PASS-Key' I1
Your vehicle is equipped
with the PASS-Key I1
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key I1 is a passive
theft-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS-Key I1 uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS-Key I1 system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. For about three minutes, the starter
won't work and fuel won't go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to
make a match.
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY light is on, the
key may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuses (see "Fuses and Circuit Breakers" in the
Index). .If the starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS-Key 11.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work and the
SECURITY light will come on. But you don't have to
wait three minutes before trying another ignition key.
