There I s a master key that
works in all of the lock
cylinders (driver's door,
trunk, ignition, and
glove box).
There is also a VALET key
which only operates the
driver's door and the
ignition.
Your vehic!e has the p . 4 S S - k ~ ~ !!I vehicle theft
system. Both the master and VALET key have a
transponder in the key head that matches a decoder in
the vehicle's steering column. If a replacement key
or any additional key is needed, you must purchase this
key from your dealer. The key will have PK3m stamped
on it. Keep the bar code tag that came with the
original keys. Give this tag to your dealer if you need a
new key made.
Any new PASS-Key@ I l l key must be programmed
before it will start your vehicle. See PASS-KeY 111 on
page 2-19 for more information on programming
your new key.
If your vehicle is equipped with the Onstar@ System
with an active subscription and you lock your keys inside
the vehicle, Onstar@ may be able to send a command
to unlock your vehicle. See OnStap System on
page 2-40 for more information.
Notice: Your vehicle has a number of features
that can help prevent theft. 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
spare keys.
