Cadillac 2005 DeVille, Owner'S Manual, Page: 66 / 416

There is a master key that works 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 vehicle has the PASS-Key
®
III 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 PK3 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
®
III key must be programmed before
it will start your vehicle. See PASS-Key
®
III on page 2-21
for more information on programming your new key.
Notice: If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
In an emergency, contact Cadillac Roadside Assistance.
See Roadside Service on page 7-5.
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 OnStar
®
System on page 2-42
