If the security light remains on while cranking then 90% of the time it is caused by a broken wire coming off the ignition key lock cylinder. This repair should be done by a professional..

Make sure your pats key is clean. Sometimes the chip gets dirty. Also try disconnecting the battery for a couple of minutes. This will reset the system...

SOURCE: The battery died on my

Im pretty knowledgable in the whole SECURITY light issue... I dont think this could cause the door lock to not work correctly, but anything is possible. Newer cars are wound up pretty tight. Here is a link to help understand how the security works.

I'd go ahead and do a "security relearn" on you car. It might help if that is what caused the door issue.
Turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) Turn back your key to regular position and check the door lock. May have to do this process 3x

1998 corvette will not start says reduced power


If the security light is blinking it will not start. The security system needs to be reset. You will have to have a fully charged battery to reset the system. With a full charged battery turn the ignition forward until the warning lights come on and leave the key in the on position for 15min. Turn key off and wait 10sec. then try and start.You may have to perform this procedure a couple of times, however, it is usually successful the first try. The reduced power light can be set by a low voltage/poor charge battery

Changed battery in 2004 corvette and car won't start security light is on


Make sure you turn all accessories off maybe even put a charger on before you do this. After turning the ignition switch to the start position release it to the run position for approximately ten minutes. The security light should go out. Turn ignition switch to the off position for 10 seconds. Then restart. It may take up to three of these procedures to relearn but in your case it usually works on the first try.

My 2000 corvette won't crank up---no lights will come on-----nothing works in dash, not even the radio


I would take the battery cables loose and actually verify battery is not leaking. If "security" is causing no start then you can tell by watching the security lamp on dash. It should be on solid when key is turned to run if it is part of your concern. also sounds like you could have a body control module problem it controls the interior lamps which may explain clicking you heard and also controls the security.

Keep us updated.

My car will not stay started! It will turn over but then shut off after a few seconds! It is equipped with a carbine 4800 alarm. I have changed the cap, rotor wires, plugs, ICM, idle air sensor, fuel...


This sounds like the anti theft security system failing. Very common on GM vehicles, especially 80's Corvettes. The system was originally designed with a starter disable system if the security key was not correct. (or if it was being stolen) Corvette and Cadillac started using a fuel disable system since people would just the starter to steal them. The symptoms are exactly what you describe. Vehicle starts and runs for 1-5 seconds and then dies. It is actually turning off the fuel injectors. You may even see the security light turn on afterwards.

1996 vette has new battery running fine and now wont start


The security, antitheft or lock picture/icon 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 (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then 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 misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Is there a reset after I change the Battery on my 98 Corvette


Hello,
There is no reset button for your Corvette. You may have an issue with the security system. Check if the Security light is on or flashing while trying to start the car.
I hope this helps.

Thank You,

94 vette won't start,bat good,have org. key,fuses ok,high beam light on lights off,lcd cluster won't light up?


Disconect the battery and ECM for FOUR DAYS then reconect the ECM and BATTERY. Let it sit for another four days without turning anything on. It should start but will run rough for about 200 miles as the ECM relearns the system. I had the same issue and that is what fixed it.
