Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry 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 GM dealer. Remember to
bring any additional transmitters so they can also
be re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. The vehicle can
have a maximum of eight transmitters matched to it.
See Remote Key under DIC Operation and Displays on
page 3-40.
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” under DIC Warnings and
Messages on page 3-46 for additional information.
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.
To replace the battery in the remote keyless entry
transmitter do the following:
1. Use a flat 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.
