2003 Pontiac Grand Am Ignition switch issue
« on: July 08, 2005, 08:41:40 PM »
I have a 2003 Pontiac Grand Am and recently experienced a issue with the ignition switch. When attempting to start the car (turn key) the motor wouldn't turn over, all other electrical worked. A local mechanic said the security system was activated and wasn't reconizing the key, so I got an orginal key and still no go. I called our local GM dealer and he explained that the key and switch would have to be reprogramed. After a tow bill and a half a days labor he explained that it wasn't the keys that they didn't have a sensor in the key on this car. He said that they would have to hook it up to the computer and get a code to tell them the problem. After about a hour and a half of analyzing the system they still didn't seem to sure. Said it needed a (pass lock sensor) at about 400.00 to replace. Well after all this the ignation switch started to work again. But they explained that this is only temporary and not to trust it. They also explained that some times that sensor will start to read the key again and work, I also wonder how it reads a key that as they also explained has no sensor in it.
I'd be curious to hear another analagy of this whole think.  Rolling Eyes

the sensor is part of the lock cylinder,they are correct when they say it will happen again.our shop will usually replace the lock cylinder and ignition switch,perform the reprogram and havent had any return with the problem.

Thanks for the response. I guess I'm a little confused when they say it needs to read the key. What does it read on the key, they don't have a sensor chip or anything in them. The dealer thought they did, but when they tried to read them with a scan tool they found that they didn't.
How common of a issue is this ?. Since this happened to me just a short time ago I've talked to 2 o3 other who have had the same issue. Rolling Eyes

Have you looked in the back of owners manual?  I know the customer service phone number is there.

After much research I found that this switch issue doesn't take rocket scientist to understand and it's getting more and more an issue on the GM vehicles the size class of the Grand Am.  After talking to other folks who have experienced the problem, replacing the switch and sensor may not be the final fix. That some experienced multiple failures. What GM doesn't tell you is, if it happens to you. It's not to difficult to get it running again to avoid a tow. If you turn on the ignition switch and leave it on for ten minutes, you can fool the computer and it will clear out the problem and the car will start. I had a GM mechanic tell on the hush hush that if it happens again, this will get it started. This was after I paid them 50 bucks for a tow to the shop.  Exclamation

Just wondered if the trick worked to get your car started. That's how they started my car at the dealership after I paid a tow to get it to them. 10 mins and started right up. Wish I had know that before the tow bill. Oh'well. Wink

The ten minute learn procedure may not work if the pass lock sensor is shot in the lock cylinder.  You may have gotten lucky because the pass lock system was timed out for 10 minutes and happened to be able to read from the sensor on the next ignition cycle after the timer expired.  You can't fool the computer.  It either gets the signal from the pass lock sensor or it doesn't.  You just got lucky.

Closed due to thread being old and no feedback.
