If the engine 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 or a locksmith 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 ten 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 locksmith
who can service PASS
-Key III to have keys made
and programmed to the system.
See your dealer or a locksmith who can service
PASS
-Key III to get a new blank key that is cut
exactly as a current black colored driver’s key that
operates the system. Do not use the gray colored
valet key for this procedure.
To program the new key:
1. Insert the current driver’s key (black in color) in the
ignition and start the engine. If the engine will not
start, see your dealer for service.
2. After the engine has started, turn the key to OFF and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within ten seconds of removing the previous key.
4. The SECURITY 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.
5. Repeat the 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 start 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 or a locksmith who can service PASS
-Key III to
have a new key made.
