What is the security code?


Your SECURITY light lit on the instrument cluster ? or you disconnected the battery an now the radio is locked ?
The theft deterrent system on this vehicle is comprised of the vehicle theft deterrent (VTD) system. VTD prevents drive away theft by preventing the vehicle from starting.
SECURITY Indicator The SECURITY indicator on the instrument cluster is controlled by the VTD system. The SECURITY indicator is located inside the instrument cluster. The SECURITY indicator is controlled by the body control module through the class 2 data line. The VTD system contained in the BCM commands the instrument cluster to control the SECURITY indicator only when the ignition switch is ON. The VTD system uses the indicator as a malfunction indicator.
Theft Deterrent
The "Theftlock" theft deterrent system is a feature on all base and uplevel radios. There is no need to program a security code into the radio as in past model years. The theft deterrent system now utilizes class 2 serial data to determine if the radio is in the appropriate vehicle. Each time the radio receives the "run" power mode message, it compares the VIN information it has stored to the VIN information received from a module on the class 2 serial data circuit responsible for transmitting that information. If a mis-match occurs, the radio display will indicate to the user the radio is locked. Once this takes place, a DTC will set, the radio will not respond to any button presses and become inoperative. The two scenarios able to cause this condition are:
?€¢
A radio is installed from another vehicle.


?€¢
A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle.

The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.
So what problem are you having ?

How do you bridge-out the anti-theft security system....it keeps kicking in and shutting down the van after starting


There is a problem detected within the security system by the security module. Try locking and unlocking the door with the key fob to reset the system. Sometimes locking and unlocking the drivers door using the key will reset the system as well. If still no luck, try the spare key to see if the security system accepts it

Why my key will not unlock my door manually on my 2007 ford edge.why the anti theft mode is on the dash.


The manual unlock is operated by a set of small levers in the door. Either the connecting rod between the key mech and the door lock has become loose or the mechanism inside the lock itself is faulty.
Modern cars don't like being unlocked manually, you might have tripped the security system by trying to unlock the door, which could be why the anti-theft mode is giving you a warning. It's usually more of a warning that someone has tampered with the door locks and couldn't gain entry or something like that. If your car came with a manual for the security system, read up on it.

This is from Ken on CarPros:
Here is the way to reset the security system.

https://www.2carpros.com/articles/how-to-reset-a-security-system

Here is the systems descriptions

There are 2 security system, namely anti-theft and immobilizer.

Here are the 2 systems.

DESCRIPTION & OPERATION
Anti-theft system is controlled by Body Control Module (BCM). BCM receives signals from hood switch, trunk switch, door switches and Local Control Modules (LCMs). There are 5 LCMs located throughout vehicle.

To set anti-theft system in armed mode, remove ignition key, close all doors, trunk and hood. Lock doors using key or remote controller. The SECURITY light will illuminate for 30 seconds, then flash in 2.4 second intervals, indicating system is in armed mode.

To cancel armed mode, unlock and open any door or trunk lid using key or remote controller. SECURITY light will flash every second, indicating system is disarmed.

Alarm will activate (horn sounds, headlights flash and starter circuit is disabled) if any of the following conditions occur while system is in armed mode:

Engine hood or trunk lid is opened using the hood or trunk lid release.
Door(s) is unlocked without key or remote controller.
Tampering with any door/trunk lid key cylinders.
To deactivate anti-theft system, unlock door or trunk using key or remote controller.

If it is the immobilizer that is preventing the engine from being started, ensure you have the correct key and the transponder is intact. Quite often keys are dropped and if it breaks open, the internals would scatter all over. When this occurs, there is a tendency for the transponder to be lost.

Please let us know happens so it will help others.

Best, Ken
I hope that helps you out!

If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key's key-less entry signal, or there may be a fault in the anti-theft module or wiring.
There is a reset procedure to stop this anti-theft light flashing.many a times this helps The reset procedure is as follows:-- Reset the alarm by locking and unlocking the drivers side door.Do this a couple of times and then check it will reset the factory security system .

1992 chevy corvettecranks but doe's not start.fuel pump not working but good.fuse good doe's not have power to fuse at all.


The built in factory anti-theft system disables the fuel pump if it is triggered, or this can be caused by a fault in the anti-theft, those are a few of the reasons, arm and dis-arm anti-theft is it working properly? Follow this procedure to check security system:

The Security System is reset by unlocking the driver's door twice with the Ignition Key, but if it does not reset, most likely the Ignition Lock Cylinder has failed. It has small contacts which 'sense' the pellet on the key and transmits that data to the Anti-theft Module. Often the contacts, or the micro wires, break causing the module to think you have no key in there. The ASR may be illuminating since the Security System is active, trouble codes?
