My key turns over but it won't start. All the lights and everything else works. I believe its the anti lock system. How do I get it to start on my own?

If by "anti lock" you mean "pass lock" which is the GM passive anti theft system then you can try this...

put the key in the ignition, turn the key all the way to on (not to the point of trying to start it just to the ON position) 3 times , on off, on off, on off, on at this point leave the key in the on position for 15 minutes, after the 15 minutes turn the key back off and try to start it.

there are two varations of this reset method that I'm aware of... the other variation is similar to a point. key in, on off, on off, on off, on leave on for 15 minutes then turn the key to start without turning to off first.... if the first method doesn't work, try the second. I believe there is another method that involves the key fob remote if your car has one. I will try to see if I can find those instructions just in case the first two methods arent of any help..

SOURCE: won't start

very well could be due to anti theft issue. i don't recall the keys getting locked in the ignition from this though. try turning the key to the on postion- not cranking and leave it there for 15 min, then turn back off. do this three times. you may get a blinking light on the dash- don't worry about it. on the fourth try and start it. what you are doing is telling the alarm- i have the proper keys so let me take my car!

SOURCE: Hello I have a 2002

Yes there is a bypass. Costs about $200.00. You should be able to put the key close enough to the cylinder to get the security to go off. I don't know what you did to get the cylinder out. but there is a chip mounted to the steering column. once the key is close enough to it it will let the car start. If you broke the chip getting the cylinder out then you have some money to put out to get it running.

Citroen c3 2006 anti-theft


I had the same problem.when I used my main key my car wouldn't start and I got the message "anti theft faulty". The key and the remote still unlocks and locks the doors and turns the lights on/off but it just wouldn't start my car. I was able to start my C3 by using the spare key. The main key is still faulty and if used brings up the same message.

1997 chevy malibu anti theft system how do I fix this problem The car won't start I believe the car is in the anti theft mode


The late-90's GM Passlock system (e.g. 1997 Malibu, Regal, Impala, etc.) has a part around the ignition tumbler that goes bad and no longer reliably detects the valid key. In that situation, the "Theft System" light will slowly flash and the carburetor is cut off so the engine won't start. The time-out on the system is 10 minutes - you don't have to do anything, you don't have to disconnect the battery, the key can be out of the ignition -- it's just a time delay. After 10 minutes, the light goes out and you can try again (but if the key is again not detected, the light will start flashing again and you have to wait another 10 minutes)
Someone else, who had this problem, told me to remove all other keys from my keyring. The weight of the other keys pulls on the ignition key causing the key to be unreadable. It has been 7 weeks since I have been doing this and have not had a problem

You most likely have a failed anti theft system. Go to this link to read about these systems. I have no permanent fix for you, but you might be able to bypass the anti theft parts at the ignition. This might get you going. http://vatspasslockpasskeysecurityhelp.yolasite.com/
