When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, there may be a problem with your
theft-deterrent system. Turn the ignition off and try

be not damaged, try another ignition key. At this time,

If your vehicle does start, the first key may be faulty.
