Theft lock 2005 Cobalt

I have a 2005 Chevrolet Cobalt, I had to replace the Body Control Module as it got wet and shorted out. (Light flood) The radio is locked which is one problem, but the biggest issue is that I believe that the Theft Lock feature will not allow the car to start. Everything other that the radio works fine, the ignition seems to work fine, but when I turn the key to start the car, it does not crank and the security lock light comes on in the dash. The battery is fully charged, and I can jump across the starter and the engine will crank fine. It might have been a mistake, but I tried using a remote start button on the starter while the key was on, the engine would start run about 10 seconds and die.

Any ideas??

If the BCM has been replaced, the BCM has to be reprogrammed by a dealer as it control many car functions.

If I lock my 2006 Chevy Cobalt, the security system will randomly lock and unlock the doors accompanied with the horn honking


I think you have a BCM - body control module problem ! The BCM controls the automatic door locks .
Automatic Door Lock Operation
This BCM controlled feature can be personalized to driver preference. Refer to Power Door Systems Connector End Views Personalization Description and Operation in Personalization.
The BCM will automatically lock the vehicle doors if the following conditions exist:
?€¢
All vehicles doors are closed.


?€¢
The ignition is in the ON position.


?€¢
The vehicle is shifted out of PARK.

The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
The
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.

My battery died so i replaced it and now my radio won't come on. Tried holding down power button, turning on and off ignition. Still has no power. the battery was out of the car for about 4 hours.


If your radio has anti-theft system you will have to go to the dealer and get the accss code to reactivate the radio if you dont have the code already. GM vehicles with anti-theft radios will lock when power is lost to the system if the radio is not turned off prior to battery disconnect or dying.

The word "lockout" lights up on the radio. the


Sounds like you may need a Body Control Module. It's not a radio code or the radio would say "CODE" And because the dome lights dont work and the trunk unlock quit working, a Body Control Module sounds reasonable. You have to get them new because they are VIN specific and might possibly have to do a Theft re-learn after installation. Junkyard parts will not do or you will have more problems than you have now.

How do I set the anti theft light in my newly purchased 2006 chevy cobalt-I have manual locks and don't understand how you would set it.


If the light is on it means you have a security concern and will need a scan tool to find out the code.You will need a gm scan tool or one that can read body contol module/theft module data.

Security button to resetm pass key is located where?


your vehicle is equipped with Personal Automotive Security System (PASS-Key II(R)).
This security system is designed to prevent vehicle theft by disabling fuel system and starter unless an ignition key with a specific electrical resistance is used in the ignition key lock cylinder. PASS-Key II(R) system operates using sensing contacts, which are located in the ignition key lock cylinder. These contact a resistor pellet located in the ignition key. When lock is rotated, battery voltage is applied through appropriate fuse and resistor pellet to theft deterrent module (except Century), or body control module (Century). Pellet resistance is then compared with programmed value in the theft deterrent module or Body Control Module (BCM).
System components include ignition key, ignition key lock cylinder, theft deterrent module (except Century) or BCM (Century), theft deterrent relay and Powertrain Control Module (PCM). The PASS-Key II(R) system can also be supplied as a special equipment option on some vehicles

It will reset itself after about 10 minutes. You just have to wait until you hear a click and the pass key light goes off.
Be sure to clean the little metal strip on your key while you're waiting...

Would anti theft cause car to quit


Sounds like a bad ignition switch have ur body control module checked for codes if u have a B2960 and or B3033 then replace the ignition switch.

SECURITY
If your vehicle has the remote keyless entry system, this feature allows you to select the method used to arm the vehicle's security system. When SECURITY appears on the display, press the reset button to scroll through the available settings:
* RKE (Remote Keyless Entry) (default): The content theft-deterrent system will arm when the lock button on the remote keyless entry transmitter is pressed or when the power door lock switch is pressed.

* PASSIVE: The content theft-deterrent system will arm itself 60 seconds after the ignition has been turned off and all of the doors have been closed.
