SOURCE: how do you reset the anti theft system
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!
