2007 GMC SIERRA CLASSIC battery replacement

At times you may notice a decrease in range. This
is normal for any RKE 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 System
Operation on page 117.
If you are still having trouble, see your dealer
or a qualied technician for service.

Matching Transmitter(s) to Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to
bring any remaining transmitters with you when
you go to your dealer. When the dealer matches
the replacement transmitter to your vehicle,
any remaining transmitters must also be matched.
Once your dealer has coded the new transmitter,
the lost transmitter will not unlock your vehicle.
Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about two 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.
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.

When using the wired headphones, if the front
seat passengers play a CD in the Radio with

Radio Service (if equipped), you will hear the audio
for these sources, instead of the DVD or CD
that is currently playing through the RSE.

or direct sunlight. This could damage the
headphones and repairs will not be covered by
your warranty. Keep the headphones stored
in a cool, dry place.
