this is the anti-theft system that has activated thinking the car was being tampered with. it will have to be reset. not sure if this is a problem with the BCM or the car keys have a problem. you may have to contact the dealer or a shop that can re-program this circuit.

Car dies when I use my remote start and press the lock or unlock button


This is most likely caused by the car's anti-theft system. Most newer cards require a separate module to be installed to override the anti-theft system while the remote start is in use. Otherwise, when the anti-theft system detects an anomaly, it will immobilize the vehicle.
DEI makes a 556H module for this purpose. The link shows the instrall manual for this device.

Absolutely! If the Passive Anti-Theft System (PATS) "thinks" you are trying to steal the car, it is SUPPOSED to keep it from starting. The problem is that the PATS thinks you are a car theif when you are not.
Below is a table straight out of the service manual for your vehicle. Please note that the FIRST action that must be taken for any PATS system malfunction is to scan the computer system for fault codes.

2002 malibu anti theft problem


With the car RUNNING cut the yellow wire to the ignition switch from the group of three wires.
Make sure the car is RUNNING when the wire is cut.
Tape the ends and thats it.....the car will start first time from now on....as long as you don't mind not having anti theft.

05 bmw x3 no start will not turn over battery good everything else works


If everything else checks out, I would look at the anti theft system. Your car has a factory installed anti theft system that also includes an ignition kill. I would have the system checked. Check your owners manual, there might be a chapter in it concerning the theft system.

Anti-theft system


Read your manual or take it to the dealer. It sounds like it needs reset.....if this is a factory anti theft system, only the installer may be able to help you.

Anti Theft Problem


Not much you can do without an expensive scanner and wiring schematics. You can check all electrical grounds for loose or corroded connections that includes the battery. Also check all fuses. Other then that you would need to take it into a shop. I wouldn't recommend a dealership because I feel there labor rates are to high and secondly the car is old enough that any half way decent shop should be able to fix or at least diagnose the problem. Hope this helps and good luck.

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.
