Question about 2000 Pontiac Grand Am GT

1 Answer

2000 Pontiac Grand Am -- Security light/Passlock -- Engine turns over but won't start & the security light flashes. This has happened twice in the last 3 months. Do anyone know if this type of problem usually gets more frequent. And what component typically causes this problem? We read the manual and learned we could reset by turning to on and waiting 10 minutes. This worked but we are wondering if there is a way to bypass or disable the passlock system to avoid it happening again? Thanks

There is a way to bypass the system we do it often but you will need to buy a data bypass unit to install in order to bypass the passlock sensor in the dash. Once the unit is installed, it is turned on by inserting the key into ignition, then the unit will send the proper code to the BCM allowing it to unlock the ECM and then car will start.

My grand am turns over, but wont start. I was low on gas, but have added 4 gallons since then. still won't start! what could it be?


no it will not start because it is a passlock problem with this car... your security will blink and you have to leave the car in the start position with the key in for 10 min until the security light stops flashing, turn the car off and then restart it and it should work , till next time it happens, which by the way , with mine it was like 2 -3 times a week, finally i got tired of this and wen to a mechanic friend who disabled the passlock system , best decision i ever made, cost me 40.00, unlike the 500 i was quoted to change the ignition module from dealer... so do not waste your money it willl not fix this problem i have heard anyway.... so good luck

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.

Not starting


It was the security Passlock system on my car as well. I did't notice that the security light had come on the first time. Look up Passlock in the owners manual.
  1. You can reset it yourself for free by turning the key to accessory position
  2. Leave for ten minutes on accessory mode.
  3. Turn car off completely
  4. Try to restart.
This fixed my problem on my own after I paid to have it fixed and it happened again the next day.
