How to Deactivate Cadillac Anti-Theft System?
2 Answers
Turn the ignition switch to the "ON" position, wait for 10 minutes until the anti-theft indicator light automatically turns off, then the anti-theft status will be deactivated. Turn the ignition switch to the "ON" position, wait for 3 minutes, then turn off the ignition switch. After that, start the engine and let it run for more than 30 seconds to reset the throttle position.
Last time my Cadillac's anti-theft system locked up, and I couldn't open the car—it was so frustrating. This often happens due to a dead key fob battery or signal issues. Try replacing the battery and holding the unlock button for over ten seconds to reboot the system. If that doesn't work, the remote might be broken, so use the spare key to manually open the door, then insert it into the ignition and turn it twice. If it's a system malfunction, don't force it—close the windows, stay in the car, turn on the hazard lights, and wait for help or call roadside assistance. Avoid placing the key near your phone, as signal interference can accidentally trigger the anti-theft system. Remember, Cadillac has OnStar—you can call customer service at 400 to request remote unlocking, but you'll need to prove ownership. During regular maintenance, ask the technician to check the anti-theft module to prevent future issues.
