It is not recommened to bypass this system, you might open a can of worms, most likely the key sensor in the ignition lock cylinder is defective, this is the most common issue, the other is the door switches.

Where is trsnreceiver in 99 cadillac sts


Anti-theft system transceiver ?
Theft Deterrent System
The Theft Deterrent System on this vehicle is comprised of two separate systems, the Personal Automotive Security System (PASS-Key?® III) and the Content Theft Deterrent (CTD) system. These system are described and diagnosed separately within this section. For CTD operation, refer to Content Theft Deterrent (CTD) Description .
SECURITY Indicator The yellow indicator SECURITY on the instrument cluster is controlled by both the PASS-Key?® III system (VTD module) and the CTD system (RIM).
?€¢
PASS-Key?® III system, the VTD commands the instrument cluster to control the indicator only when the ignition switch is ON.


?€¢
CTD system, the RIM commands the instrument cluster to control the indicator only when the ignition switch is OFF.
PASS-Key?® III System The PASS-Key?® III system is designed to help prevent vehicle theft by disabling the engine unless an ignition key with a specific electrical value is used in the ignition lock cylinder. The PASS-Key?® III system operates independently of the CTD system. Protection is provided even if the CTD system is not armed. The components of the system are the ignition keys (black or gray), ignition lock cylinder, Theft Deterrent (VTD) module, Reader Exciter, Powertrain Control Module (PCM) and two starter relays (START 1 and 2) in the underhood fuse block.

My 1990 cadillac seville says (starting disabled,anti-Theft system. wait 3 minutes then start.) But still does not start.


This happens when there is a break in communication between the chip in the key, the ignition, and the TDM (theft deterrent module). When these parts are not communicating properly, the antitheft system locks out the starter. Without the correct signal being sent completely through the system, the car considers it to be an illigitamate key and shuts down the starter to prevent HOTWIRING and eventually theft of your vehicle. Its a good system when it works properly. The problem can be as simple as a worn out key or as serious as a bad TDM which can run up to $1000. There are ways around this system for a cheaper cost, this link will help you troubleshoot the problem and educate you on the system. There are also some links to help you fix this yourself. This is a very common GM problem, so you are not alone in this.

You may have a failed ignition lock cylinder The wires that are attached to the lock cylinder are probably broke therefore the resistor value of the key pelet is not getting to the theft system module there fore without tha signal the car will not start. to repair the car will need a new lock cylinder and at least one new key

Cadillac seville won't start due to theft system


If you know how to solder, you can try building up the "chip" area on the key and reinserting it. That's the only thing that controls the PASSLOCK theft system.

Measure the resistance from one of the contacts to the other with an ohmmeter, and you can get those keys from eBay. Once you get the car home, order one for a couple bucks, and get it cut at your local hardware store.

When you order the new key, they will ask you for the resistance measurement across the resistor embedded in the key, and send you one that matches.

If you'd rather order one from the dealer, they are still available last I checked, but were significantly more expensive than the eBay option.

Cadillac seville won't start


I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

My 1991 cadillac seville will not start


Get a new cylinder put old key with chip in it. Find orange wire from old lock cylinder at bottom of steering column just under dash. Disconnect and connect new wire from new lock cyl. Get a copy of the old key for the old lock cylinder {no chip needed} to start car. Hide or mount new lock cylinder hidden under dash. Remove chip key to activate theft system.

How can I bypass a anti auto theft system on my 1990 cadillac seville?


I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer
