You can't. Unless you're an electrical engineer. But at best all you can do is bypass the key. But the car has to be functional to do this. If you can't duplicate the signals, you can't build it. Passlock III is a pain to bypass.
The antitheft picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.
This is a known problem with the power steering which will probably
require replacement of the power steering motor. The HHR uses an
electric 12V DC motor to provide the power steering force, and they have
GM is recalling the Cobalt and other vehicles for this issue, but not
yet the HHR. If you are out of warranty, you will probably be
personally responsible for the cost of diagnostics and replacement.
You will probably need to contact your dealer unless you are able to
replace the motor yourself. Sorry.
Mildred, no matter what type of vehicle were talking about when it comes to dying issues it can be a lot of things causing the problem. If the problem occurs when you come to a stop it could be the "IDLE AIR CONTROL" OR on some vehicles the "EGR VALVE". If the problem occurs while driving done the road it could be wiring problems or connector issues, fuel pump issues, Cam or Crank Sensor issues. Engine Controller issues. You can try tapping on the idle air solenoid and see if the engine raves up and you can also perform a wiring wiggle test on all the wiring with the engine running and see if it dies. You can also tap on the fuel tank and see if it dies. These are a few things you can try to find what the problem is. As you see Mildred, when you get into dying issues it can be very difficult to find the problem. Hope this helps and have an awesome day Mildred.
First thing to check is if you're battery is charged. If it is, check the oil to see if you have oil in the engine that you didn't run the engine tight. Also, you have to check if you're getting power to the starter. With the description you're giving of the problem, it could be a number of things. Very hard to diagnose with the description you're giving.
