in the P (Park) position.
The battery saver feature will be canceled if
any of the following conditions occurs:
• Any door is opened.
• The shif t lever is moved out of the P (Park)
position.
• The ignition switch changes position.CAUTION
Do not leave the vehicle with the igni-
tion switch in the AUTO ACC or ON posi-
tion when the engine is not running for
an extended period. This can discharge
the battery.

Af ter a period of time, functions such as
radio, navigation, and Bluetooth® Hands-
Free Phone System may be restarted by
pressing the “POWER button/VOLUME con-
trol knob” or the key fob unlock button. For
additional information, see the “Monitor, cli-
mate, audio, phone and voice recognition
systems” section of this manual.
