Mine came on the other day while driving so i turned the car off and restarted it and I haven't had it on since. Anybody know?

 

Always check your manual first:

The key must be clean and dry before it’s inserted in the
ignition or the engine may not start. If the SECURITY
light comes on, the key may be dirty or wet.
If this happens and the starter won’t work, turn the
ignition off. Clean and dry the key, wait three minutes
and try again. If the starter still won’t work, wait
three minutes and try the other 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.
If you accidentally use a key that has a damaged or
missing resistor pellet, you will see no SECURITY
light. You don’t have to wait three minutes before trying
the proper key.
If the resistor pellet is damaged or missing, the starter
won’t work. Use the other ignition key, and see your
dealer or a locksmith who can service the PASS-Key to
have a new key made.
If the SECURITY light comes on while driving, have
your vehicle serviced as soon as possible.
If you lose or damage a PASS-Key ignition key, see
your dealer or a locksmith who can service PASS-Key.

Happened to my Impala, eventually would not start, had to have several modules replaced. Cost was abot $500. Then again it could be a freak happening, some electrical interference (strong radio waves).

 

$500? Yuck! I have drove it several time since and have no light so maybe it won't come back on.

 

The security light is part of the PASS-Key system. Which includes the little resistor pellet on the ignition key. You might just have had a speck of dirt on the key or perhaps it wasn't inserted just right or moved when you hit a bump. It sounds like whatever it was cleared itself when you removed the key and restarted the car. Keep an eye on it as it could mean that you need to have the ignition switch replaced. Be alert for a "Remove key and wait ten seconds" message on the DIC as well. This is not necessarily related to a pending column lock issue but a security issue with reading the correct resistance on the key.

Well every time I remove the key for a while I always get the pull key wait 10 sec. message. If I don't remove the key I never have a problem. I installed the k harness and removed the lock plate but the k harness only lasted about a month. So I bought the CLB from Corvettes of Houston and I always get the pull key message. I have heard alot of people say that is common on the 97 if you have the CLB.

 

Yes it is. I didn't make the connection (no pun intended) to you having a CLB. Since the two systems are closely related it could be just symptomatic of the pull key message.

 

I guess there is not much that can be done about the pull key message so I 'm going to have to deal with it. Thanks man

 

My security light came on one day as I was driving on some rough road. I guess the bumps made the key jiggle enough to throw a code. Isn't there an anti-theft mechanism that reacts to harsh impact or something that could cause the light to come on?

 

Hmm, I guess I don't know.

 

I remember that my 98 camaro had an anti-theft mechanism that was located right over the right rear wheel that would shut off the fuel if the vehicle was in an accident or being towed? It would reset automatically in a few minutes...

 

Same thing happened on my Z16 yesterday. Threw 3 codes on DIC....40-BCM, AO LDCM, A1 RDCM. Shut engine off...restarted...securit light off! After 4 starting cycles the codes wnt from current to H.
