I had this problem on my 99 Alero and I had to take it to the dealer for a $520 repair. I researched this issue before taking mine to repair and all i found was the same answer. This is the best option you have to be rid of this annoying problem... Here is a step-by-step procedure:
Pry up the plastic molding from around the Radio/HeaterAC controller and from around the Gear Shifter. Detach the HeaterAC module from the molding by removing the four 7-mm hex bolts from the back side. Take out the 3 7-mm hex bolts to loosen the Radio. Put key in ignition & turn to "On" position, apply brake, and shift into "drive" or lower gear. Turn HeaterAC module to the left, sideways orientation, and pull out the Radio. Disconnect main wiring harness from back center of Radio if there is not enough slack to take the Radio out past the plastic molding. Leave the antenna connected. Look inside and to the left at the back of the Ignition Cylinder assembly. Locate the THIN YELLOW WIRE which is bundled alongside the thin white and the thin black wire. You may have to stick you hand in and fish a bit to grab this "Thin wire Trio". DO NOT mess with the main rear/downward ignition wiring harnesses (1 of which contains a Thick Yellow Wire - leave it alone).
Isolate the THIN YELLOW WIRE from the 2 others. As a precaution, RECONNECT the MAIN RADIO WIRE HARNESS, and let the Radio hang to the right side. Put the key in the ignition, and put the car back in PARK. START THE CAR. CUT THE THIN YELLOW WIRE with the car running. Tape both ends of the cut wire. Place black electrical tape over the "Security" light (less annoying). Turn off the car engine. Disconnect the Radio main wire harness to Re-Install the Radio, if necessary. You may need to crawl under the passenger-side dash to push the main wire harness back into the radio while holding the Radio from the front. The rest of the installation is the reverse of removal. YOUR LIFE JUST GOT A LOT BETTER if you want to keep driving this car !!

I have an Oldsmobile alero 99 and the security light is constantly on however the car starts leading me to believe the security feature is not working. How can I fix the problem?
I wouldn't fix it if i was you.....I have a 2000 alero, and the security system (passlock) keeps it from starting often, and it seems to be a big problem with them. So if your security system isn't working but the car is running fine I wouldn't mess with it..

It's probably related to your security system. If that's the case you'll need to take it to a dealer to get it cleared up. I found out after countless hours of working on my sister's Alero that they're Oldsmobile's version of the Edsel.
