2001 Grand Prix. How do I clear tehe anti-theft security lockout?


The system only activates like this if there is a defect in the systems operation, you must have the security system scanned to see what is causing the unwanted activation. This is a dealer level repair.

"Starting Disabled Due to Security Problem." on my 1997 Cadillac Seville SLS. Please tell me exactly what to do to override this message and successively start my Cadillac?


your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.

Do you have a second key ?
Passlock™ System
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent is provided in order to prevent vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the powertrain control module (PCM)/vehicle control module (VCM). The message enables the fuel injectors.
The design of the Passlock™ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the PASS-Key® system. However, the Passlock™ system eliminates the need for a key mounted resistor pellet. The components of the Passlock™ system are as follows:
• The ignition lock cylinder
• The ignition switch
• The Passlock™ sensor
• The BCM
• The security telltale
• The VCM/PCM

Your best bet , take it to a qualified repair shop . Security light on - DTC'S - diagnostic trouble codes are stored . Having codes check would point in a diagnostic procedure to fix the issue .

Circuit Description
The Passlock™ system is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. The body control module (BCM) provides security system sensor power and low reference for the Passlock™ sensor. The BCM also measures the security system sensor voltage.
When the correct key is used to start the vehicle, a magnet on the lock cylinder passes close to the Passlock™ sensor within the ignition lock cylinder case. The magnet activates the security hall effect sensor in the Passlock™ sensor which completes a circuit from the security sensor signal circuit through a resistor to the security sensor low reference circuit. The resistance value will vary from vehicle to vehicle. The BCM will measure the voltage on the security sensor signal circuit and compare this voltage to a previously learned voltage. If the voltage measured is within the valid range, the BCM will send a class 2 message to the powertrain control module (PCM) to enable vehicle starting. If the voltage measured is not within the valid range, a class 2 message will be sent to the PCM to disable starting of the vehicle.

The center message said SECURITY now i have some problem for start the ignition, the battery can be in problems?


No, anti-theft system is activated. Try using a different key, if you have one. Your key may be wearing out. It has a resistor inside that tells the car you are not stealing the car.

2005 S40 wont start. Message says key error?


Do you have the remote, i.e. The deadlock system is activated and deactivated using the remote control key fob, which allows the driver to open the car as they approach. It seems you have activated the steering lock which is for preventing thieves to make a getaway. Use the remote to deactivate it and then try starting the car.......sodeep
P.S. The security system is a built-in feature of this model
