My 1996 Pontiac Grand Am Se's anti-theft system thought I was a thief.
 

My 1996 Grand Am Se anti-theft system was not allowing me to start the car at 134,178 miles.  I took it to a Chevrolet dealer.  Their ddiagnosis of code P1629, set-theft system ignition cylinder failed, led them to replace, recode, and program the cylinder at a cost of $706.55.

Then, ten months later, at 138,459 miles, I had to have car towed back to dealer.  The theft system again prevented starting and the tow cost $132.00.

They told me to replace the faulty PassLock cylinder and code keys to the cylinder and program the PassLock system at a cost of $94.88.

Now two weeks later, the car is not starting thanks to its anti-theft system again.  I am going to have to have it towed back to dealer.

The manual gave me the solution.

Turn the key to "on" and wait till the "security" light goes off.

It takes about 10 minutes.

Then turn the key to "off" and it starts right up.

I also have a 1996 Grand Am and also have the same trouble It starts and shuts right off.

I let it sit in on for about 10 minutes and it starts, but I have not found a way to fix all together yet.

It is a very big pain but it runs and have no money for a new car.

I have a 1996 Pontiac Grand Am with similar problem.

Everyone said it was from my command start system. That is usually when it happens. But it has happened once when starting with the key.

Usually I just have to wait 10 minutes and then it will start.

If the car turns on and starts then dies in a couple seconds, turn key on and start till engine dies and leave key on run position for ten minutes repeat this 3 times on third time car should stay running.

There are 3 small wires coming from the switch 1 white 1 black and 1 yellow.

After three times with key on and car running cut and tape the small YELLOW wire and car will start every time but the anti-theft light will remain on but you will be riding.

The 3 wires look kind of like a ribbon connection on a computer. They are on the right side of column. It is pretty simple once you do it.

The only thing is it will cause anti-theft light to remain on, so keep it locked at night.

Hope you well with this it does work and is pretty simple.

Good luck.

Wow! I didn't realize so many people have the same problem as me. My 1996 Grand Am has the same problem. I've had the code reset 6 times!!!!!

It will start and one month later it won't.

I took it to a dealer and they told me I had to replace the instrument cluster.

There's obviously a problem with 1996 Pontiac Grand Am. It's pretty ridiculous!

I almost just want to sell it so I don't have to deal with it anymore.

It has been in the shop, combined, for about 6 weeks (all different times, but for the same reason).

They have changed keys and even installed a new computer. It still won't start at times.

Really upset, but can't afford a car payment.

My next car won't be from Ford.

I have a 2003 Grand Am and have had the same problem. I read online to turn the key to on and leave it for 10 to 12 minutes.

Then turn off take key out and then start car.

It is worth a try.

I have had to do it twice now but it worked.

I have a 1996 Grand AM and it did the same thing to me, but I didn't have the money to take it to a dealer.

I think I might have a solution it might work and it might not.

Try replacing the ignition tumbler set by yourself. After that put the car on a trickle charger for the battery.

Turn the key to on -- not start, but on.

Your instruments will come on, but that's what you want.

Leave it on for at least 35 minutes to an hour. DO NOT turn the key off. Now try to start the car. If it works, it usually lasts for awhile; if not there is a relay mounted on the engine side of the radiator driver side -- replace it.

This works sometimes. Just give it a try and make sure you disconnect the air bag before you do anything.

Hope this helps you. It did work for me.
