Car lights and everything goes on, but the car will not start
My security system in my car has been broken since early march. i havent need to use the security thing to start the car. yesterday i drove me car home and i parked it. later that night i went tos tart my car. all the lights turned on, everything is working, but the car will not start! The engine or whatever will not turn over to start the car. we checked the everything... can't find anything. could it be the security system not working.
Re: Car lights and everything goes on, but the car will...
Turn key from off to the on postiton. does the security light blink?
if so leave in on postition until light stops blinking (10min) then try to start car. may have to repeat process up to three times.
if the security re-learn process works, you will need a new ignition cylinder with security sensor. if not local gm dealer can tell you for sure.

If the security light is on you can try the 10 min. relearn procedure . Turn the key to run ( not start ) an leave the key on for ten min. If the light goes off in ten . min. turn the key off . Then start the vehicle . If the security light doesn't go off there is a hard fault an you will need to have it diagnosed by a repair shop that knows how .
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. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and 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. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.
it sounds like you have a factory alarm problem and its not leting you start the car. is the security light flashing on the dashboard after you tried starting it? if so you are going to have to reprogram the key. you try to start the car and leave key on until security light goes out it should take about ten minutes or so if light does not go out try again. i have done this on some cars as many as 3 times before it started be careful not to drain battery.after the light goes out shut off key and try to start.
Good Evening, this is a common problem with the early gm anti-theft systems. What I need you to do is go out to your car and try to start it. Then when it does not start leave the key forward in the on position for 11-15 minutes until the security light goes off, then shut the car off and start it up (it will start). If it does not try it a couple more times and you will get it running. What that does is it relearns your key again so the security system will recognize the resistor pellet and allow it to start. Hope this helps.
Your car is equipped with the VATS security system. Cars with this system need a key with a "chip" in it to start the car. A regular key won't start the car because of the security system. A key from the dealership is needed to start any GM car with the VATS system.
The security system is activated. It kills the injector pulse ( signal) and on some modles the starter. You will need to try to relearn the system. First try to start the car, leave the key in the run position for 10 minutes. Cycle the key off, then cycle it to the run position again for 10 more minutes. Cycle it off again, then back to run for another 10 min. after the last cycle turn it off then try to start the car. It is a 30 minute relearn. If this does not work you will need a repair shop to replace the passlock sensor. Good Luck
yes, the security system will cut fuel to the cylinders or stop the car from cranking. what you can do is called a 30 minute re-learn. have everything turned off and a charger hooked up to the battery if possible, put the key in and attempt to start, release key to the run position and let it sit for about 10 minutes or untill the security light goes out. turn key off for 5 seconds and repeat the process 2 more times. after the process is done 2 more times the car should have re-learned the key and it should start. if it still doesn't start the problem might be somewhere else in the security system but try the 30 minute re-learn first. i can assist you with this problem further if needed as i have excellent resources.
