#130 of 1226 Key won't turn
Jul 05, 2007 (7:51 pm)
My 1999 Pontiac Grand Am is sitting in a NYC Garage, stuck because the key won't turn in the ignition. Will not budge at all. We cut the wheels back and forth. Nothing. Jiggled. Spoke gently. Spoke firmly. The meter is running and I will probably have to resort to extraordinary towing measures since we can't get the thing out of park. Does anyone have any advice. I am positive that the keys are mine. Any takers? I am fairly desperate. thanks all.

Why not simply replace the ignition? Then drive it to wherever?
I mean: Some of this is so obvious.
Your problem is not Passlock, perhaps can be rectified with a little silicone spray into the key hole. If you do have to replace the ignition, THEN you will need a locksmith who knows how to align and activate the new Passlock feature to your existing key.

I disabled my passlock by "cut the wire" method. It has worked fine, although (about once per month) the truck (99 Tahoe) will not start. It has the same characteristics (cranks, starts, you relase the key, then it dies right away).
Could the problem be an intermittent connection between the BCM and the PCM? I assume that even though the BCM is in a fault mode with the wire cut, it still sends the code to the PCM to allow the injectors to function. If thats the case I can look for the bad connection between the BCM and PCM.
Thanks for shedding light on this issue.

Took it in to the dealer this morning. I explained the problem to the guy at the counter and the guy who was going to do the actual work. They both agreed that it indeed sounded like a passlock issue.
I waited about an hour, and the counter guy came out. He said...and I hope I understood him right, because I am car stupid...that there is a passlock sensor inside of the ignition. He said they had one in stock, and had replaced mine. In retrospect, I don't know if that means that they replaced the entire ingition, or just the sensor.
There was no charge, and hopefully this has taken care of it. I run my business out of my house, and don't drive too much. My hopes are that if there are going to be any more issues of related to the security system that they happen before the warranty expires.

Dont worry Selena, you will be stranded again!
I've spent $1500 at the dealer, each time they replace something. It works for a while and the problem comes back. The real problem is an intermittent connection somewhere, my intermittent connection always occurs on hot humid days. The dealer take the car into their shop and by the time they replace a component, the intermittent connection goes away. The problem goes away and the dealer thinks they fixed the problem.
I'm stuck with mine, but if I had a new car under warrenty, I'd sell it back to the dealer and let them deal with it.

Thanks Selena for the update. And you got it right. The "book" way to fix it is to pull the entire ignition switch and replace it with one having a good Hall sensor. The entire switch is replaced, not just the sensor.
I hope that you won't have the problem again for some time.
But, I will have to second Mike's observation about humidity exacerbating the problem. My system tends to stick in the "off" position (as if I'd plugged in the toggle, but I haven't yet). At those times in the year when the weather shifts from dry to humid, the system can become reactivated intermittently, and that is when I have problems.
One of the worst times occurred when I accidentally left a window down a little and it rained. Both front seats got soaked, and while they dried out in a locked up car, the humidity activated the system and shut down the vehicle. But, as soon as all the water was forced out and dissipated, the car went back to behaving fine.

I guess that explains why those of us in the Southwest don't have much trouble with it. Hot and dry most of the year.

What exactly do you mean when you say the car starts but passlock shuts it down? If the passlock is tripped it won't start at all. Are you sure your not having a fuel pump problem? That sounds more like the symptoms of a weak and failing pump to me.
