Immobilizer Operation
When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
Your vehicle is equipped
with a passive
theft-deterrent system.
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 5-100. 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 who can service the
theft-deterrent system to have a new key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 additional keys may be programmed for
the vehicle. This procedure is for learning additional
keys only.
The system works when you turn the key to ON. The
key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Canadian Owners: If you lose or damage your keys,
only a GM dealer can service the theft-deterrent system
to have new keys made. To program additional keys
you will require two current driver’s keys. You must add
a step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key.
Then continue with Step 3.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the key
head. If the key is ever damaged, you may not be
able to start your vehicle.
