Let it sit for about an hour, untouched to let it clear out of theft mode. If it doesn't start with a programmed key after that, you may have to take it into a shop and have it looked at. It may just be a bad transceiver but if any piece of the system has been replaced the keys have to be programmed with a dealership scan tool.

Changed steering column n won't atrt


Where is the ignition switch at , on the steering column ? Did you transfer the theft deterrent control module from the old column to the new one ? Do you have any lights lit on the dash , SECURITY ? Your car has a anti-theft system , the key has a transponder pellet imbedded in the head of it . Behind the plastic cover of the steering column ,around the ignition lock cylinder is the theft deterrent control module an antenna !
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. The VTD system prevents vehicle operation if a valid (learned) transponder PASS-Key?®III (PK3) ignition key is not used to start the vehicle. The theft deterrent control module has an exciter that is part of the theft deterrent control module as an assembly. The PK3 key has a transponder embedded in the plastic head of the key. The exciter is an antenna which is made up of wire coils which surround the ignition lock cylinder. The PCM enables the engines starter and fuel delivery system when it receives a valid (learned) password from the theft deterrent control module via the class 2 serial data circuit. The components of the VTD system are as follows:

I need to get passed the anti theft reset to get my 2000 cad.devlle.going, just bought it, I need help to locate fuse boxes, would like to trade somebody for a sharp running truck or car straight across,...


One is under the hood in the engine compartment an Rear Fuse Block
Left rear of the passenger compartment, under the rear seat ! There are a couple of fuse's , but they power up the ignition an the PCM ,so you can't pull those ! Beside that if the PCM does not get a fuel enable signal from the anti-theft module the vehicle won't start . You can't just disable thing's on this vehicle ! If you have security light on steady or flashing you need to take it to someone who has a diagnostic scan tool that can check DTC'S - diagnostic trouble codes ! A code reader can not access these type codes !
Vehicle Theft Deterrent (VTD)Circuit Description
(VTD) Theft Deterrent System Components
Ignition Key (Transponder) The ignition key for the (VTD) theft deterrent system is a typical ignition key with a transponder pellet located in the plastic end of the key. The ignition key transponder value is used to determine if a valid ignition key is being used to start the vehicle, there are approximately three trillion different transponder values available. This vehicle has two types of ignition keys.
?€¢
Master key (black plastic end) which can start the vehicle and lock/unlock all door locks, all storage compartments and the rear compartment lid lock.


?€¢
Valet key (gray plastic end) which can start the vehicle and unlock/lock all doors, but can not unlock/lock the storage compartments, or rear compartment lid lock.

Important: The transponder values are not readable and can not be serviced separately.
Theft Deterrent Module The theft deterrent module contains the software for controlling the VTD System. The theft deterrent module uses the following inputs and outputs to control the VTD system.
Inputs ?€¢
Battery voltage from the underhood fuse block PCM/BATT fuse, circuit 240 (ORN).


?€¢
Ignition start voltage from the ignition switch, circuit 1390 (WHT).


?€¢
Ground, circuit 450 (BLK).
Outputs Password exchange with the PCM (fuel enable), class 2 message circuit 1807 (PPL).
Powertrain Control Module (PCM) The PCM verifies that the passwords received from the theft deterrent module via the class 2 serial data line are valid. If a password is invalid the PCM disables the fuel delivery system. If the password is valid the PCM enables the fuel delivery system.
Starter Relay The starter relay is controlled by the PCM module via class 2 serial data (CKT 1807 PPL). If the theft deterrent module measures the correct transponder value, the PCM module switches the starter enable control (CKT 447 YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.

How to reser Theft Deterrent Module on cobalt


The antitheft 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.

1998 oldsmobile intrigue and security light keeps coming on flashing and the car won't start. but now its not flashing and the car still wont start what do i do or what could be wrong?


The problem is in the key or ignition. Aside from the key working like a normal key, it also has a chip or transponder in it that is part of the security antitheft system. The key is then read by the ignition and must communicate the correct signal. If there are any break in communication, the system goes into anti theft and locks out the starter. Might be a key issue or an ignition issue. The fact that the light is flashing, indicates key or ignition. If it were solid, then the problem would be the Theft Deterrent Module (TDM) that is the main computer of the security system. You can either fix the problem part, take it to a dealer who is authorized to fix it, or bypass it entirely. This link explains the system and how you can fix it yourself. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Code P1632


These cars had a tendency to "lose" the password for the theft deterrent system. Your body control module doesnt understand your key, therefore tells your pcm to discountinue fuel supply. To reprogram the system, start the engine and let it stall. Leave the key in the run position. The theft light should flash for 10 minutes. When the light stops flashing, Turn the ignition off for 10 seconds. Turn the ignition back to the run position. This procedure tells the BCM that on the next ignition cycle, to accept the new password. Now, it should start. If not, it may require the clearing of the code, and possibly the reprogramming of the PCM, which needs to be done with a dealer scan tool or equivilant.
