The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. These 3 parts are in CONSTANT communication. If the key is in the ignition, these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle.

    This car is a 2000 Saturn and has no auto door locks or windows, all it has is a security light flashing with a start and stall.

SOURCE: 2002 Saturn S-series Passlock needs to be reset

Try this first, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help

SOURCE: how to disable passlock system on 2000 Chevrolet

There isnt any way to disable it that I know of, if you could, anybody could steal the car. It just needs to be fixed by a qualified repair shop or the dealer.

Will not start but turns over


Check if security light is on, if so, must reset. To reset, put key in ignition and turn to on position. Security light will start flashing on and off. Leave key in on position until security light stops flashing and turns off completely. This will take approximately 10 minutes. Then turn key off and take out of ignition. Put key back in and start car. Should now start

I have a 2001 L100 seires Saturn and My service light and the security light both are on and the car wont start. the battery seems to be fine all the lights work i left it alone for a while and it started...


No, the fuel gauge not working wouldn't have anything to do with your not starting problem , probably the gauge is bad . With the SECURITY light lit , anti-theft system problem ! Service light ????? Service engine soon ? Or service vehicle ? With the light's on code's DTC'S - diagnostic trouble codes are stored . Have it checked , don't guess as to what the problem is. This would prevent the buying of un needed parts .

02 saturn car starts then shuts off within 5 sec put new computer in it cause of step daughter hooking jumper cables up backwards. any ideas. have put on scanner and only found evap codes.


Check security light, if it is flashing , it is set. try this, turn ignition on, don't try to start, let set for ten minutes on. turn off don't take the key out. do this three times ten minutes each, after the third time turn it off, then try to start. This resets the security. If this does not work, then it needs reprogrammed to the new computer you installed. dealer only, about $100.00

My entire system has shut down, and someone said it's the security system. Where's the switch or reset button?


>security system. Where\'s the switch or reset button?

If it was that easy why have a security system? GM does it again.

This worked on a 2000 so try it and see if it works on yours.

(1)Turn key to crank & then release. Security light still on. Wait till it goes off (maybe 15 minutes)
(2)Turn to off. Repeat step one.
(3)Turn to off. Repeat step one.
(4) Turn to off. Wait 20 seconds and start car.


Key must go to full off on each pass. Must have fully charged battery. Good Luck.

Even if this does not work a good testimonial would be appreciated

to reset passlock system, Turn the engine two seconds then leave the key in the run position for exactly ten minutes...the anti-theft security light should go from blinking to solid at the ten minute mark. Immediatly run the engine and the Passlock is reset. Good Luck!!

How to reset security after changing battery


The security system shouldn't keep you from getting it out of park. Check to see if the security light is flashing. I can tell you how to reset the security system.

Have a 2003 Saturn LW2 wagon- 1st problem lights inside and outside of car started blinking on & off- then just opening car door lights blinked on & off- now blinking stop-but car will crank over-...


That thing about the lights flashing, think about it. that happens only when you lock or unlock the car with remote to set and off-set the security system. Makes sense that your security system is in lock-out mode so nothing works, right?. Disable or reset your security system and you'll be fine.

Code reset


I would not recommend just resetting the light unless you have corrected the reason it was on…..Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.
