My steering column is locked and I cannot get the key to turn to start the car. I have a 2008 pontiac g5.

you ignition key has a chip in it and there is a chip in the ignition switch in the steering wheel. If either chip has gone defective you will get a shut down snd the anti theft message. If you have another key, try it. If you get the same message thern the problem is in the steering column. If you cannot check it or know how to repair it then have it brought to a reputable repair shop and have them check it out and if it is in the column, have them repair it.

Lock and unlock the drivers door with the door key. This resets the security system.

The reason your anti-theft is active is the new column has a different key than your original. The chip that is in the key is different than the one that is suppose to go to your vehicle. You need to order a new lock cylinder from your local GM dealer for your VIN number.

Hello: You might try tapping on the lock cylinder while turning and jiggling the key, if that don't work you will have to replace the lock cylinder.

typically your problem is in the column. That's for cars that have the shifter on the column. What's happening is the gears aren't lining up to put the shifter in the park position. Unless mechanically inclined you'll have to take into a shop.

Just encountered the same problem. Popped the clutch in first gear to kill the engine, but still cannot turn the car off.

Anyone have a clue as to why the ignition locked out?

Pry off the plastic cap off the bottom of the steering column. There is a small white plunger in this access hole and press while turning the key to the lock position.

actually, the most common problem for this is not the column, but the control arm bushings. they cost about 20 bucks a side. since almost every manufacturer has switched to this style of bushing, this is very common in every car that rolls into my shop. as for the steering column, i have never seen a problem with the actual column, but rather the intermediate steering shaft. now, that being said, these particular cars are now equipped with electrically controlled steering. you are inevitably going to get some noise as an electric motor changes direction and assist levels. you cannot get overly picky with an entry level car. think that noise is bad? try owning a newer toyota. you would swear the steering wheel is going to fall off in your hands.
