Saturn Security System - Have Lost all Vehicle Power

1. check fuses
2. make sure all wired cables to PCM/BCM and security modules are seated.
3. scan it.
4. car came new with 2 keys both fail? or lost the spare(oops)

During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for

longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-e
viced as soon as possible (comment scan it)

Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.
?€¢
To disarm the CTD system in arm pending mode, SECURITY indicator flashing and doors open, perform 1 of the following:

-
Press the UNLOCK button on the keyless entry transmitter.

-
Insert a valid key into the ignition and start the vehicle.

?€¢
To disarm the CTD system in the armed mode:

-
Press the UNLOCK button on the keyless entry transmitter.

-
Insert a valid key into the ignition and start the vehicle.

?€¢
To disarm the CTD system when activated, alarming mode.

-
Press the UNLOCK button on the keyless entry transmitter.

-
Insert a valid key into the ignition and start the vehicle.

Security system failure is a common problem on GM vehicles. Every time you put your key in the ignition, the vehicle's security system reads the signal from your key to make sure it is OK to run. When it receives the "correct key" signal, the security system allows the starter to turn over, and/or the fuel injectors to function and your car works like it normally does every day. If you were to use a different key, or try to hot wire it, the system would shut down these parts of your car, thus making the vehicle completely immobile. This is GM's way of preventing vehicle theft. The problem is that the system is known to fail quite commonly. It has been failing consistently for around 30 years. When it fails, two things can happen. First, you turn the key and nothing happens at all. Lights work, radio works, windows work... just not the starter that you need to start the vehicle. This is a "starter immobilizer". Second, you turn the key and the vehicles starts just fine, but then stalls in 2-5 seconds. This is a "fuel immobilizer". It literally cuts off the fuel injectors and stalls the vehicle to immobilize it. These are normally, but not always followed by a light on the dash that says SECURITY or ANTITHEFT. These lights are to inform you of the system's failure to collect the information it needs from your key to the computer. If your security/antitheft light is on, odds are you will be stranded soon, if not already. Remember that the security system controls the security light. If the system is failing, the light may never warn you of the failure. http://vatspasslockpasskeysecurityhelp.yolasite.com/

You lost power to the security module and it now needs a "relearn" performed. Make sure the battery stays connected for this relearn.

Turn the ignition to the "on" position and verify that the theft light is on or blinking. Then leave the key on for at least 30 minutes without disturbing the vehicle. After 30 minutes come back to vehicle and observe the theft light. Should be on steady or off. Do not turn the key off, move it from "run" to "start" and attempt to start vehicle. Engine should start and run if system was successfully relearned.

Take state issued i.d. such as drivers license or i.d. card and registration card or the VIN number to any dealership and they can make key using the VIN ( Vehicle identification number) i had 2 do that twice and it was only $10.00 sounds hard 2 believe but it works. Hope this helps you 2.

Lot's of warning lights , check engine and all the others , You should have the vehicle checked for DTC'S - diagnostic trouble codes . Lost power codes probably ! Could be a number of thing's ,ignition switch , BCM - body control module just to name a couple . DTC'S will point in the right diagnostic direction . The electronic's on your vehicle Are complex to say the least .
The body control system consists of the body control module (BCM), communications, and various input and outputs. Some inputs, outputs and messages require other modules to interact with the BCM. The BCM also has discrete input and output terminals to control the vehicle body functions. The BCM is wired to the GMLAN High speed serial data buss and the GMLAN Low speed serial data buss and acts as a gateway between them. If the BCM does not communicate the vehicle will not start due to the inability of the engine/powertrain control module (ECM/PCM) and vehicle theft deterrent (VTD) control module to communicate without the BCM providing the gateway function.
Power Mode Master
This vehicles BCM functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions.
This is something you should have checked out by a qualified repair shop .

GM vehicles are notorious for a a having a failed antitheft system thats called Passlock. When this system fails, the key doesnt communicate with the ignition correctly and causes the vehicle to stall. Next time this happens, look for a light on the dash that says SECURITY, if you see this, then this is the problem. Go to this link for info and DO IT YOURSELF solutions to this problem.

The security system will not allow the vehicle to run with the proper key.You will need to purchase a key.

PWR STR message
Power Steering: Refer to Power Steering System Description and Operation in Power Steering System

The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

Having a qualified repair shop check it out would be your best bet ! Do you know what DTC'S are ? diagnostic trouble codes
