Question about 2008 Pontiac Vibe
The theft detterent appears to be disabled. Is there a fuse in this system? If so, where is it? Can you turn the system off and on? I followed the owner manual instruction and the security light does not come on and the alarm will not work with the window down and opened from the inside?
The security 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.

These cars had a tendency to "lose" the password for the theft deterrent system. Your body control module doesnt understand your key, therefore tells your pcm to discountinue fuel supply. To reprogram the system, start the engine and let it stall. Leave the key in the run position. The theft light should flash for 10 minutes. When the light stops flashing, Turn the ignition off for 10 seconds. Turn the ignition back to the run position. This procedure tells the BCM that on the next ignition cycle, to accept the new password. Now, it should start. If not, it may require the clearing of the code, and possibly the reprogramming of the PCM, which needs to be done with a dealer scan tool or equivilant.

1st the system alarm is intagrated into the engine control electronics, it can not be disabled without poss damage to ther systems and controls, 2nd the most common cause of your issue is the sensor in the ignition lock cylinder being defective, this is the most common issue on all GM anti-theft systems.

If the ignition lock has not been damaged, ( that's where the GM Passlock system reads the ignition key) here is how you reset the Passlock to youe keys.
Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.
Good luck and keep me posted, be glad to know you got your car running again.

The security light is a indicator that one of the parts of the antitheft system is failing, this then disables parts of the car due to the antitheft thinking that the car is being stolen. You may have broken something while turning the ignition when trying to learn your key fob. Did you make sure to pull the radio fuse before trying the key fob process? A lot of GM's 2000 to 2004ish ran the antitheft thru the radio. Its really hard to tell. Here is a link that explains the anti theft system. A lot of information and some ways to get around the system. 2. Remove RADIO fuse from fuse box. Fuse will be number 17 and located at LH side of instrument panel.
Here is what i found for reprogramming your key fob remote
1. Be sure ignition is OFF.
3. Turn ignition from OFF to RUN 3 times within 5 seconds ending in the RUN position. Off is the position where you can remove your key and Run is the position shy of starting your vehicle (do not crank engine or start vehicle). Be sure you are turning the key from off to run quickly.
4. Doors will Lock and Unlock indicating entry into programming mode.
5. Hold Lock and Unlock at the same time on first remote for approximately 15 seconds. Vehicle will respond by locking and unlocking doors indicating successful programming.
6. Repeat step 5 for each additional remote including working remotes.
7. Switch ignition off. Replace RADIO fuse. Test all remotes.
2. Remove RADIO fuse from fuse box. Fuse will be number 17 and located at LH side of instrument panel.
