The battery died on my 2005 Cadillac STS this morning. I jumped the car but no luck. I get "security indicator" icon on the dash board. It means that "starting is disabled by a security feature". I've been told I will have to replace the battery and have a dealer reset the anti theft system. Is there a way to reset the anti-theft system without having to take it to a dealer? If so, how do I do it?
I replaced the battery but no luck. Please don't waste money in replacing the battery. Follow the below instructions. It worked for me. I tried this procedure after towing to a local mechanic as he could not find any reason why it is not starting.
1. Put key into the ignition and turn it to the ON (RUN) position. A "Security" indicator light on the
dashboard will stay on for 10 minutes & 10 Seconds.
2. Within 1 minute after the indicator light goes off, turn the ignition to "OFF" then return to the ON
(RUN) position. The indicator light again will stay on for 10 minutes & 10 Seconds. (DO NOT REMOVE THE
3. Again, within 1 minute after the indicator light goes off, turn the ignition to "OFF", then return to
the ON (RUN) position. The indicator light again will stay on for 10 minutes & 10 Seconds. (DO NOT
REMOVE THE KEY)
4. When the light goes off for the third time, the new key is programmed into the computer. Remove the
key and then re-insert it into the ignition lock and start the car.
All previously stored codes will be erased. To stop the process at any time, simply remove the key and
use an existing key to start the car.
Note: I tried and after first 10 minutes & 10 seconds, ""Security" indicator light on the dashboard" did
not go off, I removed the Negative terminal of the battery, waited for 15 minutes and then re-connected it
back to battery. Now again i turned the key to "ON" position and within 5 seconds, security indicator
light went away. I turned the key to Off position again and redo the same thing for two more times
before i started the car. It started withing any message on Dash board.

Before you spend money on a new battery or new computer, try getting a new key made. I had this problem and was bypassing by using a wire to jump ignition wire to + battery terminal. A friend suggested my key may be worn so got a new one. All fixed!
