from the above site:
It worked well for me for about ten years, but I finally got fed up
with not being able to start my own car with my own key. I don’t like
to get screwed on car repairs, so here’s what happened. I used Google
for a while and found some websites with more information than I really
needed, and I read it all. If you are having the same problem, you have
probably figured out what is going on. You turn the key. The car
doesn’t start, but the ‘SECURITY’ indicator blinks. You give up, and it
stays lit. You know that the little resistor in the key is not making
good contact.
You can go Google for those other sites as well, but you really
don’t need all the information they give. I had been putting off the
job because I thought I was going to have to crack open my steering
column. This was not the case. Here’s how it worked on my 97 Camaro:
This is much better than having to try 6 times, waiting 4 minutes
between each attempt, when I’m already late for work. I am thrilled to
know that when I go to start my car tomorrow morning it will not be a
50/50 chance.

the system is reset anytime you open the driver or passenger door from the locked position, either with the key or the remote, so u have a malfunction and need to see the dealer for diagnosis and repair, only they have the special electronic scanner to diagnose this.
