senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.

security light on the instrument
panel 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.

the key appears to be undamaged,
try another ignition key and check
the fuses. SeeFuses and Circuit
Breakers on page 10‑31 for

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

and programmed to the system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
