The battery warning and anti theft light comes on and the car goes dead.

I have a 2006 pontiac g6. First the battery warning light came on. Shorlty thereafter the anti-theft light came on and my power steering stopped working. Following this the engine went dead. I was unable to crank it without jumping the battery off. Once jumped, the same sequence of events occurred. I removed the battery and the altenator and had them checked. Both are working properly. Is this a problem with the computer or do I have a wiring issue?

Check your voltage before jumping to the conclusion of a bigger issue. Get yourself an inexpensive multimeter/voltage tester and set it to 12v d.c.
1. Check voltage of just battery. Should be around 12 to 12.5 volts if its ok
2. Turn the car on, check voltage again, it should be 13 or more volts

If #1 is not happening, charge the battery overnight.
If you have a good charge and #2 is 12v or below, your alternator is shot, or you could have a corroded ground, loose ground, or something is just not making a connection.

If your battery keeps going dead after this, something is making a connection when it shouldn't and you have a slow electrical leak. If that's the case, start reading about how to check for voltage leaks in a car.

SOURCE: Engine Seized up on a 2006 Pontiac G6

check the oil and coolant levels. if coolant is low pull the sparkplugs and try to turn the engine over if still not turning free remove the serpentine belt and try again, if it turns over ok check the pullyes on the front of the motor to see if they all turn free by hand. a serpentine belt can prevent an engine from turning over if a tensioner, idler, water pump, alternator, or power steering pump is siezed up or starting to seize. being your battery is bad I'm thinking probably the alternator is seized. hope this helps mike.

SOURCE: 2006 Pontiac G6 electrical power steering problems

The electrical steering system on the vehicle had a common problem with early failure caused by a sensor in the steering column. The correction is replacement of the steering column.

#10183: Special Coverage Adjustment may apply to your vehicle if it has under 100,000 miles on it.

2006 Pontiac G6 anti theft triggered. A locksmith made a new key car, but cranks no start.

You probably need to do a key relearn procedure. Turn the key to the ON position for 15-20 minutes until the security light goes out. Then turn the key off and back on again until the security light goes out. You need to repeat this 3 times, then once again turn the key off and back on, this time the security light should light and go out after its 3 second check. Now the car should start normally.

2008 pontiac g6 stuck in anti theft mode & only can jump start with new key

You do not have a problem with the anti-theft system , if the vehicle starts when you get a jump, you have a battery or charging system problem. It is not stuck in anti theft mode ??? Your best bet lady , take it to a qualified repair shop .

I have a 2010 Pontiac G6 the anti lock keeps coming on but I can still start my car and drive it. How do I get the anti lock off? I mean it’s my car and I have the key for it every time I drive ??

Anti-Lock BRAKES, or Anti THEFT system?

Antilock brakes (ABS) you need a garage.

Anti-theft system, are you using the key you have always used. A Valet key only open doors. If the anti-theft light comes on and you can still drive it, you need an auto-electrician or a new vehicle.

Anti theft 06 Pontiac g6 how to reset

It seems like you need to reprogram your key, and this is how you can do it:
1. Sit in your car and ensure all doors are closed
2. Put the key into the ignition while holding the lock button on the driver's door
3. Turn the G6 key in your ignition from "On" to "Off" while holding the "Lock" button, and do two more cycles of "On" and "Off" in quick succession.
4. Release the ock button and press and hold the lock button on the remote for 15 seconds
5. Now, remove the key from the ignition, and it should be programmed, and anti-theft mode would be put to rest

My 2008 pontiac g6 will not start when i put the key in the ignition the anti-theft light or w/e is coming on blinking. help please thanks

If you key has a chip in it there is a chance it may be damaged. If it doesnt the turn key assembly may have gone bad. I would recommend you take it to your nearest Pontiac dealer and let them look at it. Because if its the key you will have to take it to the dealer to get a new one and if its the key assembly you could get the part cheaper at autozone or someplace like that but you will still have to take the car to dealer to have them reprogram the computer for the new assembly.

Radio

I assume your audio system has anti theft.. You have to enter a code to restore operation of radio... But first check the fuse for the radio..If you dont know the code and are not original owner you will need to remove the radio and locate the model and serial number and then call the dealer to obtain code.... Be warned they might want to charge you ...Good Luck
