How to Reset the Passlock System on GM Cars
Image of a man driving a car taken by palm trees from Fotolia.com A broad range of General Motors vehicles are equipped with a passlock theft system, which is designed to prevent GM vehicles from being stolen. GM automobile owners, on the other hand, are not unusual in experiencing problems with their passlock system while attempting to start their vehicle.
During this time, you will notice that the security (Theft Sys) light is flashing at random intervals and that you will not be able to start your car. In order to deal with this annoying malfunction, you can restart your car’s passlock system when it starts up.
Step 1
To begin, insert your key into the starter and start your automobile as you normally would, then allow it to stall. Hold down the “On” key until you are finished. To put it another way, do not return the key to the “Off” position. When the key is in the “On” position, you will be able to use the air conditioning, listen to the radio, and see all of the lights on the dashboard, which will indicate that the key is in the “On” position.
Step 2
Wait until the “Theft Sys” light on your dashboard does not flicker and remains illuminated. It will take roughly 10 to 15 minutes to complete this task. Once the “Theft Sys” light has been illuminated for a sustained period of time, the vehicle should be started immediately. Keep in mind not to switch off the ignition. Your vehicle will now restart and the passlock system will be reset as before. ReferencesTips
- If your passlock system continues to malfunction, it is possible that it is damaged and that you will need to take it to the dealership. A mechanic can also disable the passlock mechanism in order to avoid getting stuck on future occasions
- However, this is not recommended.

Then there are secondary issues, like a fuse or wire in the dash, and so on.
I’ll make an update!
I’m impressed with how well it runs with very little maintenance.
To get the automobile to start, I had to wait anywhere from 20 to 40 minutes at first.
Holding the key in that position for more than a second or two is not something most of us are accustomed to doing.
It simply “disappeared.” When the Passlock security system on a Chevy Silverado is active, the vehicle’s gasoline injectors are turned down, and the car is unable to start as a result.
If the system continually disables the car, or if the simple remedy does not resolve the problem, a separate bypass system may be placed in the vehicle to prevent the security system from activating in the future.
Allow the car to sit for 10 minutes with the key still in the “On” position, then start it.
Make an attempt to start the car.
If it does not, you will need to either take the car to a dealership or install a bypass module to completely bypass the security system on the vehicle.
Bypass modules are frequently employed in the installation of remote starters in automobiles.
There are two different Passlock 2 systems that are in operation.
The potentiometer should be connected to the car, which should be in drive or reverse.
Start the engine by cranking the starter.
Once you’ve established which approach is necessary, follow the instructions in the bypass module kit to finish the installation process.
Make certain that all of the resistors are the same size.

Thank you very much.
When the key is turned to the “Start” position, a resistor located within the ignition switch is detected by the security system, which activates the alarm.
You will need to use a digital meter to test this resistance, and you will need to overcome Passlock when the remote start is turned on.
However, be certain that you use your meter to measure the resistance of the bypass unit.
You will need to cut the yellow PassLock wire that is attached to the door.
It was necessary to remove the steering shaft trim, dash faceplate, and gauge cluster in order to run all of these “boxes” up into the dashboard near the defroster vent, so I did.
I would like to bypass the passlock to the ECM on a 2002 Chevy Silverado? How would I do it?
I wrapped all of the wire and ran it through the steel channels that serve as reinforcement for the dash. In addition, due to the high quantity of current that flows through these connections, I decided to solder all of the connections. All total, it took me the better part of a day to do this task successfully. I’m confident that it will be just as fun this winter as it was last year.

How to Deactivate a Passlock on a 2002 Chevy Silverado
Its purpose is to assist in the education and guidance of technicians in the diagnosis and troubleshooting of security light, “no start,” and engine immobilizer problems on General Motors cars equipped with Vats, Passlock, or Passkey anti-theft systems. These symbols are solely for use with the anti-theft system. This means that they are not related to anything else. I’ve put up this website in order to assist others who are experiencing the same situation. The more recent ones operate on the basis of frequency and transponders.
- Any interruption in this connection during startup, even for a fraction of a second, might prevent your car from starting.
- The idea is that if the key, the ignition, and the TDM do not match and communicate, the security system will fail and shut you off.
- Symptoms of a malfunctioning security system.
- This just became worse and more frequent as time went on.
OK, Now What?
She couldn’t comprehend what was being said. I thought there had to be a more cost-effective solution. It is the TDM in and of itself. These wires are responsible for determining the OHMS of the chip in your key. If you had the ability to circumvent the system by merely cutting one cable, you would. If the Theft Deterrent Module is not functioning properly, this will not operate. Additionally, if you are using a Passlock or Passkey 3 system, this will not function.
I’ve now put three of these in my own personal transportation. I recently completed my Olds Toronado Trofeo, and have uploaded a short video demonstrating how the security system was circumvented, as well as some installation photos to the gallery.

Passlock 2 Passlock ii Passlock II Relearn Reset Procedure
Pass Lock II was installed in a large number of General Motors cars from 1995 to 2005. It may be distinguished by the presence of a security light on the dashboard and an ignition key with the letters PK2 imprinted on the metal portion of the key where it joins the plastic end. There are certain keys that do not have the PK2 stamp on them, but are nonetheless utilized in this system since they have the same function. Only the lock cylinder, which has a magnet in the middle, may be turned by using these keys, which are not used for anything else (Figure 1).
- When the lock cylinder is rotated in the key mode, the magnet will travel far enough to allow the sensor to send a signal to the security module.
- The third wire is a 5V reference signal line from the security module that is pulled to a certain level when the magnet passes through the sensing device.
- When the battery runs out of power or a new hall sensor is installed, you will need to re-learn the Pass Lock sensor value into the security module to ensure that it works properly.
- Now release the key to allow the computer to return to the run position.
- Some cars may begin to crank but then stall, while others may not crank at all.
- After 10 minutes, you will see that the security light has gone off, or that it has just stopped flashing and then gone out.
- After 5 seconds, you should turn the lock cylinder back to the crank position to restart the operation.
- Upon your fourth effort, the car should begin to operate and remain operational.

CAUTION: If you decide to make this alteration, be sure you read this whole article completely and follow the instructions to the letter. Do not skip any of the steps in the process. I’ll say it again. Make sure you don’t miss any steps.
The Problem
You attempt to start your General Motors automobile. The engine begins to run, but dies after one or two seconds, and the “SECURITY”light begins to blink intermittently. OR. You’re driving along when, for no apparent reason, the “SECURITY”light illuminates completely and remains illuminated. After you have shut down your vehicle, the SECURITY light will remain illuminated until you restart your vehicle. This is a prevalent problem on the following General Motors automobiles: Oldsmobile Alero from 1999 to 2004 Chevrolet Malibu from 1997 to 2003 Pontiac Grand Am from 1999 to 2004 The Security Module, which is a component of the Ignition Lock Module, is frequently the source of the problem.
“If the SECURITY light flashes or remains illuminated after attempting to start the engine, wait ten minutes with the key in the ON position until the light goes off.
Unfortunately, you will most likely have to go through the same process all over again a few of weeks later.
The instructions in the menu to the left will walk you through the process of bypassing the Passlock Security System on a 2003 Oldsmobile Alero and permanently turning off the “SECURITY” light.
There are only slight variances in the methods used to remove the radio from the vehicle in order to access the wiring.
They are color coded as follows: black (analog return), white (power), and yellow (analog data).
By removing the radio from the dashboard and reaching through a hole in the radio compartment toward the steering wheel, the three wires may be reached and accessible.
Tools and supplies are the next step.
