If the engine still does not start, and the key appears
to be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see “Fuses and
Circuit Breakers” in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer who can service the PASS
-Key III to
have a new key made.
It is possible for the PASS
-Key III decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
This procedure is for learning additional keys only.
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 require
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.
4. Insert the key to be programmed and turn it to ON
within 10 seconds of removing the previous key.
5. The SECURITY 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 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 to have a new key made.
