With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

Try disconnecting your battery cables then wait about 10 minutes. The computer should reset itself. Reconnect the wires to the battery. It is normal for the theft light to blink about every 5 seconds when the ignition key is out or in the off position. This means the system is armed and working properly. Hope this helps. God bless!

Try to start car. When it fails leave the key in the on position. You will see the Theft System light flashing. Light will flash for 10 minutes, stay on and then go off. Turn key to off position, wait 10 seconds and start your car.

Don't waste your time or money taking this problem to a dealership because Chevy refuses to issue a recall on this problem. I went to the dealership 5 times. I wound up paying for 2 key cylinders, a BCM module, an ECM module. I finally took it in when the theft system light came on while driving. The problem was in the fuse & relay center underneath the hood. It was all corroded so it was replaced. No problems since then.

SOURCE: anti theft will not reset

I got one of those cars. I feel your pain. If the security light keeps blinking it will not start.

First try the unlock sequence with the remote from outside the car... That fails try unlocking the drivers door with the orginal key and then try cranking. If the security light stays blinking your screwed.

Does the bus light come on?
