Buick 2000 Park Avenue Owner's Manual page 68

The master key is used
for the ignition, as well
as all door locks and
storage compartments.
The valet key is used for the
ignition and the two side
doors only. It will not open
the trunk or glove box.
-
This is a theft deterrent
feature. The valet key
should always be used
when valet parking
your vehicle.
When a new vehicle is delivered, the dealer removes the
-
bar coded key tags from the keys, and gives them to the
first owner.
Each tag has a code on it that tells your dealer or a
qualified locksmith how to make extra keys. Keep the
tags in a safe place. If you lose your keys, you'll be able
to have new ones made easily using the tag. The
replacement key must have a transponder embedded
in it.
NOTICE:
Your vehicle has a number of features that can
help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your keys inside. You may even have to damage
your vehicle to get in. So be sure you have
extra keys.
