Does the theft light on the dash stop the truck from starting?


Depending on the vehicle the theft light may stop your truck from starting, if the key has a chip in it for security it may be the problem or your ignition switch possibly

Car dies when I use my remote start and press the lock or unlock button


This is most likely caused by the car's anti-theft system. Most newer cards require a separate module to be installed to override the anti-theft system while the remote start is in use. Otherwise, when the anti-theft system detects an anomaly, it will immobilize the vehicle.
DEI makes a 556H module for this purpose. The link shows the instrall manual for this device.

HOW DO YOU FIX THE ALERO ANTI THEFT PROBLEM IF IT KEEPS COMIING ON


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).

When anti theft light is blinking the car wont start. Can you bypass the anti theft device


On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.

No start cranks but does not fire has spark. has fuel if bypassed by relay fuses good new fuel pump a year ago has fuel replaced battery froze, has prostart remote start, been in 8 years no issues 2000...


check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.

I start my car but it immediatly shuts off and the theft sys light flashes could this light be the reason?


the ignition swith reads the key chip when key is turned, this is a common problem,the ignition switch will need to be replaced, after replacing the swith reprograming will be needed, to program you will need a battery charger to keep battery from going dead, after installing new switch,turn charger on, turn key to crank then release key leaving ignition on, you will see the dash lights, leave key on for about 15-20 min, until you see theft light go out, if light doesnt go out then repeat process,crank for 2 sec, then leave key on 15-20 mins until security/theft light goes out, hope this helps.

Would anti theft cause car to quit


Sounds like a bad ignition switch have ur body control module checked for codes if u have a B2960 and or B3033 then replace the ignition switch.

SECURITY
If your vehicle has the remote keyless entry system, this feature allows you to select the method used to arm the vehicle's security system. When SECURITY appears on the display, press the reset button to scroll through the available settings:
* RKE (Remote Keyless Entry) (default): The content theft-deterrent system will arm when the lock button on the remote keyless entry transmitter is pressed or when the power door lock switch is pressed.

* PASSIVE: The content theft-deterrent system will arm itself 60 seconds after the ignition has been turned off and all of the doors have been closed.

No power to anything - how do I reset anti-theft system? Checked battery at Wal-mart - print out says okay low on charge. Charged battery for several hours on slow charge and then fast charge. Battery...


no... no power to anything means like the headlights are inop and such

in that case its a battery or battery cable issue

assuming you have headlights and power to accessories and the vehicle still will not start AND the theft light is flashing then YES your anti-theft system is trying to keep the car from what it thinks is a theft issue

simply pressing the unlock button on your remotes will resolve this

assuming you do not have the remotes then you will need the anti-theft computers reprogrammed at a dealer or good garage

keep us posted
