I would suggest you have someone check the hood sensor. There is a sensor that tells the computer the hood is open much like when a door is not closed.
Anytime a sensor like that fails, the computer will think someone has cut the wires or otherwise disabled the sensor.

SOURCE: how do you release emergency brake on 2002 cadillac sts .

Try pushing down on the e brake further nad releasing it. Usually that's how to release them. Good luck, if that doen't back the car up and put full application to your service brake then try pushing down on your E brake again to relise them. Good luck and hope this helps

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: 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.

Service security system and hood open keep going off


You will need to have the Cady dealer scan the systems control module for faults to be sure what is causing this. You can also try replacing the hood open sensor or seeing if it bent and not sensing the hood is fully down/latched.

2005 sts wont start. Says no FOBS detected. Please help?


Are both FOBs doing this? If it's only one I would replace the FOB battery.
NO FOBS DETECTED Message on DIC, No Crank/Start Unless Fob in Center Console Pocket or Remote Keyless Entry (RKE) Button Inoperative (Replace Remote Control Door Lock, Theft Deterrent Receiver Assm) #04-08-52-008

Tell the Dealership to look at this. They should be able to fix it quickly.

Keep us updated.

My 2006 cadillac sts key fob all of a sudden is not working it says no fob detected and i have the fob what can b wrong??


Some late model fobs contain electronics beyond the push buttons.
Batteries are replaceable...small screws may let you do this.
If the battery is not the cause....a replacement fob may be expensive. A road service technician can probably troubleshoot and replace cheaper than dealer !

After my husband changed the battery in my STS, the CD player will not work. I have 3 CD's loaded in the player. It will not play or eject.


You need enter the unlock CODE for extract your CDs; check in your owners manual (any label in the last page .

THEFTLOCK is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle.

With THEFTLOCK® activated, the radio will not operate if stolen.

Fot other details can check 2005-Cadillac-STS-Owners-Manual

Hope helps.
