Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to ON, ACCESSORY or START from the OFF
position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.If the engine does not start and the security light
on the instrument panel comes on when trying
to start the vehicle, 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, seeFuses and Circuit Breakers on
page 490. If the engine still does not start with the
other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See
your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to
learn the transponder value of a new or
replacement key. Up to nine additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
121

See your dealer/retailer or a locksmith who can
service PASS-Key®III+ to get a new key blank that
is cut exactly as the ignition key that operates
the system.
To program the new additional key do the
following:
1. Verify that the new key has a
1stamped
on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed and
turn it to the ON position within ve seconds
of removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.
If you lose or damage your PASS-Key
®III+ key,
see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have a new key made.

Programming Universal Home
Remote — Rolling Code
Most garage door openers sold after 1996 are
Rolling Code units.Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these
actions, the device will time out and you will have
to repeat the procedure.

1. From inside the vehicle, press the two
outside buttons at the same time for one to
two seconds, and immediately release them.
155

2. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. It can usually be found
where the hanging antenna wire is attached to
the motor-head unit and may be a colored
button. Press this button. After you press this
button, you will have 30 seconds to complete
the following steps.3. Immediately return to your vehicle. Press and
hold the universal home remote button that
you would like to use to control the garage
door until the garage door moves. The
indicator light, above the selected button,
should slowly blink. You may need to hold the
button from ve to 20 seconds.
4. Immediately, within one second, release the
button when the garage door moves. The
indicator light will blink rapidly until
programming is complete.
5. Press and release the same button again.
The garage door should move, conrming
that programming is successful and complete.
To program another Rolling Code device such as
an additional garage door opener, a security
device, or home automation device, repeat
Steps 1-5, choosing a different function button in
Step 3 than what you used for the garage door
opener.
If these instructions do not work, you probably
have a Fixed Code garage door opener. Follow the
Programming instructions below for a Fixed
Code garage door opener.
