What is going on when your security light for a 1997 olds achieva stays on and car won't start?

Oldsmobile Passlock Security System

From the Oldsmobile Achieva owner's manual:

Passlock (TM)

Your vehicle is equipped with the Passlock theft-deterrent system.

Passlock is a passive theft-deterrent system. The system is armed once the key is removed from the ignition. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used, fuel is disabled.

During normal operation, the SECURITY light will go off after the engine is started. If the engine stalls and the SECURITY light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from the START position as soon as the engine starts. If you are driving and the SECURITY lights comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your retailer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse or circuit breaker. See your Oldsmobile retailer for service.

If the SECURITY light comes on while the engine is running, a problem has been detected and the system may need service. See your dealer for service.

Note: my Achieva has a 'bypass' switch located in plain sight on the lower side of the dash near the hood release latch. I have had to push that button while trying to start the car. I did not have the remote on that key chain. If you have a remote, make sure the batteries are fresh and try to resynchronize the remote to the vehicle following this procedure:


Your Remote Lock Control system is equipped with a security system that prevents anyone from recording and playing back your signal. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent to it more than once. To resynchronize your transmitter and receiver, follow these directions:

1. Stand close to your vehicle

2. Press and hold the LOCK and UNLOCK buttons on the transmitter at the same time.

3. Hold the buttons for five seconds. In this time, the doors should lock and unlock once. This confirms the resynchronization. If the doors do not lock and unlock, see you retailer for service.

why don't you do just what i did? disable the security! nobodys going to steal an achieva anyway unless they are crazy then they would probably bring it back! lol take off the cover to the steering column. look on the passengers side of the column and you will see 3 small 20 gauge wires, yellow, white, and black. cut the yellow wire. problem solved! security is now disabled. your security light on the dash will stay on all the time now when running but isn't that better than paying hunderds of dollars for maybe nothing? I know this works cause i had to do it on my 97 achieva. Good luck
