The theft or lock 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.

you can reset the system by turning key to on position for 5-10 mins and then try starting it but its probably a short or grounding prob try the engine to chassis ground

SOURCE: 88 cadillac deville, ac blower fan wont shut off,

Ralph,
Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.
Charlie
PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.

SOURCE: starting disabled due to anti-theft system

Almost always the key is not at fault. I know for sure heat changes the resistance of the key but it does not happen as a usual thing you would have to apply physical heat. Contact me at albmahone@yahoo.com

SOURCE: 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 cadillac 04 cts wont start. Thinks its the scurtiy feature. Any1 have a idea


Is the security light lit ? Car an pad lock symbol . If any of these are lit it is the anti-theft system . Does the engine crank over but won't start an run ? The anti-theft system will allow the engine to crank but not start , disables fuel injectors . If the anti-theft light is lit there are DTC'S diagnostic trouble codes stored in the theft deterrent module an or the ECM .
Does anything happen when you turn the key to the start position ?

I have a 2001 Cadillac deville that will not start when I turn the key it clicks for a few seconds and nothing. The service anti thift soon came on, on the dash the day before the radio stopped working...


It's hard to say for sure since it sounds like it could be many things. If you turn the key and you hear a few clicks coming from the engine and then nothing, it could mean a very very weak battery. Your first step should be trying a different (fully charged) battery. Good luck.

Dealer gave me a shaved key works on starting ignition not on door lock the other three keys work on everything car doesn't have engine immoboliser removed the remote keyless entry fobs what is


Many times the dealer gives you a valet key made to give to the vet to park your car, these keys work even though the theft deterant system is active, but they will only work for short periods untill the theft system activates and imobolizes the vehicle. The system is reset when the valet brings your vehicle and you insert your normal (chiped) key.

Theft service system wont let vehicle start


Generally speaking, if the security light is on and the engine will not crank, the VATS system is not reading the chip in the key.
Either the chip has failed, or the sensor in the lock cylinder, or the VATS module.
You could try a spare key but most times you have to have a shop make the repairs.

2005 grand prix wont start,saying service theft system.


The problem is either gonna be in the key itself or the theft deterent module which is what the key cylinder is in thats what reads the key. Yes you can do all of that reset if you want but eventually it not gonna work and who wants to do that all the time. Remember its either the key or the theft deterent module J byrd Automotive

When I get inside and try to start the car it won't start and the theft light on the dashbord just keeps blinking.


I don't know what type vehicle you have but it sounds like you theft deterent module is activated. Look in your owners manual and it should tell you the procedures for deactivating the theft deterent module. Last one I deactavated was a 2001 GMC, key "ON" key "OFF" key "ON" key "OFF" key "ON" and let sit for 20 minutes, then try to start the engine. Good luck, Gary

My 98' deville wont start whenever i put the key in the ignition all the gauges lite up but engine wont start. The l.e.d display tells me "starting disablledremove key...i have no idea what to do..


The resistor chip in the key may be damaged or the sensor in the ignition may be damaged. You can have the ignition replaced or disable the theft deterent by hard wiring in the proper resistors. Search the cadillac forums for details on how to do this.
