To deactivate the anti-theft lock system in a 2007 Cadillac STS, insert the key into the ignition and turn it to the "On" position without starting the engine. Wait for about 10 minutes until the security light turns off, then turn the key to the "Off" position and back to "On." This process resets the system. If you're having persistent issues, consult your owner's manual or a professional mechanic for assistance.
