To reset the security system on a 1997 Oldsmobile Cutlass Supreme, first ensure the vehicle is in the "Off" position. Next, turn the ignition key to the "On" position without starting the engine, and leave it there for about 10 minutes. After this period, turn the key back to the "Off" position, wait a few seconds, and then start the vehicle. If the problem persists, you may need to consult the owner's manual or a professional mechanic for further assistance.
