The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

SOURCE: HOW DO YOU FIX THE

I am assuming the light you are talking about is the "SECURITY" light on the dash. Your Alero is equipped with GM's Passlock system which cuts fuel to your engine if it determines that a source other than the key is trying to start the car.

I found this online, i posted it somewhere else as well and heard it would work...goodluck

PASSLOCK I or II DISABLEMENT
The following is a procedure to disable Passlock I or II Systems for vehicles in which remote start/stop system installations are required. This procedure is required because a remote start system will not function with the current Theft Deterrent System (Passlock) which is included on many 1996 and up GM vehicles.

Please note that this modification is intended to be used only in conjunction with the installation of a remote start/stop system and does not provide a procedure to install a remote start/stop system.

CAUSE
If an attempt is made to start a vehicle by a means other than a key rotation in the ignition switch, the Body Control Module (BCM) will interpret this start as a vehicle theft and disable the fuel injectors.

CORRECTION
A minor wiring modification may be made to allow the vehicle to be started remotely. This modification includes adding a switch to allow the customer to select "ON" to disable Passlock or "OFF" for normal Passlock operation.

CAUTION: When this modification is performed and the switch is set to the ON position, the theft deterrent feature will be disabled. When the theft deterrent is disabled the SECURITY or THEFT telltale will light up indicating that the theft deterrent system is NOT functioning.

PASSLOCK MODIFICATION
Refer to appropriate GM service manuals and/or SVMQP Electrical Guideline Manual for instruction on splicing and electrical connections.
1. Select a suitable on-off switch (see note below) which will be used to disable/enable the Passlock System. Mount the switch in a location such that it is accessible to the driver and will not interfere with normal vehicle operation.
NOTE: This is an extremely low current circuit (approx. 7mA), it is therefore very important that a high quality, low energy, fast acting switch be utilized for this application.
2. Turn the ignition switch to the OFF position.
3. Locate the Main Ignition Switch Harness in the Column. GM's Passlock System wires exit the Ignition Switch Tumbler together and then join with the Main Ignition Switch Harness. (See http://www.bulldogsecurity.com/ or http://64.85.6.118/diagrams/diagrams.asp and select your Make, Model and Year for wire colors and clues on the quickest way to access these wires.)
4. Locate the Yellow Passlock Data Wire which is included in a bundle of three tiny (20 GA) wires wrapped in friction tape.
Cut this wire and splice a 0.5mm2 (20 GA) yellow wire to each end of the cut wire.
Keep wire length to a minimum. Route modification wires clear of moving parts.
Connect the yellow wires to the switch such that the contacts are OPEN when the switch is in the ON position.
5. Turn modification switch to the OFF postion (contacts closed).
6. Start vehicle to verify normal operation. If engine "cranks but will not start" recheck the switch position (contacts should be closed), wire connectors and modification wiring.

SWITCH OPERATION
To enable remote start:
Start the engine with the ignition key (modification switch must be in the OFF position). Turn modification switch to the ON position (contacts open). The SECURITY or THEFT telltale will light up indicating that the Passlock System is inoperative.Once the SECURITY or THEFT telltale has been on for at least 5 seconds the vehicle can be turned off and then remotely started.

To disable remote start:
The Passlock System can be reactivated by turning the modification switch OFF (contacts closed). Vehicle can either be running or off when this is done.

Please note that the VCM/PCM will record Diagnostic Trouble Codes (DTCs) related to the security system when the modification switch is in the ON position (circuit open). This is due to the way that the VCM/PCM interprets this condition.

NOTICE
Any condition which removes battery power from the Vehicle Control Module/Powertrain Control Module (VCM/PCM) (e.g. dead battery, disconnected harness connectors, etc.) will prevent the vehicle from being restarted. If the engine exhibits a "cranks but will not start" symptom, place the modification switch in the OFF (contacts closed) position. This will reactivate the Passlock System and allow the vehicle to be started with the ignition key.

Hope helps (remember to rate and comment this).

Hi,

Just need some additonal information:

Am wondering - how did you diagnose the ignition switch as being the initial problem?

Were any fault codes read from your vehicle's computer?

Does your remote fob (keyless entry) operate the central locking system without any issues?

Await your response...

02 olds alero no start system shut down


Where did you try to by-pass at , with the 2000 ohm resistor ? Is the SECURITY light lit on the instrument cluster ? Probably has another problem other then the key . The anti-theft system in your vehicle can not be by-passed by using a resistor .

The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.

Your best bet , take it to a qualified repair shop . Before you render it unfixable . (cost to much )

Water leaked through my front window and the fuse box got wet now my car turns over starts then dies,what should i do i have a 1999 alero


Might have to do with the anti theft security system that GM installs. When it "dies", look on the dash for a light that says SECURITY, if you see this, then the anti theft is shutting you down and you need to read this link for answers. http://vatspasslockpasskeysecurityhelp.yolasite.com/

I HAVE A 2000 ALERO THAT THE ABS LIGHT WON'T GO OFF CAN YOU TELL ME HOW TO RESET IT


You have to fix the problem with the ABS first. If you have done this, you can reset the light by leaving the battery cable (negative cable) unhooked for 15 minutes. If you have a factory radio with OEM anti-theft, be sure you know the code before you unhook the battery.
