Question about 2002 Pontiac Grand Am

My 2002 Grand am is have a passlock problem. The

My 2002 Grand am is have a passlock problem. The security light started flashing and would not let the car start. I did the reset per the manual and it started both times. Now the security light stays on. I am able to start it without any problem but the light stays on. I have tried a few thing such as cutting the yellow wire while the car is running. I also tried soldering in a resistor between the yellow and black wire but neither helped.

I discovered the hard way- ($85.00 later) Step 1: turn key to "on" position. step 2: open driver door. (security light should be flashing on and off) step 3: wait ten minutes with key in "on position and driver door open. step 4: when 10 minutes is up-(youll know-because security light will have stoped flashing after 10 minutes) close driver door ,turn key to "off" position, then turn key "on" to start. drives me crazy!! I have to do it to mine sometimes 2-5 times a day! GM doesnt have a fuel reset button etc. like fords do.

Dear friend-cutting the wiring is not a good idea,i suggest you do a diagnostic check and work from there.if you disconnect the battery for a while then reconnect,the light should go off.

2002 suburban start and dies, its not the fuel pump. what is it


Is there a security lamp on the dash that is on or flashing? Any applicable trouble codes? My info shows you have passlock, usually a fuel injector disable, only, may start and stall. If vehicle starts and stalls, leave key in the on position, If security lamp does not flash, the passlock system should not be at fault.

How can I bypass the security code


Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)

You have now experienced GM's terrible anti theft security system. These systems are known for failing and will cost you an arm and a leg to fix. Anywhere from $350 - $700 plus labor. Most mechanics wont even touch these "PASSkey" security systems.You'll have to go to a Dealer mechanic. The good news is that you can bypass these systems permanently. And you're vehicle is one of these lucky ones that CAN be bypassed. This link should help you find what you need and help inform you of how this system works.

Security light flashes,and car want start,except bye the starter,and suddenly stops.


Depending on the year of vehicle how the security system works (you didn`t specify year or model). Older models up to 1997 use passlock I, they have a chip in the shaft of the key, and usually break in the steering column just behind the ignition key cylinder. You will need to know the code number of the key, and will have to order a new ignition cylinder and new keys. After 1997 its passlock II which has the chip inside the head of the key. It learns the code of the key and ensures its the correct key every time you start the car. The most likely problem with this system is the passlock sensor in the ignition switch. Try turning key to run (do not crank) leave key on for 10 minutes, the security light should be flashing. When it stops flashing or goes solid (after 10 min relearn) try to start again. If starts you will need the passlock sensor soon. It probably has a trouble code set in the BCM (body control computer).

My 2002 Grand Am will not start, when ignition is turned on nothing happens with the starter, not even a sound from the starter, everything else works. I took off the starter and had it checked and it...


I have a 2002 Grand Am also. I had this same problem twice. The first time it happened, the battery was still working but was not strong enough to crank the car or make any noise under the hood at all. All electrical stuff worked though (lights, radio, etc). So i bought a new battery and everything was back to normal.

The 2nd time this happened, the passlock system was shot (the passlock system is a type of security device the car has installed in it.) When i inserted the key, everything worked, but nothing coming from the engine. I had to take the car to a dealership and get it replaced for around $400. If you look online you can find other ways to avoid the dealership and fix it yourself, but that could result in making something else not work as well.

Hope this helps in some way.

Security light flashing and not allowing start of car. Passlock problem.


It is your locks. I would just disconnect them and lock the car manually. Its a common problem on most GM cars cause water got in an rusted the auto lock motor cause them to send the wrong signal to the computer.
