Hello! Unfortunately, you are experiencing a common issue with many Grand Am owners. The problem is that you have a defective PassLock sensor. When the sensor doesn't "close" when you turn the ignition, it detects a fault and will not start. If you leave the ignition in the "On" position for 10 minutes, it will reset and allow you to start the vehicle. The ignition cylinder contains the sensor, and this part is roughly $400 and not particularly easy to replace.
There are however, bypass methods available that will disable the PassLock feature entirely. I have included a link to the instructions here.
NOTE: Be aware that some of the bypass options will disable your PassLock anti theft system ENTIRELY. I recommend utilizing one of the options that explicitly states that your system will be fully operational after modification (toggle switch method, for instance)

Hope this helps and good luck! Thanks for using FixYa!

You have a security issue going on. Try turning the key to the on position and leave it on without trying to start the car. Wait about 10 minutes and the light will stop flashing and come one solid. Then try to start the car. Turn the key to the off position. Wait 60 seconds and then turn the key to the on position. See if the light is still flashing. If it is then try the process again. If it isn't flashing and it is on solid then start your car.

Starting: car will not start; dash reads "starting


Hello, RW Betton,

Here is a few things to try then please read toward the bottom. Please read my whole page here of ideas for you.

Question? when it does disable it usually will say " starting disabled due to theft system remove key from ignition and wait 3 minutes'. Are you able to start car after the 3 minutes? or it wont period? My car does this a lot to but I think its cause you have to unlock the car, get in it, shut the doors and then start the car because mine does it when i open the doors.

Also some times if you have a chip in your key will do this as they ware out, and would have to try you back up key (if you have one) and if turns out to be your key, that has bad chip, dealer would have to replace that.

Finally, this is your other choice as well below, and you can click on that site and it should help you. Most the times this whole issue is triggered from the key itself into the ignition, that cause this.

If you have the GM pass lock system in that car, this is a site that will show you how to disable it:

tml


However, if it were my car I would see what the dealer will charge to fix it first. It may just be a simple reprogramming is needed or a inched wire in the steering column. I would want the car to have an anti theft system working as it should.

I hope my free advice has helped you, and if you could please rate my help accordingly and some kind words too. I appreciate it, and keep me informed on progress. Here is also my direct link for all my services I offer to help you.

There is no way to disable the immobilizer ( that would defeat the purpose of it ), the question I have, do you have another RFID tag on the ring with the truck key ( speed pass, another Ford key, etc ) ?

If you have these on the same ring, and they are too close to the key cylinder, it can cause a false negative for the programmed keys.

Have you tried another key ?

Are there any other modifications to the truck ( remote start, or security system ) ?

Starter disabled due to security system


The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start.
Cheap fix:
----- http://vats.likeabigdog.com/
----- Bypassing the key
Never worry again fix:
----- http://newrockies.ca?ap_id=judd0081
----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

Normally, you would insert the key in the drivers door, turn left, then right to disarm and reset it. If yours is malfunctioning, you can disable it for good by doing the following:

The FACTORY ALARM DISARM WIRE IS
light green with a negative polarity at the harness coming out of the door in the driver's side kick panel.

Once Located, splice into this wire with a similar guage wire, and put it to a solid chassis ground. This terminates the OEM alarm functions entirely.

OR:

Bulb Stays Illuminated and Engine Does Not Start. If the "SECURITY" indicator stays illuminated while and after attempting to start the engine and the engine does not crank or start, this indicates that the PASS-Key II module has sensed an improper key value and has disabled the engine and set the disable timer. This specifically does not mean that the key sense circuit is open or shorted to chassis ground, refer to "Bulb Flashes and Engine Does Not Start." Remove the key from the ignition and verify that is the correct key code for the vehicle. The key code may be checked using J 35628-A and comparing the key code to that of other keys for the vehicle. After waiting approximately 3 minutes for the disable time to expire and the "SECURITY" indicator to go out, try to start the engine with a known good key with the proper key code.


Bulb Flashes and Engine Does Not Start. If the "SECURITY" indicator flashes once per second and the engine does not start, this indicates that the PASS-Key II module sensed an open, a short or otherwise invalid (value matched none of the available 15 key codes) input from the ignition key resistor input. The PASS-Key II module does not start the disable timer during this operation mode. This operation mode could also be caused by a malfunctioning power or ground circuits.

OR:

There is 2 more ways to fix the problem:

1) replace key cylinder (very difficult)

2) look for 2 small white wires encased in an orange cover at the bottom of the steering column at the big steering column connector. Cut the two small white wires and connect a resistor of the same resistance of your key chip onto the two white wires leading into the connector. Problem solved!

Security light flashing


Take the Original Ignition key out to the car. Get in it and turn the key on. Every light should light up like your going to start it. The factory security light will flash. Leave the ignition on until it stops flashing. Should take about 10-15 min to do it. once it does, shut the key off and then turn it over to start the car.
