How do you disable the anti-theft lock on a 1999 Chevy Malibu?

Answer:
Take it to the dealer an they have that information.

Answer

Sorry, I am not sure how to disable it. But I have learned that you must sit and wait a "greuling" 15-minutes for it to reset itself before you can try and start the car again.
Pull out the stereo with out disconnecting, and find 3 really thin straped cables, yellow, black and white. Start the car and cut the yellow wire. That�s it, the anti theft light, would be on always but the system would be deactivated.

SOLUTION!!!
Here's your somewhat detailed solution:
Take a flat screwdriver and pop off the trim that surrounds the radio and heater controls. Oh yeah... the trim around the key hole has to come off also. Don't unhook the wires from the radio or the heater controls. You will need a small socket set or a good pair of pliers to take out 4 small bolts. One on each side of the radio and the heater controls. Be sure the car is running when you cut the yellow wire. There are 3 wires (black, white and yellow) wrapped in black cloth tape that you will have to "fish out" from under the ignition switch with your finger. You'll find the wires just about even with where the radio was. Again be sure the car is running then cut the yellow wire and leave the ends where you can find them in case you ever have to hook them up and cut them again! Theft light will come on and remain on forever. Radio is aggravating to put back in because you must line up a "male female" bracket correctly or the cover will not go back on...no big deal just look closely and you'll see the male fitting on the back of the radio and the female fitting inside the dash. Good luck! MrSparex


Bring it to the dealer and have your ignition lock cylinder replaced.




Hi! you dont need to pay the $ at dealer. get a new key made. the theft light is activated because your key is kinda worn and it doesnt recognize it. and it takes exactly 10 min. for the light to clear, not 15.
