First access the ignition switch through the center part of the dash where the radio and climate control are. then locate a thin yellow wire attached to the ignition switch. start your car. then cut the wire. varify the car starts again then tape up the wire you cut put everything back together and there you go.

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

I have a 2001 Chevy Malibu that will not start . I have had a problem with the anti theft system on the car, causing the car not to start.However, I have a new problem that appears not to be related to...


A very common problem for these vehicles is a defective ignition switch. The switch has been redesigned and seems to be a permanent fix, if attempting to replace it yourself I recommend purchasing a repair manual for your vehicle.

When anti theft light is blinking the car wont start. Can you bypass the anti theft device


On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.

Car starts but cuts right back off chevy malibu 05 i put gas in it


may be anti- theft system, best thing to do first is scan computer and see if any codes are stored, then if no codes then check fuel preasure, ill bet there are codes about the theft system. those cars had problems with the ignition that hold the sensor for theft system, but then again could be fuel pump, so scan it first and then we"ll go from there good luck.

Try this I got it from the emission wiz
Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. This relearns your key to the ignition it started with Gm cars and trucks from 1999 to to 2006. It is a big problem but there is no recall that I know of. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

Starts but quits


If the engine starts and then quits when you release the key to the ON position it could be the anti-theft systemhas locked out. Turn your key to the ON position and wait ten minutes until the ANTI-THEFT light on the dash board goes out. The car will now start and run if that was the problem.
