Its the battery. The colder it gets the less cranking amps it has. Keep the car in garage or get a battery wrap warmer. Also try to get a battery with the most cranking amps for the size battery it will take.

My 2003 cts won't start when it's cold outside. I've checked the battery SnF the alternator and I also had a new fuel filter and pump put in. Sometimes when it doesn't start it'll say service theft system...

Have your dealer or a qualified Cadillac mechanic check the anti-theft system and your key. Your ECM may need to be re-flashed, but have a diagnostic scan performed to determine possible solutions.

Are your power seats working? Mine shorted out and several days later my battery was dead because the short was drawing power from the battery when the car was not running. If your battery and charging system check out o.k, I would say you have some kind of parasitic drain on your battery.
