Security light shut down

Asked by Mar 06, 2018 at 03:00 AM about the 2002 Oldsmobile Alero

Question type: Maintenance & Repair

I have a 2002 Alero that won’t start.  At first I
thought it was my fuel pump but found out it
wasn’t.  I let a mechanic look at it and he said the
security system shut down my car and he had to
disengage the system.  My car ended up starting
again after he did this.  A few days later my car
wouldn’t start again and now he saying it may be
my ignition.  I don’t know anything abt cars and just
want to know does any of this sound familiar?

My guess is that he "reset" the security system. You can do this with an easy procedure. (i'll paste that below for you) But in my experience, if the security system failed enough to need a reset, it is probably failing beyond what a reset can do. Do you see a light on the dash that says SECURITY when it doesn't start? If so, the security system is bad, and resetting it will be a common occurrence for you until you fix it, or bypass it.

Perform the re-learning procedure............... Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON (vehicle will not start). Observe the SECURITY light, after approximately 10 minutes the light will turn OFF. Turn OFF the ignition, and wait 10 seconds. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes The vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK. Start the engine (the vehicle has now learned the Sensor Data Code and/or password).
