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.
For
battery replacement
use
two Duracells batteries,
type DL-20 16, or a similar
type.
