Canadian Owners: If yo?!
lose
or danage your keysj
only a GM dealer can service PASS-Key@ Ill to
have new keys made. To program additional keys you
will need two current driver's keys. You must add a
step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver's key.
Then continue with Step 3.
To program the new key, do the following:
1. Verify that the new key has PK3@ stamped on it.
2. Insert the current driver's key in the ignition and
start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
5 ; The SEGlJRITY telltale light will turn off once the
key has been programmed. It may not be apparent
that the SECURITY light went on due to how
quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key@ Ill system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key@ III system at this time.
If you lose or damage a PASS-Key@ Ill key, see your
dealer to have a new key made.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
