Usually the flashing security light means the computer is not finding the right code in the key chip.
Is the key you are using programmed to the vehicle ?

SOURCE: replaced ignition and steering wheel now car wont start -security light on

Hi......
On your Buick 94.
The problem is the ANTI THEFT SYSTEM..
If you have replaced the ignition switch.
If you are using a NEW KEY, the car won't start.
Because in the OLD KEY, is there a Resistence with a number of ohm's
The computer need the resistence to activate the the signals to operate the vehicle.
OK.. with the New Key and Old Key you can go to any Aloha Smith and they will remove the Chip from the Old Key to the New Key.
And the car must start and running.

But if you are using the Same Key that you have before the repair made.
I recomend to check the 2 Orange wires from the Ignition lock Cylinder to the steering column lower connectors.

Ok I hope this work for your problem.
Any moree info, I will glad to help you.
I'm a Mechanic and have all the repair information for all the cars.

Thank you for use fixya...

Pass key is the security system which disables the car if it is stolen. You need the remote or a key with a chip to start the car. go to a dealer, prove ownership with registration and they will be able to help you out

Hello Narisol,


Excerpt from the 2003 Owners Manual.


Passlock

Your vehicle is equipped with the Passlock theft-deterrent
system. Passlock is a passive theft-deterrent system.
Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder
is tampered with, the fuel system is disabled and the vehicle
will not start. During normal operation, he SECURITY light
will turn off approximately five seconds after the key is turned to
RUN. If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before trying
to restart the engine. Remember to release the key from START as
soon as the engine starts. If the engine does not start after
three tries, the vehicle needs service. If the engine is running and the
SECURITY light comes on, you will be able to restart the engine
if you turn the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to
check the fuse. See Fuses and Circuit Breakers on page 5-85.
See your dealer for service. In an emergency, call the M
Roadside Assistance Center. See Roadside Assistance Program on
page 7-5.


Excerpt from the 2003 Owners Manual.

Testing the Alarm The alarm can be tested by following these steps:
1.
From inside the vehicle, Iower the driver's window and open
the driver's door.
2.
Activate the system by locking the doors with the power door
lock switch while the door is open, or with the remote keyless entry transmitter.
3.
Get out of the vehicle, close the door and wait for the SECURITY light to go out.
4.
Then reach in through the window, unlock the door with the manual
door lock and open the door. This should set off the alarm. When
the alarm is set the power door unlock switch is not operational.
If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the headlamps do not flash, the
vehicle should be serviced by your dealer.

Car wont start even after jumping it. No lights, etc. except for the security light. What's wrong?


Hi Linda , your vehicle has a anti-theft system problem ! Jumping it is not going to help ! The anti-theft system stops the starter from working ! Do you headlamps shine bright ? Horns work normally ? If you look at that security light when trying to start the vehicle does it flash rapidly ? Your going to need to have taken to the dealer , there the only one's that have the diagnostic tools to find out what is wrong !

My 2001 Saturn wont turn over, no click or anything. I do have good battery power.


Security system failure is a common problem on GM vehicles. Every time you put your key in the ignition, the vehicle's security system reads the signal from your key to make sure it is OK to run. When it receives the "correct key" signal, the security system allows the starter to turn over, and/or the fuel injectors to function and your car works like it normally does every day. If you were to use a different key, or try to hot wire it, the system would shut down these parts of your car, thus making the vehicle completely immobile. This is GM's way of preventing vehicle theft. The problem is that the system is known to fail quite commonly. It has been failing consistently for around 30 years. When it fails, two things can happen. First, you turn the key and nothing happens at all. Lights work, radio works, windows work... just not the starter that you need to start the vehicle. This is a "starter immobilizer". Second, you turn the key and the vehicles starts just fine, but then stalls in 2-5 seconds. This is a "fuel immobilizer". It literally cuts off the fuel injectors and stalls the vehicle to immobilize it. These are normally, but not always followed by a light on the dash that says SECURITY or ANTITHEFT. These lights are to inform you of the system's failure to collect the information it needs from your key to the computer. If your security/antitheft light is on, odds are you will be stranded soon, if not already. Remember that the security system controls the security light. If the system is failing, the light may never warn you of the failure. http://vatspasslockpasskeysecurityhelp.yolasite.com/

My 2006 jeep commander will not start.


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

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.
