PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.

2-26

PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.When trying to start the vehicle if the engine does not
start and the SECURITY message comes on, the key
may have a damaged transponder. Turn the ignition off
and try again.
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 ªFuses and
Circuit Breakersº 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 additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only.
If all the currently programmed keys are lost or do not
operate, you must see your dealer or a locksmith who
can service PASS
-Key III to have keys made and
programmed to the system.
See your dealer who can service PASS
-Key III to get a
new key blank that is a cut exactly as the ignition key
that operates the system.

2-27
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 ªPK3º 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.
