What does the scurity light in 2004 alero mean?
If you see the security light come on and stay on when you are
driving, it means your "Passlock" system isn't working right. It
happened to me once and then i couldn't start my car. It wouldn't
even studder; it just made no noise. What i did was i read the
manual and it says this:
"During normal operation, the SECURITY light will go off about
five seconds after the ignition key is turned to on and the engine
is started. After attempting to start the engine, if the SECURITY
light flashes or stays on, wait ten minutes with the key in ON
until the light goes off. Then turn the ignition to OFF before
attempting to start the engine again."
So i waited ten minutes and sure enough it worked. I haven't had
that problem since, though.
