Question about 2002 Pontiac Grand Am

2002 Grand Am no start condition

Thanks for the response. After further research we found the method to reset the passlock by turning the key on for 10 minutes. This allowed the car to start and run normally. What we do not know is what caused this and what do we do to prevent it from happening again. If you have anything to add that would be great.

    car will not start hear a slight clicking radio and lights work

  • Anonymous Aug 05, 2008

    I have been having problems with my Grand Am not starting and when it does, the security light is on. I know I can reset it by turing the key on for about 10 min. This seems to be a very common problem, but I can not find the solution to keep it from happening.

The passlock system is sensitive to voltages on the circuit. Make sure all your power and grounds are clean and tight. Make sure you car battery at 100%. Check the connector at the pass lock sensor in the steering column is good. Alot of time just by unplugging and plugging the connectors solve the conceern. If all are good, I would wait to see if it happens again. Then I would change the ignition cylinder. I would not recommend it if your not familair with coding cylinders. What you did is relearn the passlock voltage reading the computer sees when you first turn the key.

When the ignition key is used to turn the ignition lock cylinder to crank, start, a magnet on the lock cylinder passes close to the Passlock™ sensor within the ignition lock cylinder case. The magnet activates the security hall effect sensor in the Passlock™ sensor which completes a circuit from the security sensor signal circuit through a resistor to the security sensor low reference circuit. The resistance value will vary from vehicle to vehicle.

My 2002 Pontiac grand am will turn over but will not start

You may have an issue with the Passlock Security system. If the key security code is not read when the key is inserted, the Passlock system de-activates the fuel pump. Many GM vehicles are on a recall list at this time due to such problems. The earlier models started about 2001 and goes to about 2009. Other possible problems could be ...No fuel in the tank, a bad fuel pump, or even a bad ignition module. Check the things you can check, and for the others you will need a mechanic. Best Wishes

How can i unlock security code on a 2002 grand am without the oringinal key so that i can start my car.

Try this process. If this does not work. You may have a key or a passlock issue.
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key

Instruction on how to eset passlock on 02 grand am 2.2l

Just have a look at this: - I saved my car with this. I had a Passkey system, but the only difference between PassLock (yours) and PassKey is that the former has a resistor in the lock, while the latest has it in the key. For the rest, they are the exact same system. I also heard several other people with a PassLock system using this method successfully.

How do you reset passlock 2 for a pontiac grand prix 2002

turn the key on for 10 minutes or more if you want. then you will see the security light stop blinking, then you turn the key off. you repeat this three times then it should start. Good luck.
somtimes they are quick and easy, and some times you have to do it a couple of times. make sure your battery is charged up.

What causes the security light to start flashing and disable the starter? have to wait with the key on, and it is becoming a real hassle

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!

GM Passlock I & II Information

Please study the following information carefully WHEN INSTALLING REMOTE START systems on a 1996 or later GM car or truck.
Introduced in 1996, GM has changed the VATS anti theft system to Pass-Lock system. This is a similar device to the VATS system, in that there is a resistor present during the start cycle. However, in the PASSLOCK system, the resistor has been placed inside the ignition switch, instead of the key. See the GM V.A.T.S page for more information.
To remotely start a car with this feature, you must bypass the PASSLOCK system. There are two methods of doing so.. The first, is to permanently bypass this system. This is the easiest method for accomplishing your task. The second way, is to temporarily bypass the PASSLOCK, by introducing relays into the system, which retain all of the features of the system, while allowing your remotes start module to bypass it automatically during a remote start cycle.
Vehicles effected
(1996 and newer): N & J body cars, such as
Pontiac Sunfire and GrandAm Passlock-1
Chevrolet Cavalier Passlock-1
Buick Skylark Passlock-1
Oldsmobile Achieva Passlock-1

1997 or newer
Chevrolet Malibu Passlock-II
Oldsmobile Cutlass Passlock-II

1998 or newer
All trucks , SUVs and Vans Passlock-II

It is important to pay special attention to the fact that there are many different ways of achieving the same goal. There are actually 2 different Passlock-II systems. On the next page, there are tests to establish which type of passlock-II your car has.

Relays shown are standard automotive 5 pin spdt relays, available from IEI.
A multi meter is required to measure the resistance values. Accuracy is important within 5%.

Once the value of the resistor is measured, a resistor of the same value +/-5% must be purchased (Radio Shack, for example). You can also use a Potentiometer (POT), which can be adjusted to the same value of the resistor in the ignition switch.

pslc1.gif Passlock-I bypass procedure....

1: Remove the top and bottom shrouds from the steering column.
2: Find the 3 wire ribbon cable, coming from the ignition switch, containing White, Black, Yellow (Sometimes White, Black, Black). These are THIN wires.
3: Locate the Black 6 position connector on the LEFT side of the steering column, right above the ignition switch position. There is a BLACK (Thin) wire in this connector, called "Bulb Test", which shows Ground with ignition in the Off position, OPEN in the "Run" position, and GROUND in the "Crank" position.
4: Turn the ignition switch to the "Run" position. Do not crank the car.
5: Cut the Thin Yellow wire and strip both ends.
6: Without cutting the Black wire, expose some of the copper.
7: Using the ohmmeter, measure from the Yellow wire (the end coming from the ignition switch), to the exposed Black wire and record the value. Measure more than once to assure you have the right value.
8: Acquire the same size resistor and 3 relays, and perform the connections shown in the diagram below.

pslk2.gif PASSLOCK-II bypass procedure

There are 2 types of Passlock-II systems. To determine which system you have, follow these instructions;

1: Locate two wires, which are THIN and are in the main ignition harness.. Orange/Black (or Black) and Yellow.
2: Cut the Yellow wire, and strip back some of the insulation from the Orange/Black (Or Black) wires.
3: Turn the ignition to the "Run" position ( don't crank the starter). Measure and record the value measured from the KEY SIDE of the Yellow wire, to the Black/Orange wire.
4: Turn the key to the "Crank" position and release. Now read the value again.
pslk3.gif5: If the value changed, follow "Method#1". If the value stayed the same, follow "Method#2".

My 2002 Grand am is have a passlock problem. The

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.
