If your 2005 Cadillac STS is displaying "TheftLock" on the navigation and radio screen after replacing the battery, it means that the anti-theft system has been activated. Here are the steps you can take to unlock the system:
1. Turn the ignition key to the "On" position. Don't start the car, just turn the key to "On" position.
2. Wait for the "TheftLock" message to disappear from the navigation and radio screen. This may take up to 10 minutes.
3. Press and hold the "1" and "4" buttons on the radio simultaneously for several seconds until "000" appears on the screen.
4. Use the "TUNE" knob to enter the code that was provided with the vehicle's owner's manual. If you don't have the code, you will need to contact a Cadillac dealership or a certified mechanic to retrieve it for you.
5. Once you entered the correct code, press the "AM/FM" button to unlock the radio and navigation system.
If all doesn't work, it's time to contact a Cadillac dealership or a certified mechanic to help you sort it out.
Oh well, hey, if you got the panel off, you've already accomplished the near impossible! And no thanks to safelite, very rude of them. The bars or rods should be able to be pushed or pulled to ...open door latch, or work locks. Is that the kind of bars you mean? If so, find the door lock and get that unlocked, then the door. If it isn't like I picture it, get a good ole Cadillac person to open it for you!
You will need to contact Cadillac service at your local dealership. Give them the serial number on the radio. They can then pull the anti theft lock code from their companies archive. The serial number on the radio is typically tied to a VIN, but since you bought just the part, they can't search that way. Hope that helps.

Dealership Codes

Troubleshooting
If you fail to enter the correct code eight times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode. Thank you for using fixya and good luck
1.) To begin, if your radio is displays LOC, then proceed to step 2. If your radio says INOP, then turn your ignition to the RUN position, and turn the radio ON. You must leave it like this for a minimum of 1 hour (not 59 minutes) to clear the INOP message. I would wait 1 1/2 hours just in case doing it too early causes the timer to start over.
2.) Turn your ignition to RUN (if not already), and your radio to OFF. Press and hold preset buttons 2 and 3 for around 5-10 seconds to obtain a scrambled version of your radio's original factory set code.
3.) Call a GM dealer with this code. Tell them you are with a local shop i.e. I am Joe with Good Year Highway Tire; Then tell them: We have a 2000 Saturn SL we just changed a battery in and the radio is now locked. My mechanic pulled the pre-code. Could you give me the code? This usally works at no charge.
Once you have the code write it down. Keep atleast 2 copies. Hope this helps!
