2005 CHEVROLET CORVETTE key battery

If you ever notice a decrease in the keyless access
transmitter range, try doing one of the following:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Keyless Access System Operation on page 2-5.
Check to make sure that an electronic device such
as a cellular phone or lap top computer is not
causing interference.
If you are still having trouble, see your dealer or a
qualied technician for service.
Keyless Access System Operation
Your vehicle has a keyless access system that
allows you to lock and unlock your doors, unlock your
hatch/trunk lid and disarm or arm your theft-deterrent
system. The range distance is as much as 100 feet
(30 m) away.
Your vehicle comes
standard with
two transmitters, and
up to four can be matched
to your vehicle. See
“Matching Transmitter(s) to
Your Vehicle” later in
this section.
Q(Lock):Press this button to lock the doors. The
light on the door will ash once. If this button is pressed
two times, the doors will lock, the light will ash and
the horn will sound.

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell 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 break pedal
and the START button, or 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 coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
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.

If your vehicle has lost battery power, open the
hatch/trunk using the vehicle key. The key lock cylinder
is located on the rear of the hatch/trunk lid above the
license plate. Turn the vehicle key clockwise in the lock.
If your vehicle has a convertible top and has lost
battery power, you can also use the emergency trunk
release handle to open the trunk. See “Emergency
Trunk Release Handle” following.
Closing the Rear Compartment
To assist in closing the rear compartment lid of your
coupe, use the pocket on the underside of the lid on the
passenger’s side of the vehicle.
When closing the lid on either the coupe or convertible,
lower the rear compartment lid until the power pull
down feature activates and the rear compartment lid will
close the rest of the way and latch automatically.
2-15

Arming the System
Use one of the three following items listed here to arm
the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power door
lock switch. The security light should ash.
Remove the keyless access transmitter from inside
the vehicle and close the door. The security light
will stop ashing and stay on. After 30 seconds, the
light should turn off.
The vehicle can be programmed to automatically
lock the doors and arm the theft-deterrent system
when you exit the vehicle. SeeDIC Vehicle
Personalization on page 3-69.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. Your vehicle will not start without a
keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver’s door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
Testing the Alarm
Do the following to test the system:
1. Make sure the trunk lid is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually pull
the release lever on the oor.
6. Turn off the alarm by pressing the unlock button on
the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and Circuit
Breakers on page 5-85. If the horn works, but the
alarm doesn’t go off, see your dealer.
Disarming the System
Always use your keyless access transmitter to unlock a
door either by pressing the unlock button on the
transmitter or by squeezing the door handle sensor
while you have the transmitter with you. Unlocking a
door any other way will set off the alarm. If your alarm
sounds, press the unlock button on the keyless
access transmitter to disarm it.

Information Center (DIC). If an automatic vehicle is
not correctly placed in PARK (P) a SHIFT TO PARK
message will display on the Driver Information
Center (DIC).
For more information, seeDIC Warnings and Messages
on page 3-54.
Notice:If you do not put a manual transmission in
REVERSE (R) before exiting your vehicle, your
vehicle will not be secured, the battery will drain
and could be damaged. Always put a manual
transmission in REVERSE (R) before shutting off the
engine and exiting the vehicle.
When the engine is off, press this button to place the
vehicle in accessory mode. ACCESSORY MODE
ON will display on the Driver Information Center (DIC).
This mode allows you to use things like the radio
and the windshield wipers while the engine is off. Use
accessory mode if you must have your vehicle in motion
while the engine is off, for example, if your vehicle is
being pushed or towed.
After being in accessory mode for about 20 minutes, the
vehicle will automatically enter RAP or OFF, depending
on if the doors are opened or closed.

Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, the engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on
how to add oil, seeEngine Oil on page 5-13. After
the competitive driving, remove excess oil so
that the level on the dipstick is not above the upper
mark that shows the proper operating range.
Vehicles with the Z51 performance package have
greaseable outer ends on both of the rear toe-links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. SeeScheduled
Maintenance on page 6-4andRecommended Fluids
and Lubricants on page 6-12. If you use the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer for lubrication
and make sure any needed repairs are made at once.
Proper procedures for performing these services can be
found in the service manual. SeeService Publications
Ordering Information on page 7-11.
