change key battery CHEVROLET IMPALA 2007 9.G Owners Manual

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in range. This
is normal for any remote keyless entry system.
If the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter
to work, try this:
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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry (RKE) System
Operation on page 91.
If you are still having trouble, see your
dealer/retailer or a qualied technician
for service.
Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be unlatched from about
3 feet (1 m) up to 65 feet (20 m) away with the
remote keyless entry transmitter.
If your vehicle has the remote start feature you
can also start your vehicle with the remote keyless
entry transmitter. Your remote keyless entry
transmitter, with the remote start button, provides
an increased range of 195 feet (60 m) away.
However, the range may be less while the vehicle
is running. As a result, you may need to be
closer to your vehicle to turn it off than you were
to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry (RKE) System on page 90.

Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
four 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.
The REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
remote keyless entry transmitter battery is
low. See “REPLACE BATTERY IN REMOTE KEY”
underDIC Warnings and Messages on page 199
for additional information.

care not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery in the remote keyless entry
transmitter do the following:
1. Use a at object with a thin edge into the
notch, located below the trunk release
button, and separate the bottom half from
the top half of the transmitter.
2. Remove the old battery, but do not use a
metal object to do this.
