2007 CHEVROLET CORVETTE key fob battery

Battery Replacement
Under normal use, the battery in your keyless
access transmitter should last about three years.
The battery is weak if the transmitter will not
work at the normal range in any location. If you
have to get close to your vehicle before the
transmitter works, it is probably time to change
the battery.
A weak battery may also cause the DIC to display
NO FOBS DETECTED when you try to start the
vehicle. If this happens, place the transmitter in
the glove box transmitter pocket with the buttons
facing towards the passenger’s side. Then, with the
vehicle in PARK (P) for an automatic transmission,
press the brake pedal and the START button. If
your vehicle has a manual transmission, press
the clutch and the START button. Although this
will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible.
The DIC may display FOB BATTERY LOW.
Notice:When replacing the battery, use
care not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.1. Insert a at object with a thin edge into the
slot on the side or back of the transmitter
and separate the bottom half from the top half.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter,
positive (+) side down. Use a battery,
type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
These features continue to work up to 10 minutes
after the engine is turned off or until either door
is opened. If a door is opened, the power windows
and audio system will shut off.
Starting the Engine
Move the shift lever to PARK (P) or NEUTRAL (N)
for an automatic transmission. For a manual
transmission the vehicle can be started in
NEUTRAL or any other gear as long as the clutch is
depressed. To restart a manual transmission when
you are already moving, use the NEUTRAL position
only. To restart an automatic transmission when
you are already moving, use NEUTRAL (N).Notice:Do not try to shift to PARK (P) if
your vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
The keyless access transmitter must be inside the
vehicle for the ignition to work.
Cell phone chargers can interfere with the
operation of the Keyless Access System. Battery
chargers should not be plugged in when starting
or turning off the engine.
To start your vehicle, do the following:
1. For an automatic transmission, with your foot
on the brake pedal, press the START button
located on the instrument panel. For a manual
transmission, while pressing in the clutch,
press the START button.
If there is not a keyless access transmitter in
the vehicle or if there is something causing
interference with it, the DIC will display
NO FOBS DETECTED. SeeDIC Warnings
and Messages on page 214for more
information.

2. When the engine begins cranking, let go of
the button and the engine cranks automatically
until it starts. If the battery in the keyless
access transmitter is weak, the DIC displays
FOB BATTERY LOW. You can still drive
the vehicle.
See “Battery Replacement” underKeyless
Access System Operation on page 73for more
information. If the fob battery is dead, you need
to insert the fob into the fob slot to enable
engine starting. See “No Fobs Detected” under
DIC Warnings and Messages on page 214.
3. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently until the oil warms up and lubricates all
moving parts.
4. If the engine does not start and no DIC
message is displayed, wait 15 seconds
before trying again to let the cranking motor
cool down.
If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedalall the way to the oor while cranking for
up to 15 seconds maximum. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the accelerator. If the vehicle
starts briey but then stops again, do the
same thing. This clears the extra gasoline
from the engine.
Notice:Cranking the engine for long periods
of time, by pressing the START button
immediately after cranking has ended, can
overheat and damage the cranking motor,
and drain the battery. Wait at least 15 seconds
between each try, to allow the cranking
motor to cool down.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. Once cranking has
been initiated, the engine continues cranking for a
few seconds or until the vehicle starts. If the engine
does not start, cranking automatically stops after
15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 90. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will
be on, but the engine will not start — if you pressthe bottom of the Acc. button only briey, less than
ve seconds, the accessory power mode will be
turned on, but not the ignition. After the bulb check,
be sure to press and release the Acc. button again
to turn the ignition off and avoid draining the
vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced
the battery or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This may take several days of routine
driving. If you have done this and your vehicle
still does not pass the inspection for lack of
OBD system readiness, your dealer can prepare
the vehicle for inspection.

If moving the transmitter to different locations
within the vehicle does not help, place the
transmitter in the glove box transmitter pocket
with the buttons facing to the right and then
press the START button.
The vehicle’s battery voltage is low. The
battery voltage must be above 10 volts
for the keyless access transmitter to be
detected properly.
NO FOB - OFF OR RUN?
This message displays when the keyless access
transmitter is not detected inside the vehicle while
you are trying to turn the ignition off. Your vehicle
may be near a strong radio antenna signal causing
the keyless access system to be jammed. The
vehicle will remain in Acc. until OFF or START has
been pressed or ve minutes has expired. If you
turn the ignition off and you cannot nd the keyless
access transmitter, you will not be able to restart
the vehicle. The keyless access transmitter needs
to be inside of the vehicle in order for the vehicle to
start. SeeStarting the Engine on page 91for more
information.
OPTIONS UNAVAILABLE
This message displays for a few seconds if a
keyless access transmitter that is not labelled 1 or 2
is used and you try to personalize the features on
your vehicle by pressing the OPTION button.
The personalization system will not recognize
the transmitter and the DIC will not display the
current driver number or the menus used to set
personalizations. The personalization features will
then be set to the default states. SeeDIC Vehicle
Personalization on page 234for more information.
