How to Troubleshoot the Security of an Olds Aleroby Nicholas Smith
One of the most common problems associated with the Oldsmobile Alero is a malfunctioning vehicle security system. Now discontinued, the Oldsmobile Alero was manufactured between 1999 and 2004. It included the "GM Passlock System," which is meant to prevent the vehicle from being stolen. When activated, the system prevents the vehicle from starting. The "security" light on the dash board flashes to alert you that the system is activated. Fortunately, you can reset the security system yourself. If the vehicle fails to start after you perform the reset procedure, the vehicle should be serviced by your mechanic as soon as possible.
Put the key in the ignition and start the vehicle as normal. If the engine will not start, or it starts and dies, the security light should flash. If so, you have identified the security system as the problem.
Wait 10 minutes with the ignition set to the "ON" position. After 10 minutes, the flashing "security" light should turn off, or simply illuminate without flashing.
Turn the ignition to the "OFF" position after the "security" light stops flashing or goes off completely. Wait 20 seconds and start the engine again. If the engine successfully starts, you have fixed the security problem. If not, you must perform a security system "relearn" procedure.
Perform the 30-minute security system "relearn" procedure. The process requires you to repeat these steps three more times. After you repeat the steps of this procedure three times, the system is reset.
