View Full Version : Passlock Lock system shut down I Need HELP!!!

A few days ago My 01' GA GT was t-boned on the passenger side. The damage was to the passenger door and a little bit of the rear panel and thats it. I drove it about 4 times since then. I was on my way home from work my car died the other night. I tried turning the key to the run position until the security light went off (15 minutes) then I turned the key all the way off nd then tried starting it again. This time nothing happened unlike in the past it started right up. I had it towed home. and they left it at the very end of my driveway. I took the front of the small s-10 pick up truck and slowly pushed it back from the road about 5 feet (if that) and as the car was moving backward all f the dash lights went out except for the engine light. Now when I try turning the car over it does absolutely nothing. Somehow the system has locked me out and I cannot do anything. Are their sensor switches anywhere on this car that I need to reboot so that I can get my car running again? I called the service dept at the pontiac dealer and he was stumped. I do not have remote start on this vehicle. I have no clue on what to do from here. I have even tried unhooking the brand new battery and hooking it up again. I NEED to get this running and to my fathers garage so we can get her fixed and back on the road and looking awesome again before summer. Please HELP!!!

Yes I have have had issues before bt nothing like completely shutting me out of the system. Before the car would still try and turn over but now when I try and turn it over nothing happens at all. Before I would turn the key on to run without trying to start until the security light would go off. I then would turn the key all the way off then I would try and start it with success.

When I was hit it didn't do anything to my ignition. Only the passenger door was smashed in above the frame and a little bit of the rear panel a foot in front of my right tire. It was driven the rest of that day and then next day before stalling out on the side of the road.

I am going to the dealership in the morning to order a new key. I can't imagin that inserting the key will reboot the security system and make everything wonderful again. A while back I had a Escort GT that had a fuel sensor in the rear and it was defective and leave me stranded as well. Is it possible there is a fuel sensor in these Grand Am's? :banghead

try this


In the event that your vehicle fails to start after installing the DHP 1.0 PCM, you will need to perform the Security Relearn Procedure. This procedure allows the PCM to function properly in your vehicle. Follow the steps listed below completely.

1 Attempt to start the car by turning the key to the Start/Run Position.
2 Observe that the vehicle fails to start and that the security light is illuminated.
3 Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'off' position.)
4 Allow the vehicle to sit with the key in the 'ON/Accessory' Position for no less than 11 minutes.
5 Turn key to off position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.
6 Repeat #1 - #5 for 3 cycles.
7 On 4th attempt, car should start.
NOTE : Since this is a fairly long procedure, I would limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.

NOTE 2 : It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time. I.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.

Properly executed, this procedure should take approximately 35 minutes to complete.

Thank you Metallman but as I said before in my thread starter that used to work. Now the car doesn't crank at all. It is as if the battery has been disconnected altogether when in fact it isn't. I checked all of that + went and bought a brand new battery for the vehicle. The car is completely dead! The dash board lights are all out except for the check engine light.

Let me ask another question. Does the passlock key have a chip on it that you can visually see? Because looking at the key I have, that was given to me when I bought the car three years ago, it looks like a normal key.

It could be a starter solenoid, that would not allow the engine to crank.......

there isn't a "chip" that can be seen, It looks like a normal key
