You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming
or disarming the theft-deterrent
system.
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 cluster comes on when trying
to start the vehicle, there may be
a problem with the theft-deterrent
system. 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
Fuses and
Circuit Breakers on page 10 ‑ 38 .
If the engine still does not start
with the other key, the vehicle
needs service. If the 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. 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 or a 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 key blank cut exactly as the
ignition key that operates the
system.
To program the new additional key:
1. Verify that the new key has
a
1
stamped 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 for service.
3. After the engine has started,
turn the key to LOCK/OFF,
and remove the key.
