Theft deterrent system car won't start
I tried to start my car this morning my theft
deterrent light is on I tried to unplug the battery left
key in ignition. Please help.
You just aggravated the problem by disconnecting the battery. Now most likely you will windup at the dealership getting the system re-flashed, you cannot remove main power without hooking up a preset saver tool or computer programming can be compromised.
