The key your using is not programmed or the anti theft system has failed. Take to your local dealership to program or fix the cause of the concern.

Where is tha kill or reset switch on a 2001 ford mustang that wont start?

If you mean theft system activated, it can only be reset through computer by an auto locksmith or dealer. If light flashes when key is on, theft was detected. If light is not on and you have no fuel at schrader valve on rail- you can try inertia switch for fuel.

How do you deactivate an anti-theft system on my 1996 Chevy cavalier the fuse does not do anything with the theft system light on the car will not start this is factory?

Remove the fuse. smokingallowed say's: Removing the fuse will only erase the memory from the computer,and it will have to relearn what it should know. It will not reset the theft system. Here's how to reset the theft system. Roll the window down,(if power windows,turn the key off again)reach thru the window and try to start the car. When it don't start just leave the key on for around 20 minuets or so. If you dont leave it on long enough you will have to go through this waiting period again, but 20 mins. should do the trick. Then turn the key off for about 30 seconds, then start the car. P.S. Dont do anything electrical,like, push the brakes,open the door,mess with the radio. Just reach through the window to turn the key. I own three z24's... 97'97'99...On 2 of them('97 & '99) the theft system light will flash when it is activated and stop flasing after 20 mins. when it is reset, but the 3rd car('97) theft system light will not flash, just be lit and go off after the car is started.


2000 Malibu anti-theft light is on car will not start Put used ingnition switch.?

If its the same as my 2001 malibu, you turn the key to the on position leave it on for about 10 mins. When the security light goes off turn the key to off. You should then be able to start the engine normally. Its the worst system ever devised.
