One key is used for the
ignition and all locks.
When a new vehicle is delivered, the key has a
bar
- coded key tag. This tag may be removed by your
dealer before it is delivered.
Each tag has a key code on it that tells your dealer or a
qualified locksmith how to make extra keys. Keep the
tag in a safe place. If you lose your keys, you’ll be able
to have one made easily using this tag. If you need a
new key, go to your dealer for the correct key code. In
an emergency, call the Oldsmobile Roadside Assistance
Center at 1
- 800 - 442 - OLDS (6537). (In Canada, call
1 - 800 - 268 - 6800.)
NOTICE:
Your vehicle has a number of new features that
can help prevent theft, therefore 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.
