Canadian Owners: If you lose or damage your keys,
only a GM dealer can service PASS
-Key III to have new
keys made. To program additional keys you will need
two current driver’s keys (black in color). You must add
a step to the following procedure. After Step 3 repeat
Steps 1 through 3 with the second current driver’s key.
Then continue with Step 4.
To program the new PK3 key do the following:
1. Verify the new key has “PK3” stamped on it.
2. Insert the original 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.
4. Insert the key to be programmed and turn it to ON
within 10 seconds of removing the previous key.
5. The SECURITY message will turn off once the key
has been programmed. It may not be apparent that
the SECURITY message 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 message
comes on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key III 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 III key, see
your dealer who can service PASS
-Key III to have a
new key made.
