Matching Transmitter(s) To Your Vehicle
Each key chain 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 the remaining transmitter
with you when you go to your dealer. When the dealer matches the
replacement transmitter
to
your vehicle, the remaining transmitter must also be
matched. Once the new transmitter is coded, the lost transmitter will not
unlock your vehicle.
You can match a transmitter
to
as many different vehicles as you own,
provided they are equipped with exactly the same model system. (General
Motors
offers several different models
of these systems on their vehicles.)
Each vehicle can have only two transmitters matched
to
it. See your dealer
to match transmitters to another vehicle.
Battery Replacement
Under normal use, the batteries in your key chain transmitter should last
about two years.
You can tell the batteries are weak
if
the transmitter won't work at the normal
range in any location.
If
you have
to
get close to your vehicle before the
transmitter works,
it's
probably time
to
change the batteries.
